Does anybody know a ready-made, reliable way to tell the dimensions (width x height) of a MP4 encoded using the H.264 codec without ffmpeg or similar extensions, in pure PHP?
Thanks for all the answers folks. The bounty is running out and I will not have time to check the offered solutions before it does. I will accept the solution that I feel has the greatest likelihood to work.
It sounds like http://code.google.com/p/php-mp4info/ might be your answer. It reads MP4’s but it doesn’t mention anything about H.264.
also, what OS are you using?
