How do I extract video information from a H.264 .TS file?
Is there any good linux/unix tool to get the properties of an H264 .TS file?
I need the duration, video resolution and bitrate, fps, audio resolution and bitrate.
I tried mplayer -vo null -ao null -frames 0 -identify _file_, but it reports wrong video width and height, and also reports the file length (duration) as 0.00.
Answer
You can run mediainfo (here) and parse its output.
mediainfo <filename> will give you this kind of information:
