New packages in Extras-Testing: gPodder 2.12, TV out control widget

gPodder 2.12 "The Odyssey of Flight 33" has been released, which is purely a bugfix release for those of you who found an empty podcast list after skipping a gPodder version during upgrades (this release fixes both the initial problem and tries to recover databases for which migration has failed). The updated package is also available in Diablo Extras already for N8x0 users. Please test and vote for gPodder 2.12-1 in Extras-Testing!

A new desktop widget written by Ville Syrjäl has been packaged for Extras. TV out control lets you control advanced features of the N900's TV out such as aspect ratio and scaling - those settings are not accessible from the official control panel applet, which is closed source (vote for that bug if you'd like to see it open sourced and improved through the Community SSU). Please test and vote for the TV out control widget in Extras-Testing!

New tutorial: PySide/QML on MeeGo

In addition to my old PySide tutorials, there is now a proper PDF guide for PySide development on MeeGo available. Except for packaging, all steps apply to Maemo as well, and this is the document that includes the first gPodder QML UI code example (the final gPodder QML UI will be totally different and "much cooler", though).

As part of the new year's cleanup, I also dug out the old MTF UI demo of gPodder and put its source online here - for third party applications, QML is now the preferred UI over MeeGo Touch, so this might not be of much use for you now, but maybe somebody can put it to good use.

gPodder 2.11 in Extras-Testing fixes YouTube downloads

A new version of gPodder is out. If you are having problems with YouTube downloads recently, this release is for you. There are also some other minor changes and fixes (detailed changelog for gPodder 2.11). No translation updates or major new features, though. Grab the new package from Extras-Testing. The usual disclaimers apply. If you can, please test and vote for gPodder 2.11-1 in Extras-Testing, so other users can enjoy the fixes as soon as possible.

As always, a new Diablo package has also been uploaded and should be available in Diablo Extras for all N8x0 users soon.

PySide/QML tutorials online, workshop next Sunday

To get myself accustomed to PySide UI development using Qt Quick (aka QML) and to check out what works already and what does not, I've experimented with creating some common elements that I'd use in an application (i.e. a QML version of gPodder - a blingy demo already exists) and decided to share my experiences and results as tutorials.

Here are all the tutorials in their current state:

• Selectable list of Python objects in QML
• Multi-selection lists in Python with QML
• Defining and using constants from PySide in QML
• Using QtWebKit and QML with PySide
• Updating QML content from Python threads
• Utilizing Qt Quick Colibri in PySide
• Filling and reading QML UI forms from Python
• Auto-generating QObject from template in PySide
• Using QtMobility sensors and QML from PySide

Screenshots are available on Flickr:

I'd like to get some feedback on whether or not the tutorials worked for you and were helpful and what else you would like to see. You can try out all the examples on your N900 today! Just install python-pyside and python-qtmobility (for the last example) from Extras-Devel and copy the examples from the Wiki. The usual disclaimers for software in Extras-Devel apply.

In related news, there will be a PySide/QML workshop at the December meeting of the Python User Group Austria, so if you happen to be in or around Vienna on Sunday, 2010-12-12, stop by at the Metalab and meet fellow Pythonistas.

gPodder 2.10 for Maemo 4 and Maemo 5 released

As promised last week, a new release of gPodder is out. The package for Maemo 5 is already in Extras-Testing, so test it and vote for it. The package for Maemo 4 has already been uploaded to the autobuilder and should be available shortly.

This new release brings yet another round of UI improvements, and it also incorporates the feedback that I got at the MeeGo Conference:

• Expose "Pause subscription" in UI
• Multi-delete in episode lists (Maemo bug 5182)
• Setting for episode auto-delete on startup
• Custom episode list model (faster loading)

You can find a detailed ChangeLog at gpodder.org/changelog/2.10.

If you are not yet a user of gPodder, why not take the opportunity to try it out? You could subscribe to the MeeGo Conference 2010 Video Podcast (Yahoo Pipe) and (re-)watch the sessions on your device. Of course, audio and video podcasts are supported as well, as are YouTube user channels and Soundcloud users.

Maemo 5 app UIs: {The,A} big picture

Sooner or later it will be necessary to create a QML UI for gPodder if it is to integrate nicely with devices on which Qt is the "native" toolkit for third party apps. At the moment, the reusable UI elements that can be used with QML (Qt Components) have not yet been officially released (the Git repository is available on Gitorious, though), and there are no UI style guidelines for Harmattan out (yet?). I'm also not able to locate UI style guidelines for QML apps on Symbian^3, and there are only a few small sample QML apps out right now.

Let's look at what we have on Maemo 5 right now. Here's a simplified overview of the current Maemo 5 UI of gPodder:

You can also check out the full-size image (~ 3.5 MB).

The UI follows the Maemo 5 Style Guide where it makes sense and tries to come up with better solutions where the Style Guide does not have a definitive answer. I'd like to hear your opinion about the current UX of gPodder and how these concepts can be translated into a QML app that integrates nicely with "future" UIs (Harmattan, S^3). The new-style episode list that can be seen in this picture will be made available with the next release that will be out Really Soon Now™.

Please test: MaePad 1.9, MaePadWeb 2.1, Trophae 6

Version 1.9 of MaePad is out, with a new translation into Catalan, updated Finnish (thanks to Marko Vertainen) and German translations, a "No items" indicator in empty checklists and full auto-rotation support (detailed changelog).

The File Transfers application seemingly does some weird things to "Open file" dialogs in other apps (not only MaePad, but reportedly also Xournal), so MaePad now conflicts with it until the problem is fixed (this means you can't have both "File Transfers" and "MaePad" installed at the same time). Test and vote for MaePad 1.9 in Extras-Testing!

Also new is MaePadWeb 2.1, which adds a missing dependency on python-simplejson. The app worked fine for me since the initial release, so I'm also promoting it to Testing now. Test and vote for MaePadWeb 2.1 in Extras-Testing!

And as a third release this week, I noticed that Trophae, the PS3 Trophy Viewer app, didn't get its newest release (6) uploaded to Fremantle Extras-Devel for two months, so I've re-uploaded it, and also put it up for testing. And even though the code is lame, it's now published in a Git repository if you want to hack on it. Test and vote for Trophae 6 in Extras-Testing!

A new release of your favourite podcatcher is coming in the next few days. There is still time to submit updated translations :)

MeeGoConf 2010: Fun, QML, gPodder, Python

I've attended the MeeGo Conference 2010 in Dublin this week. Meeting people, playing werewolf or table tennis and discussing MeeGo Python are just some of the great things about this conference.

One of my burning questions for third-party app development ("QWidget? MeeGo Touch? QML? Which one of those?") was answered with "QML". I've played with QML before, and it's great, but right now, one has to work on a very low level (as in "design your own buttons") and without any UI style guidelines. Let's hope the Qt Components provide reusable UI parts there and that the style guidelines are published as soon as possible.

I've also got some gPodder feedback: Niels suggested subscription pausing and auto-deletion of episodes (both are already implemented and just need exposure as UI elements). Murray suggested a custom TreeModel implementation for the episode list, which I've started working on now. Mike suggested the often-requested multi-episode deletion feature, which is also something I plan for the next release.

On Wednesday, we had a Python BoF to discuss the state and future of MeeGo Python. I'm looking forward to using PySide for the QML UI of gPodder. A PySide/QML workshop is planned for the next PyUGAT meeting, so join in if you are in Vienna in early December.

Oh, and the IdeaPad that we got from Intel is great. Thanks a lot for that. Will come in handy for prototyping and testing Touch UI interfaces!

Hope to see you again in a future MeeGo event :)

gPodder 2.9 for Maemo 5 in Testing

A new release of gPodder is out. Test it and vote! It has got some fine-tuning of the UI for Maemo 5 users that you will discover one by one. I just want to highlight two UI changes that should enhance the user experience, and compare them to what the previous version had.

The episode list

gPodder 2.8 introduced MAFW integration, and with it came the ability to save position and duration information for each episode. This was displayed in the episode action dialog, but not in the episode list. We now display the position and duration in the episode list, which allows you to quickly scan for an episode depending on its duration (or check how far you have come for a given episode). In the "All Episodes" list, we also display the podcast name for each episode so that it is clearer from which podcast an episode is coming (the content of the episode "Mini Book Reviews" is much more predictable if you know that it comes from "Python411").

Updating feeds

Previous versions of gPodder changed the "Check for updates" button into a combined progress indicator and cancel button. It was not really obvious to first-time users that you can cancel the feed update, and if you accidentally tapped the button twice, the feed update would be cancelled and you might be confused. gPodder 2.9 introduces a fancy new progress bar that appears (and even slides in and out thanks to hildon.AnimationActor) during the update and has a more obvious red cancel button. With the gained screen space (the progress bar is much bigger), we can also show more information about the update process, like the name of the updated podcast.

A detailed changelog can be found at http://gpodder.org/changelog/2.9. Of course, the Maemo 4 (N800, N810) package has also been updated, and is available from Diablo Extras right now.

Fast MeeGo Handset UX on a N900 (Video)

I've had the chance to play around a bit more with the MeeGo Handset UX on the N900 yesterday (1.1.80.0.20101001.1). Carsten provided experimental graphics drivers, which still crash at a few points, but for the first time provide acceptable performance in the UI. I also decided to build the gPodder MeeGo Touch Prototype UI against libmeegotouch. Unfortunately, there's no SDK yet, so I had to use zypper on the device (via SSH) to install libmeegotouch-devel, make and gcc-c++ and then take a long coffee break after entering qmake ; make. As it's using plain Qt, the TRG binary built from the Fremantle SDK worked fine on the device.

If you don't see the embedded video, click here: MeeGo Handset UX on a N900 (w/ TRG, gPodder UI test, HW-accelerated).

It's about time...

...displayed inside gPodder. Not only the total time of a podcast episode, but (thanks to the MAFW integration that has been added in 2.8) also the position that you stopped listening to, so you know how much time is remaining. There are several possibilities how to display the progress: A circle sector image, a "position/total" text display and a "remaining" text display. Right now, I opted for the "position/total" display (with "total" in cases where you haven't started listening to an episode). Here's how it looks in the current development version of gPodder:

If I remember correctly, the idea for this came up during the Barcelona Long Weekend and was suggested by Tuomas while we were discussing gPodder's UX. Back then gPodder did not store any kind of time-based length information in its database - only the file size in bytes, which isn't that helpful for listening purposes. But since then the work on gpodder.net and the desire to synchronize episode status information between different devices has put everything in place that's needed to detect the duration of episodes (it's even provided as <itunes:duration> (spec) in some RSS feeds) and with the MAFW integration to detect the current playback position when playback is stopped.

If you are using gPodder 2.8 and the built-in Media Player, gPodder already collects this information, so when the next release comes out, you will immediately have some useful data there. This should also help you in deciding which episode to pick on your commute.

What do you think of this feature? Is the current representation the best one, or would something else be more useful to you?

Playing around with MeeGo Touch

While the MeeGo Touch Python Bindings are still not packaged and released, I though I'd give the C++ library a try and have a look through the class hierarchy. After getting the basic "Hello World" app running, I decided to create an application that can load the list of subscriptions from gPodder's SQLite database:

This view uses MContentItem, which already provides an icon and two lines of text - correctly styled and ready to go. Menu and toolbar items are MAction objects that can either appear everywhere or only at specific places (e.g. only in the toolbar). The great thing is that this all works on your Desktop in a normal window, so testing applications on your computer will be much easier with MeeGo Touch than it is with Hildon (which does not really run without its own hildon-desktop session in Xephyr).

The screenshot above is from the prototype written in C++, and shows how a gPodder MeeGo UI could look like. The MeeGo Touch UI of gPodder will be implemented in Python once the bindings are ready - the framework seems to be fun to work with so far. If you would like to play around with it yourself: MeeGo Touch is available from the MeeGo PPA of Ville M. Vainio if you are on Ubuntu and don't want to build it yourself.

gPodder 2.8 for Maemo 5: Notifications and MAFW integration

It's been some time since the last gPodder release, and I've been busy adding some nifty features to make the best use of the on-board facilities of Maemo 5. As already mentioned in a previous post, this new version comes with built-in notification support. After installation, you might have to re-start hildon-home (or your device) for the changes to become effective. That's what you will get when new episodes are found:

The other and more "invisible" change is that gPodder now listens to MAFW and also talks to it at times. MAFW is the backend of the Media Player application, and you profit in two ways from this integration:

• The last playback position and duration of an episode are displayed in gPodder and synchronized to gpodder.net
• Playback can be resumed even with the Media Player application

This means that users of the normal Media Player application will benefit from all the goodies that were previously only available in combination with Panucci. Combined with the new notifications, this makes for yet another great release with even better integration into the Maemo 5 environment.

gPodder 2.8 is now available from Extras-Testing, so please test, review and vote on the package.

gPodder running in the MeeGo Handset UX for N900

Three days ago, a new MeeGo Handset UX image has been released for the N900. I wanted to try out gPodder on it to see how far I could come without any coding...

It was quite easy to get things going: Download the image, dd it to a MicroSD card, boot the kernel (detailed instructions) and set up USB networking. After that, I could ssh into the environment (the root password is meego) and have a look around.

Instead of using apt-cache and apt-get to search for and install packages, I utilized yum to search for and install PyGTK. Then, I used rsync to copy my Git checkout of gPodder to the device. There are two additional dependencies for gPodder that aren't yet available in the MeeGo repositories, namely feedparser and mygpoclient, so I just copied the Python modules from my Laptop into the src/ folder of the gPodder checkout. Then, just switch to the MeeGo user (su - meego), make sure that the DISPLAY variable is set (export DISPLAY=:0) and start gPodder from the source folder (with bin/gpodder - it automatically loads the modules from the right path) - gPodder says hello MeeGo.

The basic functions work, it's just that the Desktop UI isn't suited for mobile devices (the MeeGo compositor/decorator also has several problems, but that seems to be a more general problem). Python bindings for Hildon aren't (yet ?) available, so I could not test the Maemo 4 or Maemo 5 UIs, but I would like to do a proper Qt/MeeGo Touch-based UI for gPodder, anyway. Let's hope the PyMaemo or PySide teams are quick to release bindings and make them available in the MeeGo repositories, so Python developers can create usable UIs for MeeGo handsets :) Oh, and two MeeGo-Python facts: It comes pre-installed in the N900 image, and the version shipped is 2.6.

In short: Apart from the UI framework, everything is already in place (and working) for Python on MeeGo. With the recent release of Qt Mobility for PySide, let's hope that MeeGo Touch bindings are not that far away.

Desktop notification support in gPodder

Three days ago, Maemo bug 11130 was filed: It complains about gPodder stealing focus when it has finished checking for new episodes in the background. This is true, and I've been bitten by this annoyance several times already, so I decided to finally have a look into the SMS/IM/Phone-style notifications (the "yellow" bubble that merges into your task switcher after some time). Thankfully, Daniel Would (of Witter fame) has published his research results some months ago already, so getting up and running was easy from that point. Here are the results so far:

One problem that I still have not figured out how to fix (even after digging in the hildon-home source tree) is how to attach such a notification to the a given window (or application) instead of having it appear as separate "window" in the task switcher (see the second screenshot). Can somebody in the know give me a hint? On the other hand, the callback for clicking on the notification works fine already and opens the new episodes dialog.

A related change that also prevents gPodder from stealing focus was to replace the progress indicator dialog with a HildonBanner - it might not look so good without a progress bar, but it makes gPodder less intrusive when the user interacts with other applications.

headphoned 1.9 for the N900 is now in Extras-Testing

The beloved Headphone Daemon, who usually sleeps in the darker corners of your N900 and makes sure that you do not embarrass yourself in front of other passengers or pedestrians with whatever kind of experimental music you happen to listen to when the headphones are accidentally unplugged (also known as public transport situations) got a small facelift (also known as code change).

A few changes that have accumulated over the last few months have now been packed up into the shiny new 1.9 release:

• Support for libplayback / whitelisting (by Faheem Pervez)
• Support for pausing Martin Grimme's MediaBox
• Detect headphoned disconnect during active calls and send pause command after the hangup

The last one in this list might be of special interest to some of you who have complained about headphoned not working when the headphones are unplugged during a call. This won't happen now, as headphoned now monitors the call status via D-Bus and keeps track of active calls. When the headphones are unplugged while a call is active, the pause signal will not only be sent right away, but also a second time when the call gets disconnected. This work for all types of voice calls, and should work for video calls as well (untested).

During the summer holidays, I have had less time to do more development and releases, but things are starting to move slowly again - expect new releases of packages like gPodder and MaePad in the upcoming weeks. I'd also love to port gPodder to Harmattan and add a fancy new MeeGo Touch UI on top of it (in March I said that Maemo 6/MeeGo is for later this year - which might be very soon now), so you can all enjoy your favourite podcatcher with the usual native UI support. Let's hope that the Harmattan SDK and/or Harmattan developer images get released for the N900 soon (and then the Python bindings soon afterwards - the PyMaemo team was very fast in previous release cycles), so the community developers have enough time preparing their apps for the next big release.

For now, please test and enjoy this new headphoned release, and don't forget to vote for and comment on the package once you have verified the new release from Extras-Testing.

Fine-grained playback status in gPodder and Panucci

I've just uploaded Panucci 0.9-alpha0 to Maemo 5 Extras-Devel. This package is the first one based on the new codebase, which includes support for sending fine-grained playback status messages to gPodder and also receive metadata about episodes from gPodder. This makes listening to podcasts and managing your listening queue even more comfortable. The following screenshots are from development versions of gPodder, but you'll soon be able to enjoy these new features with the upcoming release. Until then: Please test Panucci 0.9-alpha0 in Extras-Devel (I won't be promoting this package to -Testing yet, but report bugs against it if you try it from -Devel), so we can fix any outstanding bugs until the first final release.

So, what's working so far? gPodder gained the display of the current position and total time in the episode actions dialog:

This position information is automatically sent from the newer Panucci version (so it depends on you using Panucci for playing podcasts). Another cool side-effect is that this information will be synchronized with gpodder.net if you are logged in and have enabled synchronization, so you can finally start playing back episodes on your computer, and then pick up where you left on your mobile phone on the go. You can also view a detailed overview of what parts of an episode are played on gpodder.net:

This is really an important feature milestone for gPodder (and Panucci), and it's nice to finally have playback status and episode duration information inside gPodder. Expect a new gPodder release soon, released together with the new version of Panucci (due to the branching history of Panucci, there are some feature regressions, like missing display orientation controls, but these will be re-added in the next few weeks as we move along).

gPodder 2.6 for Maemo 5: A visual tour

gPodder 2.6 (an app for Maemo that can subscribe to and download podcasts, YouTube videos and tracks from Soundcloud) has been released today. The package is in Extras-Testing, so please test it and vote for it! A package for Diablo (Maemo 4, N8x0) is also available already, and includes some Diablo-specific fixes (the "New episodes available" selection was broken, but works correctly now).

I've prepared some screenshots to compare the UI of gPodder 2.5 for Fremantle with the UI of gPodder 2.6. Here are a few examples:

The episode actions dialog now has a dedicated "Delete" button for downloaded episodes

The settings dialog has proper "Save" semantics now (close the dialog to discard changes, click on "Save" to apply changes) - this has been suggested during UX-Week 1

The progress bar for the episode list has rounded corners (useless, but looks better)

Another feature that isn't visible at first: If you get "New episodes available", and you can't decide from the title of an episode if it's worth downloading, just long-tap the episode and choose "Shownotes" from the context menu to display the complete shownotes in a window.

This release includes improved gpodder.net support (easier configuration, restoring of subscriptions now works on first run), and will feature more fine-grained episode playback status synchronization with the (yet-to-be-released) new version of Panucci.

U-Bahn, Keyboard Repeat Switcher and an updated RaeMote

The last three days can be described as one of the more productive weekends - at least in terms of app count. Two new mini-apps have been uploaded to Maemo Extras: U-Bahn, a scrolling subway plan for Vienna and the Keyboard Repeat Switcher widget. While the former might only be of interest to Viennese locals and the occasional tourist, the latter is really useful when you do more serious work in X Terminal and want your hardware keys to have the "repeat" functionality in the yet-to-be-released PR1.2 firmware update. If you have PR1.2, please try them out and vote for these new packages.

And last but not least: a new version of RaeMote has been released, which adds missing dependencies to the packaging information and also changes the display name of the package to be shorter and searchable. RaeMote is still not in Extras, so your votes are again very welcome on this one.

Coming up: A new version of gPodder is already in the works, bringing you lots of bug fixes and UI refinements that we introduced during the last weeks. Some progress is also being made on getting the new version of Panucci ready, which will bring play position syncing when used in conjunction with gPodder and gpodder.net.

gPodder 2.5 "easter egg": Diablo UI on Fremantle

As you probably already know, all gPodder versions (Linux Desktop, Maemo 4 and Maemo 5) use the same codebase, and as Python is an interpreted language, the choice of which UI to run can be made at run time (you could do this for compiled languages, too, but it's easier for interpreted ones). In current versions of gPodder, this happens by using command-line arguments. gpodder alone will start the Desktop version (which does not work on Maemo for obvious reasons - an "auto-detect" feature might be implemented in the future). On Maemo 5, you will usually want to use gpodder --fremantle, which will start the Maemo 5 UI as you know it (that's also the command that gets executed when gPodder is started from its application icon). On Maemo 4, the command is gpodder --maemo.

If you are a gPodder/Maemo old-timer, you might still remember the "good old days" of two-panel, stylus-based podcast goodness with multiple selections, the funky context menu and the thick toolbar on your N8x0. Ever wondered how that would feel on the N900? Try it out! Simply run gpodder --maemo in X Terminal and give your podcasts a little retro interaction (the database and downloads are the same in both versions and are therefore shared).

Try it out - it might come in handy if you are a stylus cowboy or have really small fingers (or a big N900 and normal-sized fingers...). Also, give the multiple-selection feature in the episode list a try. All you need is gPodder version 2.5, as it contains some compatibility fixes to make the Diablo version not be totally unusable on Fremantle.
