Query number hw decoding instances

Question asked by sheigl on Jun 26, 2014

We are using DXVA2 via ID3D11VideoDevice API to support hw-accelerated decoding of h.264 video.

What is the perferred way to determine if the hw decoders are overloaded / out of instances.

Currently we measure the decoding time and if it's above a threshold (i.e. GPU/UI grinding to a halt) we drop the decoding session or fall back to i-frame only mode.

Is there any better method to find decoder overload in advance? i.e. query number of hw decoders, max. supported bandwidth etc?


Thank you very much!
