[FFmpeg-user] About timestamp

[吴斌斌]

Roger Pack:
thank you, but more confused now.
I've tested "*ffprobe -show_packets **"for a few files, all of their video
stream's pts/dts step differed.
Here are my files:

> 1. i_15bis.ogg=====theora&vorbis=====video_step:1&audio_step:N/A
> 2. oceans-clip.webm=====vp8&vorbis====video_step:42&audio_step:23
> 3. oceans-clip.mp4=====h.264&aac=====video_step:1001&audio_step:1024
