Codecs in avconv Vers 9.16 not recognized

Hi!

Firstoffall: Thanks for that great module!

I have installed the video module on a Ubuntu 14.04 server (Trusty Thar), which shippes avconv Vers. 9.16.

When I specify the path to avconv on /admin/config/media/video/transcoders, I get the following Error:
"FFmpeg version 9.16 was found, but no supported codecs could be found"

I did the following to debug:

I have a second Server which runs Debian squeeze which comes with 8.6. On that server video transcoding runs fine.

I took the commandline that is executed to transcode when uploading a video on the older debian server an run the same command on the newer ubuntu server and that also works fine.

/usr/bin/avconv -i 'test2.avi' -vf 'scale=0:360' -strict experimental -vcodec 'libx264' -acodec 'aac' -ac '2' -ar '22050' -y '/tmp/test2.mp4'

So i think that maybe it is only the check funktion that is run when specifiying the transcoder which does not understand the output of the new avconv Version.

I added the Output of /admin/config/media/video/ffmpeg-info?ffmpegpath=/usr/bin/avconv from the new Ubuntu-Server as an attachment to this issue.

Is there a Chance that I can run the module with the "on-board" new avconv version, or do i have to compile original ffmpeg?

Yours
