Changing Frame Rate

[Peter Maersk-Moller]

Hi ht Techdev.

Couple of things.
1. num-frames should be num-buffers in your example.
2. Using filesink to save into a file with the extension mp4 does not make
it a file using the mp4 containerforat. You need to add a mp4 muxer. What
you are saving is a raw h264 stream.
