  • Is there an elegant way to split a file by chapter using ffmpeg ?

    18 janvier, par Kattern

    In this page, Albert Armea share a code to split videos by chapter using ffmpeg. The code is straight forward, but not quite good-looking.

    


    ffmpeg -i "$SOURCE.$EXT" 2>&1 |
grep Chapter |
sed -E "s/ *Chapter #([0-9]+\.[0-9]+): start ([0-9]+\.[0-9]+), end ([0-9]+\.[0-9]+)/-i \"$SOURCE.$EXT\" -vcodec copy -acodec copy -ss \2 -to \3 \"$SOURCE-\1.$EXT\"/" |
xargs -n 11 ffmpeg

  • ffmpeg brew yasm

    16 juillet 2013, par Johann

    I'm trying to install ffmpeg via brew. It error I get with yasm is

    "Error : You must `brew link pkg-config yasm' before ffmpeg can be installed"

    When doing so I'm told that my permissions are insufficient.

    "Linking /usr/local/Cellar/pkg-config/0.28... Warning : Could not link pkg-config. Unlinking...
    Error : Permission denied - /usr/local/share/doc"

    The permissions are -rw-rw--- . I've tried unlinking yasm package and then redoing it with no luck. Any ideas ?

  • How to use ffmpeg to encode multi-channel video ?

    13 juillet 2018, par Leo

    Like nomral video have RGB/YUV, 3 channels.
    Is it possible use the existing video convertor to encode more than 3 channel video ? (e.g. given 5 folders of the same number and resolution pictures, generate a 5-channel video from them)
    I not need to playback the 5-channel video, which is impossible for 3-channel display. I just need to encode it and then decode it back to images. Actually what I am looking for is not a playable video format, I am trying to compressing several similar video content into one file, so that hopefully they can share the motion vectors and save more space.

    Dose any existing video codec support this manipulation ? Or how should I rewrite some part of the exsiting video codec(some light weight implementation of H264) to support it ?
