Attached a .rmvb (rv40, cook) file where MediaInfo reports a av delay of 0, when I run ffprobe -show_packets "path to file"
and look at the first few packets I get the following -> http://pastebin.com/hS54XNX7
main point is that the video stream starts at:
and the audio starts at:
so I delay of 1101ms is probably the right info (seems to work fine on remuxing)
Ps.: I understand that rmvb is not the most popular format, but I thought reporting the problem shouldn't hurt.
