Yes, please. I need to be able to duplicate your issue.

Hmm, big thread is big, what is the correct method to cut a sample from the TS?

You can split it into pieces using DGSplit, for example.

Is setting start and end points in DGAVCIndexNV and then choosing "Save and demux video" a good way to get a stream sample? (the problem is reproductible with a stream obtained that way.)

Certainly, that is fine if it allows me to duplicate your issue. Please provide a link to the stream and the script and instructions for duplicating the issue. I'm very keen to address issues with random access, as it is the raison d'etre of the DG tools. Thank you for your willingness to help with debugging.

Create DGA file normally, then make an AVS script like this:

Code:
DGAVCDecodeNV_AVCSource("blah.dga")
Trim(90, 0)
and open in VDub.

(EDIT: Note the key point is accessing at frame 90, the problem does not happen with e.g. Trim(89, 0).)

Thank you.

The encoding is very unusual and I'm not yet sure it is fully legal. Where did this stream come from?

Original Japanese Blu-ray.

Interesting. The POCs are goofy in the stream (i.e., wrong) and I'm tempted to simply say that the stream is wrong. But there is a way to fix it. Instead of looking at the POCs of the first two pictures of the GOP to decide if it is open, I can look at the picture types. I've tried it and it fixes the problem so I'll probably go with that. I'm porting the AV sync fixes and I'll include this with the next release if it doesn't break anything else.

Other small question: is it safe to work on a DGAVCDec (non-NV) script in VDub while there is a DGAVCDecNV script encoding?

As long as you are working on different files. You wouldn't want to rewrite the DGA file while the decoder is using it.

I have fixed this problem. The fix will be in the next release

BTW, is it possible to give these appropriate names, i.e. DTS Master Audio, TrueHD?
If someone can tell me how to detect those audio types, I can probably do it.

This is with m2ts container, right? If so, you can use the stream type:

Code:
0x03: MP2 (MPEG-1 Audio Layer II)
0x04: MP2 (MPEG-2 Audio Layer II)
0x0f: AAC (MPEG-2 Part 7 Audio)
0x11: AAC (MPEG-4 Part 3 Audio)
0x80: LPCM (only if format id descriptor is 'HDMV')
0x81: AC3
0x82: DTS
0x83: TrueHD+AC3
0x84: E-AC3
0x85: DTS-HD High Resolution
0x86: DTS-HD Master Audio
0x87: E-AC3
0xA1: E-AC3 (secondary audio)
0xA2: DTS Express (secondary audio)

DTS-HD-HR into m2ts container:
http://www.mediafire.com/?sharekey=6...1f79f1876d365a

You will find the modified pcm by Pcm2Tsmu and raw pcm under the same folder. (audio.pcm is raw and audiopcm_out.m2ts is modified by Pcm2Tsmu)

Just for curiousity, neuron2, have you planned creating a GPU based decoder for H264 and VC1 for ATI cards, using ATI's stream API? I would be very interested in that and I assume a lot others who own ATI graphics cards.
