How can I get the resolution (width and height) for a video file from a linux command line?
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 output format as I can use a regular expression to pull it out, I just can't seem to get the data in the first place.
Answer
Use ffprobe (part of FFmpeg toolkit)
example:
ffprobe -v quiet -print_format json -show_format -show_streams ~/Movies/big_buck_bunny_720p_5mb.mp4
output:
