H264 Stream Decode

Hi,
We use Intel Media Samples 5.0.491.98719 sample_decode to rewrite program.
12 stream decoding performed simultaneously.
We encountered some problems,consult your
1. Hardware decoding can be performed at the same time a lot it?
2. NV12 to RGB can use VPP? (we use ffmpeg now, but effectiveness not good)
We Project only build on vs2008.

Hi Joe, 

Thanks for sharing the information. Can you please provide more details to "Hardware decoding can be performed at the same time a lot it?", I don't believe we got it right. 
Regarding " NV12 to RGB can use VPP? (we use ffmpeg now, but effectiveness not good)"
Yes you can use VPP to do color conversion from NV12 to RGB32, you can check what all MSDK support in our manual -

Glad you got the first query resolved. nMaxFPS in the sample_decode is the limited fps for rendering the decoded output which can be passed as input argument -f option when rendering the o/p with fps given as an input argument by user. 

Let us know if you have any more questions. 

Thanks,
Surbhi
