Apparently, NVIDIA GeForce Game Ready 378.66 WHQL which released on 2017.2.14 mentions new features of upcoming sdk 8.0
The changelog:
Video SDK 8.0
•High-bit-depth (10/12-bit) decoding (VP9/HEVC)
•OpenGL input surface support for encoder
•Weighted Prediction
•H.264 ME-only mode enhancements
So, when will the updated SDK8.0 come out?
I have few questions on the upcoming “Weighted Prediction”.
Is this feature applicable to P or B frames or both?
Does this feature exclusive to H264 only?
I know…just kinda disappointed.
Weighted Prediction only usable if B-frame is disabled for H264. At least this is useful for HEVC since nvenc HEVC encoding doesn’t support B-frame in first place. Until I read Weighted Prediction is an exclusive feature for Pascal series.
T-AQ still not available for HEVC, but Spatial aq-strength slider ought to work for HEVC encoding in SDK 8.0. Question:
In nvEncodeAPI.h, uint32_t aqStrength :4; , but Using_FFmpeg_with_NVIDIA_GPU_Hardware_Acceleration.pdf recommends it to be set at -aq-strength 8 So, which recommendation to follow? 4 or 8?
8.0 changelog also mentioned Improved quality for HEVC spatial adaptive quantization. What exactly being changed here?
