No real harm done, ans sorry for the harsh tone. Your initial message has this: >>> In-Reply-To: >>> <cae6_u_rtud6z-kd1fidfaz6_zo6fhlfvrv_nw7vqb2a0pum...@mail.gmail.com> That means you wrote it by replying to this message. > The capture I'm doing is v4l2 to nvenc to matroska. Then frames have timestamps provided by the kernel: ffprobe -i /dev/video0 -of compact -show_packets [...] packet|codec_type=video|stream_index=0|pts=1392045174616|pts_time=1392045.174616|... As you can see, this is the monotonic clock (and my uptime here is 16 days), but lavd can convert for you: http://ffmpeg.org/ffmpeg-devices.html#video4linux2_002c-v4l2 With that, you just need to do whatever you want with the timestamps. By default, ffmpeg will normalize the timestamps before any filtering or encoding, but you can disable that with the "-copyts" option. Regards, -- Nicolas George
