VC-1 Direct Show Filter Issue

[Ryu77]

I was attempting to back-up my Blu-ray copy of Earth and noticed that during certain scene changes there seemed to be a (VC-1) decoding issue. To me it looks like a B-Frame or an I-Frame wasn't decoded correctly.

ArcSoft TotalMedia Theatre plays these same sections without any issue at all, as does my PS3. However, when I play this through any Media Player that calls on Direct Show (Windows Media Player, Media Player Classic etc.) the issue is present.

Here is a 8 second sample cut directly from the original. The issue happens just as the scene changes...

All I want to be able to do is create a backup without these errors. I have tried creating a filter graph via GraphEdit and I seem to be running into problems. The Cyberlink VC-1 decoder wont connect and the Sonic HD decoder connects but when running the AVIsynth file this error message appears... "DirectShowSource: GRF file does not have a compatible video pin. Graph must have 1 output pin that will bid RGB24, RGB32, ARGB, YUY2 or YV12".

I am trying to find a way to use any other decoder than the WMVideo Decoder DMO. As that is the default decoder that seems to be causing the issues. Any ideas?

Works fine with DGVC1DecNV.

Damn! I was looking for a VC-1 DG tool via Google, for some reason nothing came up. Thank you!

Thank you for the tip Neuron2...

I seem to be getting a "missing license file" error.

I am running a 9600GT as listed under supported GPU's. I have also copied the nvcuvid.dll as instructed to my "C:\Windows\System32" directory.

Is there anything else that I need to do? I am attempting to open a M2TS stream. Do I need to demux, and open the VC-1 elementary stream?


Edit: It's ok, I found the answer with a bit of searching. So your software is commercial now? I hope you have considered following the correct laws that enable you to sell your software as it is not freeware anymore. I am sorry but I can not justify $15 for one backup. I have had no other issues with VC-1 decoding previously. This is the first time it has happened. If I had more use for it, I definitely would. I have been happily using your dgmpgdec tool for many years.

Ryu77 - if you repackage the .m2ts in .mkv using eacto, the decoding issue disappears in your sample using WMVideo Decoder DMO

I've seen something like this before with both AVC and VC-1 streams, where the container sometimes has an effect on proper decoding, I can't explain why

[Ryu77]

Wow! It actually worked...

I just repacked it with MKVMerge. I wonder why this happens :confused:... Anyway, thank you. :)
