  • fftools/ffmpeg : reduce -re to -readrate 1

    fftools/ffmpeg : reduce -re to -readrate 1

    They are exactly equivalent, so there is no point in maintaining a
    
separate flag for -re.

  • lavfi/vf_libplacebo : switch to activate()

    6 mai 2023, par Niklas Haas
    lavfi/vf_libplacebo : switch to activate()

    To present compatibility with the current behavior, we keep track of a
    
FIFO of exact frame timestamps that we want to output to the user. In
    
practice, this is essentially equivalent to the current filter_frame()
    
code, but this design allows us to scale to more complicated use cases
    
in the future - for example, insertion of intermediate frames
    
(deinterlacing, frame doubling, conversion to fixed fps, ...)

  • Converting webm to mpeg-ts loses audio channel

    2 juin 2023, par Nobunaji

    I'm using the following ffmepg command :

    


    ffmpeg -i path/to/input.webm -c:v libx264 -c:a copy -f mpegts path/to/output.ts


    


    Or the equivalent in fluent-ffmpeg :

    


    const ffmpeg = require('fluent-ffmpeg');

ffmpeg('path/to/input.webm')
  .videoCodec('libx264')
  .audioCodec('copy')
  .output('path/to/output.ts')
  .format('mpegts')
  .run();



    


    My input file has 2 audio channels (stereo), a bitrate of 64kbps, an audio sample rate of 48.000 kHz and is encoded in opus. But for some reason, my output file loses all of that.

    


    Do i not understand what -c:a | .audioCodec('copy') copy does ?

    


    According to this website taken from this wikipedia article opus is a supported codec in MPEG files.
