Just found some opensource stuff to access VCE (AMD) in virtualdub (yes I still use it :P ) and a versatile screen capture util with VCE support. Gotta admit I never used AMD's utils built in the drivers (AMD Quickstream? Raptr? Gaming evolved? I dunno they just keep tossing out stuff with "user friendly" GUI's that won't get you anywhere) as they seem to be more game oriented.

OpenencodeVFW (based on AMD's openencode source):

Open Broadcaster with VCE support:
https://obsproject.com/forum/threads...support.13996/

I only have VCE 1.0 equipment, so couldn't try out VCE 2.0 (kaveri, hawaii and low power am1 beema/mullins) which supports B-frames and up to 5.1 profile
It's fast (transcoding x264 720p at around 80 fps- perhaps bottlenecked by the decoder?), even on highest quality settings. But the bitrate/quality ratio isn't as good as x264.

My wishlist for VCE:
Higher quality even at the cost of speed decreases.
Dual graphics/X-fire support (use more than one dGPU and/or APU to encode/assist encoding the same stream).
hybrid GPU/x86 encoding: "software encoding" with more parts of h264 on the GPU, like OpenCL lookahead - maybe with HSA and the new H265 standard built around multi-core this will be easier to implement.
