  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • How to add album art with ffmpeg ?

    8 février 2024, par Adi Ricky k

    I've been stuck in adding album art to mp3 files.

    


    I've already researched and Googled this issue but haven't found a solution yet. The ffmpeg documentation recommends this script to add image (album art) to mp3 :

    


    ffmpeg -i input.mp3 -i cover.png -c copy -map 0 -map 1 -metadata:s:v title="Album cover" -metadata:s:v comment="Cover (Front)" out.mp3


    


    But it doesn't work. My console output is :

    


    Unrecognized option 'c'
Failed to set value 'copy' for option 'c'


    


    I looked for another solution and got this :

    


    ffmpeg -i input.mp3 -i cover.png -map 0:0 -map 1:0 -c copy -id3v2_version 3 -metadata:s:v title="Album cover" -metadata:s:v comment="Cover (Front)" out.mp3


    


    This returns the same output :

    


    Unrecognized option 'c'
Failed to set value 'copy' for option 'c'


    


    Anybody can help me, please ?

    


    I am using ubuntu 12.04 and ffmpeg version 0.8.6-4:0.8.6-0.

    


    Thanks.

  • duration change after transcode ts

    25 décembre 2017, par Feilong Luo

    i have a problem about transcode with ffmpeg

    i want to cover m3u8 to mp4, so i transcode every ts file first, and then concat them to a mp4, but i found that the duration will be bigger than source file.

    source file is :
    http://oc7iy3eta.bkt.clouddn.com/src_20.ts

    after transcode, test file is :
    http://oc7iy3eta.bkt.clouddn.com/test_20.ts

    i use the command as bellow to change to 5fps, and 400k bitrate :

    sudo ffmpeg -analyzeduration 2147483647 -probesize 2147483647 -nostdin -y -v warning -i ./src_20.ts -threads 3 -movflags faststart -metadata:s:v rotate=0 -chunk_duration 520000 -video_track_timescale 25000 -pix_fmt yuv420p -copytb 1 -vcodec libx264 -b:v 400000 -minrate 400000 -maxrate 400000 -bufsize 500k -force_key_frames "expr:gte(t,n_forced*2)" -vsync 1 -r 5 -s 544*960 -acodec libfaac -async 1 ./test_20.ts

    i use ffprobe command to see video info :

    source file info :

    Duration : 00:00:01.26, start : 28.346989, bitrate : 921 kb/s
    Program 1
    Metadata :

    service_provider : FFmpeg

    test file :

    Input #0, mpegts, from ’test_20.ts’ :
    Duration : 00:00:01.62, start : 1.576778, bitrate : 447 kb/s

    Stream #0:1[0x101] : Audio : aac ([15][0][0][0] / 0x000F), 44100 Hz, stereo, fltp, 5 kb/s

    =======================================================================
