Hi all. I need a shell command to output the resolution of a video file for use in a script but I'm at a loss. Can anyone help me.

# xdpyinfo | grep '^ dimension' | awk '{print $2}'

I'm a relative noob but it look like this code will query a display server? What I'm wanting to do is query a file.

I don't know of a tool which does this, but I know some programs use mplayer to create thumbnails of video files. If you could use mplayer to output a single frame at the resolution of the video, you could then use a tool like identify (from ImageMagick) to get the dimensions of the frame.

If all your videos are in a single format, you may be able to use another tool, but if you have to deal with videos in arbitrary formats, you will need to use a movie player somewhere.
