  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Truncated prog_index.m3u8 in fluent-ffmpeg

    10 juillet 2020, par Hassnain Alvi

    I am creating a master playlist using fluent FFmpeg but the result prog_index.m3u8 contains last few entries it doesn't include full playlist data

    


    Here is the code for generating playlist

    


    const bitrate64 = ffmpeg("file.mp3").audioBitrate('64k');
    bitrate64.outputOptions([
        '-preset slow',
    '-g 48',
    "-map", "0:0",
        '-hls_time 6',
        '-master_pl_name master.m3u8',
        '-hls_segment_filename 64k/fileSequence%d.ts'
    ])
    .output('./64k/prog_index.m3u8')
    .on('progress', function(progress) {
        console.log('Processing 64k bitrate: ' + progress.percent + '% done')
    })  
    .on('end', function(err, stdout, stderr) {
        console.log('Finished processing 64k bitrate!')
    })
    .run() 


    


    Here is the output from prog_index.m3u8

    


    #EXTM3U
#EXT-X-VERSION:3
#EXT-X-TARGETDURATION:6
#EXT-X-MEDIA-SEQUENCE:1221
#EXTINF:5.990756,
fileSequence1221.ts
#EXTINF:6.013967,
fileSequence1222.ts
#EXTINF:5.990744,
fileSequence1223.ts
#EXTINF:6.013967,
fileSequence1224.ts
#EXTINF:5.953600,
fileSequence1225.ts
#EXT-X-ENDLIST


    


    when I run this command manually I get full index file but not with FFmpe. All .ts sequence files are correctly generated but. prog_index is not updated accordingly

    


    Can anyone tell me what I am doing wrong here ?

    


  • matroskaenc : write correct Display{Width, Height} in stereo encoding

    22 octobre 2014, par Vittorio Giovara
    matroskaenc : write correct DisplayWidth, Height in stereo encoding

    should be the raw amount of pixels (for example 3840x1080 for full HD side by
    
side) and the DisplayWidth/Height in pixels should be the amount of pixels for
    
one plane (1920x1080 for that full HD stream)."
    

    So, move the aspect ratio check in the mkv_write_stereo_mode() function
    
and always write the embl when stereo format and/or aspect ration is set.
    
Also add a few comments to that function.
