Getting video dimension / resolution / width x height from ffmpeg

Question

How would I get the height and width of a video from ffmpeg\'s information output. For example, with the following output:

$ ffmpeg -i video.mp4         


        

Answer 1

Have a look at mediainfo Handles most of the formats out there.

If you looking for a way to parse the output from ffmpeg, use the regexp \d+x\d+

Example using perl:

$ ./ffmpeg -i test020.3gp 2>&1 | perl -lane 'print $1 if /(\d+x\d+)/'
176x120

Example using python (not perfect):

$ ./ffmpeg -i /nfshome/enilfre/pub/test020.3gp 2>&1 | python -c "import sys,re;[sys.stdout.write(str(re.findall(r'(\d+x\d+)', line))) for line in sys.stdin]"

[][][][][][][][][][][][][][][][][][][]['176x120'][][][]

Python one-liners aren't as catchy as perl ones :-)
