  • Trying to concatenate multiple videos with multiple audio streams using ffmpeg

    25 avril 2019, par Toto

    I’m trying to concatenate 3 mp4 videos, each contains 3 audio streams using ffmpeg, since I couldn’t merge them with other software because of differences in the codecs private data.

    Since the files have different codecs I’m trying to use the concat video filter but I can’t seem to get it to work. The output turns out to be an unplayable file. I’m trying to specify the input files, and every media stream, then telling the software to concatenate it and copy it to the output file.

    ffmpeg -i A.mp4 -i B.mp4 -i C.mp4 -filter_complex  '[0:0] [0:1] [0:2] [0:3] [1:0] [1:1] [1:2] [1:3] [2:0] [2:1] [2:2] [2:3] concat=n=3:v=1:a=3 [v] [a1] [a2] [a3]'  -map '[v]' -map '[a1]' -map '[a2]'-map '[a3]' output.mp4

    The complete log :

    ffmpeg -i A.mp4 -i B.mp4 -i C.mp4 -filter_complex  '[0:0] [0:1] [0:2] [0:3] [1:0] [1:1] [1:2] [1:3] [2:0] [2:1] [2:2] [2:3] concat=n=3:v=1:a=3 [v] [a1] [a2] [a3]'  -map '[v]' -map '[a1]' -map '[a2]'-map '[a3]' output.mp4

  • FFmpeg retrieve a specific program from TS file

    8 mai 2017, par chang jc

    I tried to retrieve a specific program from a TS file.
    Said :

    Input #0, mpegts, from 'DVB_T_good.ts':

    Then I tried to retrieve a specific program as :

    ffmpeg -i INPUT -map 0:p:1344 OUTPUT

    It succeeds greatly but the only thing I noticed is :

    it seems to apply transcode (decode & encode again) to the output implicitely ?
