  • Other interesting software

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • Wrong duration of the result video when using ffmpeg filter complex concat [closed]

    9 décembre 2023, par Igor Chubin

    I am trying to do a trivial task of concatenating
several segments of the original video/audio
into a new file (and dropping the rest) :

    


        ffmpeg -i bdt.mkv -filter_complex '
    [0:v]trim=start=10.0:end=15.0,setpts=PTS-STARTPTS[0v];
    [0:a]atrim=start=10.0:end=15.0,asetpts=PTS-STARTPTS[0a];
    [0:v]trim=start=65.0:end=70.0,setpts=PTS-STARTPTS[1v];
    [0:a]atrim=start=65.0:end=70.0,asetpts=PTS-STARTPTS[1a];[0v][0a][1v]
    [1a]concat=n=2:v=1:a=1[outv][outa]' -map [outv] -map [outa] out.mp4


    


    When I am trying to watch out.mp4 after that, it has the original duration of bdt.mkv (70 minutes) and not 10 seconds, as I would expect.

    


    What am I doing wrong ?

    


    Update 1.

    


    (exactly as Scott Codez suggested)

    


    The problem is related to the formats. If the output format is mkv too, the problem disappears. But when I use mp4, that I need, the problem persists.

    


  • Covert a file from mp4 to a file that HTML video tag can display

    26 juin 2019, par Trying_To_Understand

    I have a mp4 file and I want to display it in HTML. The problem is that it won’t, not only in HTML but also in my player. In VLC I can watch the video but there is no sound. Maybe the file is corrupted ?
    This is the output when I run ffmpeg -i my_file.mp4 :

    [h264 @ 000001b4afc61880] decode_slice_header error
    
[h264 @ 000001b4afc61880] no frame!

    Last message repeated 1 times

Input #0, mpeg, from '150_2.mp4':

    Stream #0:0[0x1e0]: Video: h264 (High), yuv420p(progressive), 1280x720, 25 fps, 25 tbr, 90k tbn, 50 tbc
    
    Stream #0:1[0x1c0]: Audio: pcm_alaw, 8000 Hz, mono, s16, 64 kb/s
    
At least one output file must be specified.

    Can I convert this with ffmpeg to a good quality of video and audio ?

  • Passing file name in youtube-dl post-process script without file extension suffix

    2 avril 2021, par Arete

    The documentation for youtube-dl says I can run a post-process command with the --exec option.

    


    Using Windows, here is an example I have tried :

    


    youtube-dl --exec "ffmpeg -i {} -ac 2 -c:a libfdk_aac -cutoff 20000 -afterburner 1 -vbr 0 {}.m4a" https://www.youtube.com/watch?v=sw9DlMNnpPM


    


    Note that {} passes the file name to the post-process command. For example filename.webm.

    


    The problem is that {} includes the file extension.

    


    How can I pass the file name to the post-process command without the file extension ?

    


    For example, if I were to convert the video, I would rather avoid getting an output name like filename.webm.m4a. Needless to say, I would rather want filename.m4a.
