    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.

  • ffmpeg copyts to preserve timestamp

    13 avril 2015, par Bala

    I am trying to modify an HLS segment transport stream, and preserve its start time with ffmpeg. However the output does not preserve the input file’s start_time value, even if -copyts is mentioned. Here’s my command line :

    ffmpeg  -i fileSequence1.ts -i x.png -filter_complex '[0:v][1:v]overlay[out]' -map '[out]' -map 0:1 -acodec copy -vsync 0 -vcodec libx264 -streamid 0:257 -streamid 1:258 -copyts -profile:v baseline -level 3 output.ts

    The start_time value is delayed about 2 seconds consistently.

    /Users/macadmin/>ffmpeg -y -v verbose -i fileSequence0.ts -map 0:0 -vcodec libx264 -copyts -vsync 0 -async 0 output.ts
