How to check Video file resolution ??

Searched around but could not find an answer on this.

Is there a way to check what the resolution of a video file is from the N900 itself ?
Using the Details menu option from File Manager doesn't show it.
Maybe another App ?

Using mplayer and xterminal:

Code:

mplayer -identify file.avi -ao null -vo null -frames 0 2>/dev/null | egrep "(ID_VIDEO_WIDTH|ID_VIDEO_HEIGHT)"

Might be something wrong with my mplayer install. I get this as the output:

# mplayer -identify tgwtdt.avi -ao null -vo null -frames 0 2>/dev/null

MPlayer SVN-r30099-4.2.1 (C) 2000-2009 MPlayer Team
ID_SIGNAL=11

With no special options I get this:

# mplayer -identify tgwtdt.avi

MPlayer SVN-r30099-4.2.1 (C) 2000-2009 MPlayer Team

MPlayer interrupted by signal 11 in module: unknown
ID_SIGNAL=11
- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.

Code:

$ file video.avi

(doesn't work with .mp4 - does with MPG/AVI)

here it works!
I have the same version of mplayer.

But I found out that grepping "VIDEO:" and "AUDIO:" shows more informations!

So I made a little script called identifyVideo.sh with this contents:

#!/bin/sh
mplayer -identify "$1" -frames 0 -ao null -vo null 2>/dev/null | egrep "VIDEO:|AUDIO:"

Whats the path to the 'file' command ?
I only have filebox and filefrag.

I think you need to 'sudo apt-get install file' first

Does your mplayer work at all?

Code:

mplayer /path/to/anyvideofile.avi

would play the file and display video/audio info.

OK, I worked it out. The mplayer command doesnt work when running it as root. Running as normal user shows the video file details.
Silly me.
