  • How can I extract bonus images from a tv show DVD using ffmpeg ?

    5 avril 2020, par Hatem

    I'm using MakeMKVcon to automate episodes extraction. It do the job, expect the metadata. I have to rename files manually. But the problem here is that I want to extract some bonus pictures slideshow from the ISO but no software can detect it. I can only display those images using VLC (using the ISO file).

    



    Do you have any idea how to do that ?

    



    Here's the ffmpeg -i output :

  • Compiled FFmpeg not accepting -c:v and -c:a

    13 mars 2020, par King Horse

    I compiled FFmpeg with libsrt, with the online compile guide. https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu & how to compile ffmpeg with enabling libsrt

    It seems to compile correctly.

    ffmpeg version N-96575-g843c24a Copyright (c) 2000-2020 the FFmpeg developers
    
built with gcc 7 (Ubuntu 7.4.0-1ubuntu1~18.04.1)

    But when running this command to convert a incoming SRT stream to HLS, it doesn’t know the -c:a command. When switching the order, it runs that it doesn’t know about the -c:v command.

    ffmpeg -re -i srt://0.0.0.0:25000?pkt_size=1316&mode=listener -c:a copy -c:v copy -strict -f hls -hls_time 4 -hls_playlist_type event stream.m3u8

    I have searched the issue, but I could not find anything similar.
    Does someone know what I have missed in the setup ?

    Everything is manually compiled through the guide, this was the final command I run to compile FFmpeg :

    cd ~/ffmpeg_sources && \
    
wget -O ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2 && \
    
tar xjvf ffmpeg-snapshot.tar.bz2 && \

  • avformat/mov : check that pcmC box is of the expected type

    4 février 2023, par Jan Ekström
    avformat/mov : check that pcmC box is of the expected type

    As per 23003-5:2020 this box is defined as
    
PCMConfig extends FullBox(‘pcmC’, version = 0, 0), which means
    
that version is 0 and flags should be zero.
