Hi,
I always use "mplayer filename -identify -ao null -vo null -frames 0"
to get the information of a video file. But, I found mplayer can't get
the correct duration of a Sony DV MTS file(ID_LENGTH=0.00) while the
"ffmpeg -i MTSfilename" can get the correct duration time. I compiled
the mplayer from lastest svn source.
My question is:
Why "mplayer" can't get the correct duration time of a MTS file?
How to get the duration(ID_LENGTH) of a Sony MTS video file use
"mplayer"?
Thanks.
PS:
Below is the command output(mplayer, ffmpeg, mediainfo, please tell me
if need sample file):
