ffmpeg copyts to preserve timestamp
13 avril 2015, par BalaI 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.tsThe start_time value is delayed about 2 seconds consistently.
