Question

Support for H.263 and MPEG4 codec.

dreamaniajp opened this issue 4 years ago · 6 comments

Hi, current mp4parse doesn't support H.263 and MPEG-4 codec.
May I know if there is a plan to support these two codecs?
Or if you may accept that kind of contribution?

Thanks a lot.

Support for demuxing different data is usually driven by users of the lib contributing support. Firefox is a big one of these, and my understanding is that there's not a big use case for H.263 at this time. When you say MPEG-4 are we talking MPEG-4 Part 2? If so I think that would be in a similar boat.

If someone where willing to add support for those I don't see why it wouldn't be accepted.

Hi, I've filed a PR for H.263 support. #245
May I have someone's help to review?

Thanks a lot!

Thanks! I'm not super familiar with the H.263 packing, so am going to check the specification and will follow up with any questions on that PR. If you know the relevant specs it would be appreciated if you could point them out so I don't overlook any of them.

Thanks!
The specification could be found on ETSI site.
The latest one I could find is

Thanks a lot!

Does #245 resolve this, or is there additional work to do?

I assume this is done. Please reopen if not.
