I'm decoding a h264 video stream into rgb4 (BGRA32) using media sdk 2016.
When I use the software acceleration the alpha channel is always set to 0, instead using hardware acceleration the alpha channel is set to 255.
What OS and hardware are you using? If Windows, what driver # is installed? I've replicated in Windows on BDW but want to be sure this is what you're looking at.
