VC-1 on SandyBridge iGPU, Win7, SageTV7: What are my options?

[dcardellini]

I never resolved this and embedded my question in a previous "too long and rambling post."

SandyBridge must be an important cost-effective low-power client for many here. The only thing I cannot do natively in Win7 on this hardware is stutter-free VC-1. (bluray mkv rips).

I would prefer a non-commercial codec, but would like to know all options.

Thanks for any help here.

LAV supports quicksync. Try that. It's free.

[dcardellini]

Yes, I have been keeping eye on this at avsforum, and it does look good.

Has anybody actually installed and used with SAGETV? Just want to know if I am entering a pain cycle, or if this road has already been paved.

Thx panteragstk!

[panteragstk]

I use it, but not with quicksync. I've used it with both cuda and dxva2. Both work except h.264 and dxva2. Every other codec works just fine though.

SageTV Client has big trouble with WM9/VC-1. I believe those who have solved the problem have resorted to re-clock.

panteragstk:

Not clear from your post...... are you getting smooth, stutter-free VC-1 in a client SageTV7 installation? If so, how?

I was getting smooth VC-1 in WinXP, SageTV6, and iGPU on AMD785g board, but without DXVA. Win7 and SageTV7 broke this for me due to breaking of Haali.

Korben_Dallas's post almost sounds like nobody is getting smooth VC-1 in my configuration. At this stage of maturity, I am pretty shocked that nobody watches bluray rips with VC-1 encoding, or at the least, there are not dozens of posts on this exact topic.

Help! Can't imagine going back to XP and SagetV6.

[panteragstk]

I get smooth vc-1 playback, but all of my files with vc-1 video are .mkv's. I have the internal sage splitter disabled via enablestreamdemux registry value in the frey technologies folder. If you are on 64bit windows it will be in the wow64 section.

I never got smooth playback with the sage splitter.

panteragstk,

You seem to be one of the most experienced at getting a working SageTV video decoding. Would you be willing to author a post with all of your settings and installed codecs so that we can just copy and be happy about working SageTV. I have a Windows Server 2008 R2 SP1 x64 box that I want to migrate into the role of SageTV server plus client for one location. Do I have any hope of this box being able to play all my blu-ray based .mkv's?

thanks,

[panteragstk]

I have no clue if server 2008 will work or not. I'll try to create a post. I'm not that great at wording though. One thing is that not all settings work the same depending on the gpu in use. Most will, but not all.

Does this help - the Intel QuickSync Decoder released by Eric Gur an Application Engineer at Intel. This appears to work with ffdshow as well.

http://sourceforge.net/projects/qsdecoder/

[dcardellini]

That (Quicksync) looks like the best bet at this point for Intel SandyBridge iGPU.

How about commercial codecs? Can't I install PowerDVD or TMT and get the right codecs loaded that will allow sagetv7 to play VC-1 Bluray rips to mkv?

I spent a tremendous amount of effort getting all formats to play flawlessly on my AMD 785g iGPU......was kinda hoping I could ride this one out on someone else's back (lazy).

[panteragstk]

The issue with vc-1 isn't the decoder you are choosing. It is the sage splitter that doesn't play nice. I tried for a long time to get it to work and finally decided disabling the internal splitter and using gabest (mpc-hc) and converting to .mkv was a much better option.

[dcardellini]

OK....this is exactly what I want to do......play mkv VC-1 files.....so there is a solution!

In sagetv6, I am using MPCDecoder for VC-1 for this, with the Haali Splitter.

SageTV7 broke Haali. So what do I use in place of it?

Thanks for all your help here panteragstk!

[panteragstk]

It doesn't break haali, it just uses it's own splitter. If you have either gabest or haali installed it will use one or the other just fine once you disable the internal splitter.

[dcardellini]

wow....excellent!

I am out of country for next two weeks. As soon as I return, I will disable the internal and report my findings. Thanks panteragstk.

I can't find this registry value. Do you have to add it if it doesn't exist? I'm looking in: HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Frey Technologies\Common and it doesn't exist here or any of the sub folders?

This is an older thread about vc-1: http://forums.sagetv.com/forums/showthread.php?p=486013. You can disable the Sage splitter, if you set enablesagetvstreamdemux to 0.
But you can't disable the Sage splitter for m2ts. Either try an Arcsoft decoder, or use an external player.

Thanks. This explains why MKV plays ok but not m2ts. I will just convert to MKV.

TMT 5 codec works great with internal sagetv splitter - and has hardware acceleration. Works great for VC-1 and H264.

What video card do you have?

And what VC-1 content are you playing through SageTV?
