  • What are the differences between FFmpeg and Libav ? [closed]

    16 septembre 2012, par Ken

    According to the first comment for this question, and i quote

    What are the differences that exist between this 2 projects ?

    I'm interested in video and audio encoding to H/X264, Mp3 and AAC with Mp4/Mkv containers ; but more importantly i would like to start with a reliable and up to date library with a permissive license and widely supported on as many platforms as possible.

  • FFmpeg how generate a sequence of videos with bash

    27 janvier 2018, par Massimo Vantaggio

    i try to write an .sh that read a folder create a playlist of mp4 files and then generate an only big video with a sequence of all videos find in the folder, and encode it for dash :

    printf "file '%s'\n" ./*.mp4 > playlist.sh
    
ffmpeg -f concat -safe 0 -i playlist.sh -c copy concat.mp4

    Till now i follow the demux concat official guido to ffmpeg website.
    Without result, also the following give me "more than 1000 frames duplicated between videos of the sequence"

    ffmpeg -f concat -i playlist.sh -c:a aac -b:a 384k -ar 48000 -ac 2 -c:v libx264 -x264opts 'keyint=50:min-keyint=50:no-scenecut' -r 25 -b:v 2400k -maxrate 2400k -bufsize 1200k -vf "scale=-1:432 " out.mp4

    8 novembre 2022, par user1722669

    I was trying to use FFmpeg and libx265, but actually, I can't find any working solution for HEVC and Constant bitrate

    



    *ffmpeg -i "D:\video\Mixer test.mp4" -c:v libx265 -x264-params "nal-hrd=cbr:force-cfr=1" -b:v 1M -minrate 1M -maxrate 1M -bufsize 2M output.ts*


    



    or

    



    ffmpeg -i "D:\video\Mixer test.mp4" -c:v libx265 -preset medium  -pass 1 -b:v 5000k -preset 5 -x265-params -strict-cbr -crf 28 -c:a aac -b:a 128k output.mp4


    



    Is it possible to get CBR with h265 ?

    



    If it isn't possible can you share some official information about it

    



    Thank you.
