AUD, SPS, PPS missing from Media SDK bit stream.

Rosen__Daniel · ‎07-27-2014

On my I3770 system, the AUD, SPS, and PPS are missing from the output bit stream. The buffer appears to be padded with leading zeros. On an older Core I5 with HD 3000, the output stream stream is correct. Using the Media SDK R2 2014 with Intel video drivers, 10.18.10.3621 with hardware encode. I can duplicate with the standard sample_encode applications.

Both systems are running Windows 8.1 x64 although the applications are 32 bit. Using VS2010.

Tried switching from the hardware encoder to a software encoder (on the I3770), and the m_mfxSession.Init dies in the debugger.

Any suggestions on how to track these issues?

Thanks for your report. A few more details about the two different machines could help. Could you make sure I've interpreted correctly and fill in the blanks below?

New machine (AUD, SPS, PPS missing)

Processor: i3770
Driver version: 10.18.10.3621
Media SDK Version: Media SDK R2 2014

Old machine (works)

Processor: ?
Driver Version: ?
Media SDK Version: ?

Any chance you could include more details on how to replicate with sample_encode? If you've modified anything, please send the lines changed (or attach the full source if that is easier).

Regards, Jeff

I may have found the problem. According to the debugger the mfxSession.Init, loaded the library from here:

loaded 'C:\Program Files\Intel\Media SDK\libmfxhw32.dll',

However, there's also a copy of the same dll in the 2014 client R2 folder with a slightly older date. After renaming the Intel\Media SDK folder to something else, our software loads the library from:

Loaded 'C:\Program Files\Intel\Media SDK 2014 R2 for Clients\bin\win32\libmfxsw32.dll'

And now I get the AUD, SPS, PPS. However the QuickSync is defaulting to a software implementation instead of hardware.

THe is the contents of 2014 R2 bin folders:

OK, the problem was never really fixed. Turns out when I deleted the "c:\program files\intel\media sdk" folder, it default to the software driver. I've since deinstalled and re-installed both the intel video driver and the media sdk 2014 R2, and now I'm back to getting encoding output without AUD, SPS, and PPS with an unmodified version of sample_encode.

What's next? Below is the output from the Intel Media SDK:

Hi,

The 'C:\Program Files\Intel\Media SDK\libmfxhw32.dll' was the proper library to hardware to load and was installed as part of your Intel HD 4000 graphics drivers.

The issue you describe with AUD,SPS,PPS is something that could occur if the platform BIOS is not fully supporting your CPU. Could you please run "DXDIAG" on your platform, select "Save All Information", and provide us the report?

Do you know if the motherboard and BIOS you are using was provided at the same time that the Intel(R) Core(TM) i7-3770 was placed in system, or was this platforms CPU upgraded from a 2nd Generation CPU?

Any information about your platforms BIOS provider would be useful. THANKS

Hi Tony, thanks for the quick response.
