Actual Behavior

Encoding failed

Steps to Reproduce

I want to convert a mp4 video file to mkv but it was failed. Here is the log:

ffmpeg failed to execute command '/usr/local/bin/ffmpeg' '-y' '-i' 'mypath/SampleVideo_1280x720_20mb.mp4' '-ss' '00:00:05.00' '-threads' '12' '-vcodec' 'libx264' '-acodec' 'libfaac' '-b:v' '1000k' '-refs' '6' '-coder' '1' '-sc_threshold' '40' '-flags' '+loop' '-me_range' '16' '-subq' '7' '-i_qfactor' '0.71' '-qcomp' '0.6' '-qdiff' '4' '-trellis' '1' '-b:a' '128k' '-pass' '1' '-passlogfile' '/var/tmp//ffmpeg-passes5897d94ab3505dfux7/pass-5897d94ab358e' 'mypath/SampleVideo_1280x720_20mb.mkv'

I tried to run that command in terminal and got this error: Unknown encoder 'libfaac'. A quick search on google showing that libfaac had been removed from ffmpeg. Any suggestions for this issue?

I had the same problem today. I solved it by adding 'aac' to the getAvaibleAudioCodecs function in the X264 class. It appears that FFmpeg ded deprecate libfaac.

now it looks like:

/** * {@inheritDoc} */ public function getAvailableAudioCodecs() { return array('aac','libvo_aacenc', 'libfaac', 'libmp3lame', 'libfdk_aac'); }

Then I convert the file this way:
$video->save(new X264('aac', 'libx264'), $sDownloadDir.$file->getTitle().'.mp4');
This is for html5 friendly video/audio.

We might want to update this in the repo?

Thanks, new X264('aac', 'libx264') did the job

Hi @DHoogland,
You shouldn't have to change the core files. This has already been fixed in 0.7.0 by @Neck, in PR #257.
Since this issue is solved, and you found the proper way to use it, I'll close it.
