• Problem accessing audio track from mp4 file

  20 décembre 2019, par Thomas Spycher

  For a TV Project we want to transcode the source videofiles to other formats. The Sourcefiles are fragmented mp4 files. Destination format could be mp4 or any other format.
  The sourcefile contains multiple audio tracks for different codes (aac, eac3, aac-otherlanguage).

  Something with this files is odd. I can play them without problems on quicktime or VLC. Import them into Premiere for example ends up with the video but without sound.

  Converting them on AWS MediaConvert results in weird issues as well like (depending on the settings) :

  • No audio frames decoded on [selector-(Audio Selector 1)-track-1-drc] (selecting aac audiotrack (Track:1))
  • Decoder : [Dolby decoder error : failed to configure to stream in first 100 frames] (selecting eac3 audiotrack (Track:2) )

  I’m able to convert the files with Handbreak and the result is a MP4 file with one audiotrack which is working everywhere. I’m trying to figure out whats odd with this file to make them working with AWS MediaConvert.

  Here is the ffprobe output of one of the files :

• ExecutionFailureException : ffmpeg failed to execute command

  31 janvier 2020, par ItsJasonn

  I am trying to concat multiple videos to eachother using PHP and the FFMpeg library. I am able to execute the binaries on my 32-bit Linux server flawless, but I am still getting this error saying...

  Fatal error : Uncaught Alchemy\BinaryDriver\Exception\ExecutionFailureException : ffmpeg failed to execute command ’/var/services/web/vendor/libraries/ffmpeg/ffmpeg’ ’-f’ ’concat’ ’-safe’ ’0’ ’-i’ ’/volume1/@tmp/ffmpeg-concatcg8R3L’ ’-c’ ’copy’ ’/volume1/web/vendor/php/out-1580427487.mp4’ : Error Output : ffmpeg version 4.2.1-static https://johnvansickle.com/ffmpeg/ Copyright (c) 2000-2019 the FFmpeg developers built with gcc 6.3.0 (Debian 6.3.0-18+deb9u1) 20170516 configuration : —enable-gpl —enable-version3 —enable-static —disable-debug —disable-ffplay —disable-indev=sndio —disable-outdev=sndio —cc=gcc-6 —enable-fontconfig —enable-frei0r —enable-gnutls —enable-gmp —enable-libgme —enable-gray —enable-libfribidi —enable-libass —enable-libfreetype —enable-libmp3lame —enable-libopencore-amrnb —enable-libopencore-amrwb —enable-librubberband —enable-libsoxr —enable-libspeex —enable-libsrt —enable-libvorbis —enable-libopus —enable-libtheora —enable-libvidstab —enable-libvo-amrwbenc —enable-libv in /volume1/web/vendor/php-ffmpeg/php-ffmpeg/src/FFMpeg/Media/Concat.php on line 149

  Does anyone know what the issue could be ? Thank you !

  EDIT 1 :
  It seems PHP does not let me create files (I think). PHP FFMPEG attempts to create a temporary file in my /volume1/@tmp/ folder, but no file is being created. I have checked everything on Google, but nothing works for me. I have also checked the permissions and I have 777 on all of my folders.
