    I installed ffmpeg, added it to path and I can find it in command line, but in jupyter notebook when I try to use bcr.bar_chart_race function it returns me this error message

  • Libvpx unknown encoder with php exec

    5 juin 2016, par Justin Tullock

    I have centos7 with ffmpeg compiled with libvpx. I can run

    ffmpeg -i gif.gif -c:v libvpx -crf 12 -b:v 500K webm.webm

    which works perfectly but when I try the same command with php exec() it returns this :

  • Specifying input duration of .aac with ffmpeg

    28 septembre 2020, par Jademalo

    I had an error with an mp4 recording, and after recovering the video and audio streams I've still got an issue. The aac audio file is 160kb/s CBR. However, ffmpeg returns this when trying to work with it ;

    


    [aac @ 000001187e6944c0] Estimating duration from bitrate, this may be inaccurate
Input #0, aac, from 'result.aac':
  Duration: 00:38:41.01, bitrate: 174 kb/s
    Stream #0:0: Audio: aac (LC), 44100 Hz, stereo, fltp, 174 kb/s


    


    That duration and bitrate is totally wrong. It should be 42 minutes long, and it definitely has a bitrate of 160 kb/s.

    


    This results in the audio being very inconsistently timed, as well as having all sorts of other issues. It's very weird.

    


    Is there any way I can specify that the input is 160 cbr to try and wrangle it back into a usable file ?
