DGVC1DecNV Version 1.0.6

Guest · 22nd November 2008, 01:59

DGVC1IndexNV today decoded its first VC1 stream from the blu-ray "Baraka". I'm still some time away from being able to release an alpha, but I wanted to start this thread to let you know about it and to ask for some test clips.

I'm looking for any and all VC1 clips, but only raw elementary VC1 or in an M2TS container. I will do ASF later. Thank you.

For those not acquainted with my tools, the NV on the end denotes a version that runs on an Nvidia graphics card GPU. I don't have any plans to develop a non-NV version because I am not aware of any decent open source decoder.

Also please be aware that my NV tools require a license obtained by making a small donation to become a supporter of neuron2.net.

EDIT: This post will now hold a link to the latest version.

Thanks, Snowknight26. It plays just fine.

What GPU did you use for decoding?

Guest · 22nd November 2008, 15:11

I used both 8500GT and 9600GT.

Officialy those two cards don't support VC-1 full bitstream decoding. Or maybe nVidia updated the VP2 core

I need to go through my blu-rays and see whats vc1.

I'm keeping a close eye on this one, as it'll help me justify whether I purchase a new graphics card for Xmas.

Hopefully this works. Here is the procedure I followed to create this file.

1.) Source is evo container from HD DVD
2.) Extracted VC1 and E-AC3 using eac3to
3.) Muxed VC1 and E-AC3 to M2TS using tsMuxer

It's not working. Can you please post a sample of the extracted VC1 from step 2?

I'n not seeing a sequence layer in the m2ts.

Anyway, who cares about HD-DVD?

could it be because eacto removes the pulldown from hddvd vc1 files i think...

i suppose you could call your program DGblurayVC1DecNV

heres 3 files that should work:

Nah. The sequence layer is missing it seems. Or maybe it's simple or main profile VC1 in the EVO. That's why I want to see the demuxed ES.

Nah. It should work on all advanced profile VC1. Simple and main require stuff to be signaled out-of-band in the container, and if the demuxer doesn't recreate that as in-band syntax, then it goes to hell. At least that's my understanding. Again, that's why I'd like to see the demuxed ES.

Thanks for the samples. I'll report back only if they don't work.

I guess because all of the broadcast related stuff like PID, PAT and all the other things you need careful worked out parser logic for that (what do you parse?,when do you parse?,in which situations do you override bitstream values with container level values?)

There is no container for transport streams, there is only the bitstream.

CruNcher · 23rd November 2008, 23:55

Of course you right, for transport stream every Video related decision is left @ the bitstream level and it's flags, it would only count for the other most used formats

Maybe in bob0r example the problem of not being able to parse those files is caused by missing PAT/PMT or not able to find the correct PID ?

Could be. If he would post one, I could determine that.

@neuron2: Is there any possibility of a merge of DGVC1DevNV and DGAVCDecNV into one program, possibly when both are more mature?
