[FFmpeg-user] 回复： incorrect fps and tbr

[qw]

Hi,

I know the function of ffprobe

>Input #0, avi, from '6_F16_DUAL_AB[WisMencoder Encoded].avi':

But You can get the duration of whole file, but not the duration of each track. There are one or more tracks in  mp4 file. The duration of tracks maybe different. How to get the duration of each track?


Thanks!


B.R.
