Getting Macroblock information from QuickSync H.264 decoder

Getting Macroblock information from QuickSync H.264 decoder

Hi,

I would like to know if there is a way by which we can get MBInfo (Macroblock Information) from H.264 decoder on QuickSync

We are using > HD4600 versions with Windows 8.1. Does OpenCL or IntelMediaSDK support this export of information like motion vectors, MV bits, Texture bits, Coded block pattern, etc

Regards

Hi Murali,

I agree with you that more info from decode would be very good to have, but this isn't as easy to add as it may seem.  Media SDK can only provide data accessible from the driver, and the driver can only interact with interfaces available in hardware.  For now, would it be possible to consider a slower software-based "diagnostic mode" with this data, and a faster hardware accelerated mode without?

Regards, Jeff

Hi Jeffery,

Many thanks for the response. We will check it out on the diagnostic mode and get back to you. Is this something that is part of Intel MediaSDK?
