Intel QuickSync Decoder - HW accelerated FFDShow decoder with video processing

I know that here it will be offtopic, but can you answer my question regarding QS transcoding. What conditions should be met in order to make QS encoder work? I am asking because no matter what I try I can't make it work in MediaCoder, it always returns error 14. Have you ever tried to QS transcoding in MediaCoder on a hybrid setup with fake vga display?

I'm not familiar with MediaCoder.
QS transcoding (HW decoder + encoder) needs an i3 class CPU at a minimum. Fake VGA trick should work.
Which part returns -14, my code? Which function?

BTW, -14 from my code means a bad setup for the decoder or VPP (MFX_ERR_INCOMPATIBLE_VIDEO_PARAM), probably my bug, please specify your setup so I can reproduce.

It's an internal MediaCoder error code, sorry if confused you. My current setup is i7 2600, h67 chipset, 8.15.10.2696 driver from intel's site, Windows 7 x64, fake vga display. Can you please try MediaCoder QS transcoding on your system, I just want to understand what I am doing wrong, or maybe there is something wrong in Mediacoder itself.

Maybe it's a MediaCoder/that OS QS encoder bug.
It doesn't work for me with multimonitor trick either but TMPGEnc and DVDfab do.

MediaCoder works fine when the iGPU is connected to main screen but fails otherwise.
This is a bug in the encoder initialization code. A bug that's very easy to fix BTW.

If someone knows the author I can help fix this in 5 minutes.

Maybe he can be contacted at the MediaCoder forums?

It would be great if you could help with a fix for this bug. I don't know mediacoder' s developer in person, either I don't know his email, but I found some info about him, his name is Stanley Huang, his twitter account, mediacoder bug report forum.

Does anyone have an account in MediaCodec's forum? I already monitor too many forums as it is...

PMd him in the mediacoder forums pointing to post #1385 here.
(he does have an account here on doom9 as well, but hasn't logged in since Jan 2011)

(( wonder if http://forum.mediacoderhq.com/viewto...t=11994#p35686 had been reading this thread or not ))

[aufkrawall]

I got an account there.

O.K., I have registered an account on MediaCoder's forum. I can post a bug report there and send you a reply here, but I don't know what exactly to write.

The initialization problem, which I also had BTW, is solved by initializing the MSDK session using MFX_IMPL_AUTO_ANY. It seems like a documentation or implementation bug.

Change:

sts = m_mfxSession.Init(MFX_IMPL_HARDWARE_ANY, &version);

To:

sts = m_mfxSession.Init(MFX_IMPL_AUTO_ANY, &version);
if (sts == MFX_ERR_NONE) // success
{
    m_mfxSession.QueryIMPL(&m_mfxImpl); // any value other than MFX_IMPL_SOFTWARE means HW accleration
    m_mfxSession.QueryVersion(&m_ApiVersion);
    m_bHwAcceleration = m_mfxImpl != MFX_IMPL_SOFTWARE; // can check if SW is acceptable or not
    sts =  (MFX_IMPL_SOFTWARE != m_mfxImpl) ? MFX_ERR_NONE : MFX_ERR_UNSUPPORTED;
}

return sts;

Note that Virtu might not abstract the driver interface for the encoder (this is not DXVA). If this is the case, the code will fail later on and not in the initialization.

This is assuming that MediaCodec used the sample encoder as is.

Edit
If the MediaCodec author or another user wants to continue this discussion, please open a new thread and send me the link.

I posted a bug report on MediaCoder forum. MediaCoder QS implementation discussion

Please check for MediaCoder's developer reply.

I have two samples which makes problem during playback: http://netload.in/dateiRtEF2R4qzi/In...amples.zip.htm. Framerate indicator shows 2x bigger framerate then real framerate and there's horrible stuttering during playback. I have to disable deinterlacing on QuickSync and use software deinterlacing from FFDShow, then movies play perfectly.

I can't download the file, after waiting forever it says "not found". please post it elsewhere.

The title of the thread "Intel SandyBridge hardware accelerated FFDShow decoder (H264/VC1/MPEG2)" should be changed to Intel SNB & IVB hw ffdshow decoder.

Only to be changed later to: Intel SNB, IVB and HSW hw ffdshow decoder.
I'd change the name but I don't think that's possible...
