  • problem in concatenating mass online video urls using ffmpeg [duplicate]

    25 mai 2021, par JohnTerry

    I want to concat n number of videos together using ffmpeg which can also have more than one codec or different resolutions.
I know how to do it with fixed number of videos but input_videos.txt can contain any unknown number of videos. I checked relative posts but they did not have a solution for my problem.

    


    the command i am using for concatenating videos is -

    


    cmd = "ffmpeg -safe 0 -f concat -protocol_whitelist file,http,https,tcp,tls,crypto -segment_time_metadata 1 -i {} -vf select=concatdec_select,scale=1280:720 -af aselect=concatdec_select,aresample=async=1 -c:v libvpx-vp9 -deadline good -cpu-used 5 -c:a libopus {}".format(input_videos.txt, output_video.webm)


    


    Is there a way to achieve the functionality i want ?

    Adaptive motion search control

    This commit enables adaptive constraint on motion search range for
    smaller partitions, given the motion vectors of collocated larger
    partition as a candidate initial search point.

    It makes speed 0 runtime of bus at CIF and 2000 kbps goes from
    167s down to 162s (3% speed-up), at 0.01dB performance gains. In
    the settings of speed 1, this makes the runtime goes from 33687 ms
    to 32142 ms (4.5% speed-up), at 0.03dB performance gains.

    Compression performance wise, it gains at speed 1 :
    derf 0.118%
    yt 0.237%
    hd 0.203%
    stdhd 0.438%
