How can I obtain the dimensions of a Flash video file from PHP code?

Question

I have an application where users can upload video files of any size, and I'd like to be able to determine the the height/width of a Flash video file (flv or f4v) from a PHP script so that I can size the player appropriately. I'd love a pure PHP solution, but I'd be open to shelling out to a command line tool and parsing the output (if such a tool exists).

Thanks in advance!

Answer 1

ffmpeg is probably your best bet, there is even a php module of it.

ffmpeg -i "FileName"

Alternativly you could read the information from the flv file directly by opening the file and reading the meta information.
