Version 0.2.2 - 14.May.2010
* Fix packaging dependencies
* Fix a crash in the FFmpeg decoder on close
* Fix OpenGL texture internal format (Clutter)
* Fix foreign window size for embedding (Totem)

Version 0.2.1 - 12.May.2010
* Fix integration within the playbin2 pipeline
* Fix vaapidecode to expose the HW supported caps only
* Add GstXOverlay interface to vaapisink (Totem media player)

Besides, Clutter now supports VA-API acceleration through GStreamer:

I'm running 10.4. I need a patch to libavcodec (or a recent ffmpeg? not sure if ffmpeg has the neccessary headers) for vaapi headers. Anyone know where I can get this?

I just grabbed a tarball from here:

http://www.ffmpeg.org/download.html

And now got it working with Totem. Doesn't seem to do scaling yet though, as illustrated by the screenshot.



But anyway great work Gwenole. Now if only ATI/AMD did their part to get XvBA working with Evergreen.

It does but the algorithm I use to compute the render size is probably broken. Normally, it scales to fit the window while preserving the aspect ratio. So, in any case, you should only have black bars either top/bottom or left/right.

Could you please report the outcome of:
$ GST_DEBUG=vaapisink:5 totem some args
?

+ the size of your Totem window + the size of the clip. Those should be available in the log, but just to make sure I retrieve the right data.

Sure. The log file is over here:

The reported video size (1280x688) in the log is correct. The size of allocated to the video window from Totem is approximately 1680x856.
(whole Totem app is 1680x1002)

Hi,

A new version is now available at:

* Fix VC-1 decoding through the playbin2 pipeline

[gbeauche]

Sure. The log file is over here:

Thanks, I have released a new version. There is no fix for your problem yet but extra debugging information that may be useful to me. I have an idea of the problem but I would like to confirm, so if you could have new dump, that could help. Thanks.

I have uploaded a 0.2.4-pre1, it might help your case. At least, I am now using the same algorithms as in xvba-video/vdpau-video to detect foreign window size changes.

[monraaf]

Nope also not working with 0.2.4-pre1. Just to be clear it's only upscaling that doesn't work here, downscaling does work.

Here's the log, same sizes as before:

OK, thanks. This should be fixed in the newly uploaded 0.2.4-pre2.
