Hi all,

I have a transport stream with h.264 video in it captured from german Premiere HD channel. I've demuxed the raw h.264 stream from is using h264tsto and then muxed to avi using avc2avi.

3 problems occured (i managed to solve 2 of them):

1. Wrong resolution was set in the avi header. 1920x544 instead of 1920x1088. This problem was already known to me, so I just corrected it with WinHEX

2. VirtualDub had to reconstruct the missing index block

3. When reconstrucing the missing index block I also checked the option to re-derive keyframe flags and here is the problem I cannot resolve, namely the keyframes are not set, so I can't skip between key-frames in VirtualDub.

I ain't a big problem, cause the the file plays well, but it kinda annoying me :)

Hi Maxiuca,

all 3 problems are solved in the modded version of avc2avi. See this thread (http://forum.doom9.org/showthread.php?p=866145#post866145) for the download address. Premiere HD works fine with it. There were issues with BBC HD which I have also solved. I am currently in testing and will release the new version soon.

Thank you very much for the anwser. I've searched for the answer before posting but haven't found the answer. Seems I have to improve my searching skills :)

I'll test it on SkyUK streams and post results in the other thread.

Course you could solve this by muxing the raw h264 into mp4 then muxing that into a mkv file with the sound. The mkv container is much better compared against avi which is more of a kludgy hack.

Yes, I too don't see the point in muxing H264 to AVI...:confused:

I think this has been discussed thousend of times. MP4 ain't good cause you can't mux ac3 into it (without any hacks). MKV is a fantastic container and I do use it and I will probably mux this stream along with the audio to matroska in the end but for now I need it in avi container. Matroska with all its advantages has one big disadvantage, cause it's not widely supported in both commercial and free/open/shareware apps.
