RAW blu-ray 264 video stream to MP4 ? Problem

[scoobdriver]

I have a HD raw 264 video stream from a blu-ray rip that I'd like to mux to a MP4 format, I have converted the AC3 to AAC mp4.
I can play the raw 264 stream via VLC, or PowerDVD.
When I mux it with the audio to a mp4 format with YAMB, MP4box, the resulting files does not play properly I can hear the audio but the picture is all messed up, just strips of artifacts and colour..

has anyone any ideas why ? I have heard something about key frames.. what is this ?

Thanks in advance..

Post all the details from the h264 stream and mp4 stream after muxed. Use MediaInfo.

Does this help at all ?

I can't see why it wont work.

Try also play with mpc-hc and smplayer and see it make any difference. And try mux using ffmpeg(command line tool, google ffmpeg mux and you will see how to type) or mp4muxer.

[scoobdriver]

Yeah,

O.K so I tried MP4muxer with simlar results... really confusing me as both streams seem to be playable before muxing into MP4 container...

Something is very strange....

Somehow things are corrupting when muxing, if I play the resulting file sometime I will get the odd frame were I can see part of the picture otherwise it's just loads of blocks..

[poisondeathray]

Did you specify frame rate when muxing? What happens when you mux video alone (without audio)?

Also check if other containers have this problem, this may provide more information:
e.g. use mkvmergegui to put into an .mkv container
e.g. use tsmuxer to put into .m2ts or .ts

[scoobdriver]

hi yes i'm specifying 23.976..

I have muxed the video into a mkv file and this works..

Thanks
