i have posted this already on the xvid maillist and pointed to this thread, so some xvid devs hopefully read this and fix it, as if its the case, its definitely a xvid bug

Hmm. Yes, thats what I thought. However, the only thing in the user data is XviD0038. Which must mean that the build I used was before these changes from suxen_drol for DXN compatibility were checked into the cvs. Which is really peculiar since, there must be something else wrong with these files. I guess I could try to add DivX503b1393n to the user data and see if that helps.

i found that its very likely that the custom matrix streams nerodigital produces in reality dont use custom matrices, but simply mpeg quantisation
thats why the players played the nerodigital "custom matrix streams", but not the ones created with xvid in mp4

Hi, I created a file yesterday to play in my player. Here are the features I used:

Cinema Plus NTSC (Uses VBV)
H.263
B-frames 2
Qpel
VHQ 4 + Bframe VHQ
Trellis
Stereo LC AAC audio
Muxed with YAMP w/ chapters and soft subs

Anyway, the stream does not play in my player properly. I suspect the reason for this is that the Cinema Plus Profile does not allow you to not use packed bitstream. I have requested in the past for XviD to allow setting VBV values in the unrestricted profile. It stutters. Perhaps I'll try unpacking the bitstream and trying again. I will also make a feature request for VBV in unrestricted profile in XviD.

Update. I extracted the video from the mp4 and it seems it is not packed. Does mp4box detect that the avi is packed and unpacks it? So I dunno what is wrong. Everything I used should be compatible.

Yes, MP4Box/YAMB is able to detect packed bitstream in AVI and remove it before muxing into MP4...

Are you ableto generate a 10MB (or less) sample an e-mail it to me please?

Cheers

Yes, I can do that. I should be able to get you a 3-4MB file.

Update: Ok sent

Hi BoNz1,

When I tried playing your sample in the my Zensonic Z500 it would not play either!

However, after de-muxing the streams with YAMB I was able to individually play the "video" and "audio" streams without any issues. So this would suggest it's the TTTX subtitles that are causing the problems.

By design NeroDigital Certified players support VOBsubs

Cheers

SMD, yep that sounds quite possible. I will remove the TTTX subs and try again today.
EDIT: Yeah that was the problem. Thanks it works now.
