[MPlayer-users] midentify fails to detect video parameters, bitrate and etc, on specific file

[Denys Fedoryschenko]

Hi

First of all, thanks for your great software. It is first one who was able to 
play and recode properly my Sony camcorder files (crappy Sony AVCHD). 

I face small problem with other things, filled bugzilla entry, but noticed in 
other reports recommendation to send mail to maillist. Here is my problem:

I have a file, where midentify will fail to detect correct parameters.
I am not sure it will cause playback problems, but probably it will be nice to
show proper result in midentify.
I am using mplayer as tool to retrieve video/audio parameters from video files
on my embedded box to make some kind of catalog. Tested on svn version of 
ffmpeg (to build shared libavcodec), and git version of mplayer and tested 
there.

Also i test on latest ebuilds of mplayer on gentoo with x264 library enabled,
it gives same results.

mplayer with debug output from gentoo
mplayer -vo null -ao null -frames 0 -identify -v /work/00001small.m2ts
