drop frame m2v

[bouis]

Is there a quick way to identify an m2v file as drop frame?

you can use BBVINFO.EXE from the bbtools package.

run it on your m2v/mpv file like so:

bbvinfo.exe filename.m2v 3 > check.txt

you can hit ctrl+c after a few seconds and then just parse the check.txt file till you see something like:


group_start_code = 0x000001B8
drop_frame_flag = 0


1 for drop, 0 for non drop

-Cheers.

bbvinfo.exe filename.m2v (3?) | grep drop_frame_tag | less

Thanks.
