DGMVCSource

This is something that could be fun to work on. But does Intel Media SDK require Haswell with QuickSync and all that? I have only i7 980X Gulftown at this time.

If I made it I would release under suitable re-usable license, not like DGDecNV.

Seems now it requires also Win7 which makes thing difficult for me at this time. Maybe it's time for me to get into the current century.

EDIT: The current DGMVCSource version will always be linked here:

Thanks for your help. I don't know the exact requirements, but Win7 is probably one, yes. Are you still under XP only?
I don't think the Intel decoder requires special hardware. It can run with hardware optimisation on specific Intel hardware, but it should run without problem on any CPU.

Sadly, yes. I was planning to upgrade OS at my next hardware upgrade. May be time to accelerate that. It's not so easy to upgrade existing systems, as I'm sure you know.

Perhaps could you make a VM with VMWare Player ?
It's what I do when I need

Started shopping for my new system.

It will enable me to consider this project and also QuickSync support for DG tools.

Excellent news, Neuron2! I wish you all the best with your new system. :-)

I will do my best not to disappoint you.

That one (QuickSync for DGDecNV) will be licensed like DGDecNV, however, while an MVC source filter will be fully open. Don't hate me.

The MVC source filter will be open. QuickSync for DGDecNV not. I hope it is clear and I edited my post to clarify.

While I wait for delivery can anyone point me to, or place here, a concise and complete specification for what the source filter must do? I confess to having little experience in the area of MVC, although obviously I have a lot of experience creating source filters.

I have tried to describe what the current MVCSource plugin does here.

To summarize, the decoder should ideally be able to take the two demuxed video streams as input (AVC and MVC), and output a single interleaved stream with one frame from one stream followed by one frame from the other stream, and so on. The order of the images (AVC in odd and MVC in even frames or vice versa) must be controlled by a parameter. (Alternative outputs such as side by side or top & bottom combined frames can be considered if you wish, but since avisynth has the possibilities to build them from the interleaved stream, it's not necessary.)

As far as I know, the Intel example CLI command requires a single "combined" AVC+MVC video stream as input. I don't now if the library has the same limitation, but I suppose not, since the current MVCSource plugin can accept the 2 streams. (It can also accept a combined AVC+MVC single stream, but, unless it's easy to do, I don't think it's an useful feature.)

The current plugin can also decode and output the AVC stream only (but it is easy to decode it with other Source commands), or the MVC stream only (more useful, but not really necessary). It can also enable the hardware acceleration feature of the Intel library, but I suppose that that part can be added later, and I'm not sure it is really useful, as I don't know if the required hardware is frequent.

There is currently no audio support in MVCSource, and I don't think we need it.

Of course, it would be nice if the plugin could also accept a MPLS (or SSIF) file as input, but that requires probably some kind of demuxer, and I suppose it's a difficult and long work.

Another feature that is currently missing and that could be a very great improvement is some kind of seek support. Currently, all frames must be decoded sequentially. Not a big deal.
