| Bug? | yes |
| New Feature? | no |
| Version Used | 0.6.1 |

Actual Behavior

PHP-FFMpeg is sending me a PHP Fatal Error.

PHP Fatal error:  Uncaught Alchemy\BinaryDriver\Exception\ExecutionFailureException: ffmpeg failed to execute command '/usr/bin/avconv' '-y' '-i' '/media/disk/git/video-encoding/videos/test.mkv' '-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' '/tmp/ffmpeg-passes579341d3262b8kkw4s/pass-579341d32643e' '/media/disk/git/video-encoding/test-X264.mp4' in /media/disk/git/video-encoding/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/ProcessRunner.php:100

As I'm executing the command PHP-FFMpeg ran on the console I see that avconv is complaining about the audio-encoder libfaac.

I also ran that command with ajusted parameters ('aac' instead of 'libfaac') and got the following:

Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

Here is my execution log created with monolog:

Expected Behavior

Save my file to desired location encoded with the expected codec (H.264) in .mp4 format.

Steps to Reproduce

Transcode mkv video to .mp4 (H.264) with PHP-FFMpeg on my platform:

$this->video->save(new \FFMpeg\Format\Video\X264(), $path);

Possible Solutions

At this time now I kind of think, that PHP-FFMpeg got this "libfaac" from some kind of previous command with avprobe. If not: might some deprecated relation between AAC-codec and libfaac.

[Ninos]

Same problem here. Just can convert to webm. x264 lib is installed.

System: Debian Jessie arm64

Problem solved by installing newer libraries from multimedia rep. About the frame images bug I've created a new issue:
https://github.com/PHP-FFMpeg/PHP-FFMpeg/issues/235

[jankal]

@Ninos What did you do to get this to work? I now fully recompiled FFMpeg v 3.2.1 from source on my machine with following options:

./configure --enable-gpl --enable-postproc --enable-swscale --enable-avfilter --enable-libmp3lame --enable-libvorbis --enable-libtheora --enable-libx264 --enable-libx265 --enable-libspeex --enable-shared --enable-pthreads --enable-libopenjpeg --enable-nonfree

Though --enable-libfaac is not available with this FFMpeg version anymore.
Before that I installed all libraries:

apt install libmp3lame-dev libvorbis-dev libtheora-dev libspeex-dev yasm pkg-config libfaac-dev libopenjpeg-dev libx264-dev libx265-dev

To now have the following ffmpeg output:

  libswresample   2.  3.100 /  2.  3.100
  libpostproc    54.  1.100 / 54.  1.100

And it still does not work!

What could I try next?

[jankal]

I now fixed this.
I followed #137 and changed the constructor for /src/FFMpeg/Format/Video/X264.php
I updated /src/FFMpeg/Format/Video/X264.php to:

22: -    public function __construct($audioCodec = 'libfaac', $videoCodec = 'libx264')
22: +    public function __construct($audioCodec = 'aac', $videoCodec = 'libx264')
54: -        return array('libvo_aacenc', 'libfaac', 'libmp3lame', 'libfdk_aac');
54: +        return array('libvo_aacenc', 'libfaac', 'libmp3lame', 'libfdk_aac', 'aac');

I may now file a Pull Request for that.

[Ninos]

I just installed latest packages on my debian jessie machine to get my problem fixed. Thx for the changes. Is it possible to create a PR for that? :)

[jankal]

Maybe. But I also found a already existing PR. Look here for my changes: jankal/PHP-FFMpeg and this PR #222 should already start to fix this.

[jankal]

@Ninos which ffmpeg version do you use?

[Ninos]

I'm using following version:

Using this version I only have following issue with mkv's:

[jankal]

Okay. @Ninos Then you are not affected. Should be starting at like FFMpeg 3.2 to get that problem. Libav is affacted too, as I see now.
