Is there any good way to get the resolution of a video file? For jpegs ImageMagick has the "identify" command which works really well, I'd like to have something similar for movies, particularly flv files. Currently I use the below shell script which is ugly but works, unfortunately it flashes up an X window and probably doesn't work if you aren't using X. #!/bin/sh while [ "$1" != "" ]; do echo q| mplayer $1 2>&1|grep ^VO.*x11| sed -e s/\ =.*$// -e s/^.*\ // shift done -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

I use this script that comes in the Mplayer source: http://dl.dropbox.com/u/2643992/midentify.sh It pulls out most all of the media metadata and displays it in a way re-usable for shell input. It also doesn't actually play the media, so no pop-ups for 1 frame. hannah

Thanks for that tip. It turns out that it's in the Debian package but for some reason they put it under /usr/share/mplayer/ instead of /usr/bin. So when looking for mplayer binaries I missed it but when looking for what happens to the midentify.sh script it was easy to find. I considered filing a Debian bug report, but there are plenty of open bugs against mplayer so it's probably not worth doing. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

I'd use mediainfo, for both video and image files. mediainfo filename.flv | grep -E "^(Height|Width)" Could also use a mediainfo template for customisable output.

Try avprobe, which in Debian can be found in the libav-tools package.

Others answered the real question, but re that immediate issue, there is -vo null -ao null. Handy when "watching" youtube where the video mux is just some guy standing in front of a camera.
