Kind of vague title. Sorry for that. Here's a summary:

1. Using Yamb, I demuxed an avi file (h264 inside). I now have a raw h264 file.

2. Using Yamb with ANY mp4box build, I mux a raw h264 file into an mp4 container. The mp4 file just doesn't want to play with media player classic. The MPC window shrinks considerably in size and displays a very small box with a distorted whitish picture. Sometimes the file doesn't do anything. I just freezes.

3. But.....the raw h264 file plays just fine with MPC

4. I can mux the raw h264 into an mkv container using mkvmerge. The mkv file plays just fine in MPC.

The raw h264 file seems to be ok. It appears that Yamb (mp4box) is screwing up somehow.

That about sums up what I have been working with.

It's important that this file plays with MPC because when it works with MPC, it works with the xbox 360. My experience, anyway.

So what gives? Are there any alternatives to Yamb that I can try out for muxing an h264 file into an mp4 container?

Thanks

UPDATE:

I don't USUALLY have problems using Yamb (mp4box). But sometimes the occasional h264 file doesn't want to play nice with yamb. So I did a lot of searching/reading and tried various programs. I finally tried mp4creator. Worked like a charm on two different h264 files that yamb refused to work with. I simply muxed both video and audio files into separate mp4 containers. Then I used yamb to to mux the mp4 files. I was rather surprised and impressed. No audio sync issues. No problems at all. Anyway, maybe this can help someone in the future.
