How can I get the resolution (width and height) for a video file from a linux command line?

Question

I\'ve been digging through the mplayer/mencoder and ffmpeg documentation and I can\'t seem to come up with anything. I\'m not especially picky as to the out

Answer 1

Try midentify.sh (TOOLS/midentify.sh in the source code tree of MPlayer).

It will show information in a parseable format:

$  ./midentify.sh /data/myvid.flv 
ID_VIDEO_ID=0
ID_AUDIO_ID=1
ID_FILENAME=/data/myvid.flv
ID_DEMUXER=lavfpref
ID_VIDEO_FORMAT=VP6F
ID_VIDEO_BITRATE=0
ID_VIDEO_WIDTH=640
ID_VIDEO_HEIGHT=480

Answer 2

MediaInfo has a command line version and provides the dimensions together with tons of other information.

Answer 3

Here's an "almost-one-liner" I've concocted around ffprobe for exactly this purpose. Works pretty well for me both on Linux and MacOS.

#!/bin/bash

B='[[:blank:]]'
D='[[:digit:]]'
ffprobe "$1" 2>&1 \
    | grep 'Stream.*Video.*fps' \
    | sed "s/^.*$B\($D$D$D*x$D$D$D*\).*$/\1/"
