Hey Derek, tested this patch and it seems to work well, P247.

Though this allows some odd combinations (which fail), such as MPEG4 & Theora.

@ideasman42 there are way to check and query if combination could work. Not that the ffmpeg api is super easy but it could be made to allow more combinations of settings and actually check. The question is more what do we want to support ? By allowing more we potentially increase number of issues we can expect.

@MartijnBerger, IIRC the issue here is FFMPEG is capable of writing container/codec combinations which it can read but aren't in common use elsewhere.
So we may have to have some hard-coded list of combinations.

Majority of compatibility checks in FFmpeg is done at encoding runtime without any way to know this a-priori. Also, even existing interface allows you to setup encoding in a way which is not supported by FFmpeg.

Since mp4 and h264 is quite rather really common combination (we used it for Gooseberry youtube video i.e. since it's recommended format) i'll just suggest go ahead and enable that combination in blender.

Sanity checks is nice to have, but could happen later as well.
