ffmpeg lacks Raspberry Pi hardware encoding support

[Ben]

Summary of the bug:
While gstreamer has a omxh264enc sinc which does use the raspberry pi's built in h264 hardware encoder, ffmpeg will not use this one.

How to reproduce:

% ffmpeg -i input -c:v libx264 ...
ffmpeg version <any>

Now that there's a floss driver, I hope such an enhancemant could be done.

git of gst-omx: ​http://cgit.freedesktop.org/gstreamer/gst-omx/

Beware, the raspberry pi page is barely useable today (April 1st).

Are there any news about allowing hardware decoding and/or enconding on the Raspberry Pi?
The Raspberry Pi 2 model uses the same GPU from the older model.

I believe decoding h264 could be implemented first to allow various players to really work on the device instead of only omxplayer. Also Chromium do use ffmpeg to play HTML5 video content, so this would allow a decent browser to be used.

The h264 encoder is accessible through OpenMAX. This should be enough information to make use of it:

along with the decoder code in

I believe this was merged before 3.1 was released.
