DXVA2 \"copy back\" :
In our series of hardware decoders, the new DXVA2 decoder now features hardware decoding also for AMD/ATI.
Its a \"copy back\" (or \"renderless\") decoder - that means all frames are copied back from the GPU to normal memory.
Sadly, however, AMD/ATI cards suffer from a serious performance penalty, which prevents them from showing their full potential. The decoder is fully Blu-ray compliant, and even goes beyond that, however playing 60fps movies will most likely not work fluidly.
H.264, VC-1 and MPEG-2 are fully supported (progressive and interlaced), as long as your hardware can keep up. Very old AMD/ATI cards, like 3000 series and below, might not be able to use this decoder. 4000 and up seem to be working ok.
I do have plans to work on a \"native\" DXVA2 decoder, which does not need to copy the frames back from the GPU, avoiding this performance bottleneck - however that goes with the loss of the flexibility of course. No post-processor, only EVR, etc.
For everyone else, i recommend to stick to your native decoders (CUVID/QuickSync), as they generally work better and faster then DXVA2.
Known Issues:
-Interlaced H.264 on Intel can show image corruption
-Some MPEG-2 streams show image corruption (all GPUs)
There is also the potential for crashing the GPU driver. It happened mostly on VC-1 interlaced, and all cases i encountered i also fixed, but if it happens, just let me know, and i\'ll look into it.
MPEG-4 ASP in the CUVID decoder:
There seems to be an issue in the latest NVIDIA drivers that cause the decoder to not work on most MPEG-4 ASP files!
Older drivers, like 270 series, seem to be working OK.
Its experimental, use it at your own risk, its off by default.
And the rest... :
Everything else is pretty much standard changes, a few new video formats supported, a number of improvements inherited from ffmpeg, the usual number of bugs fixed.
I still didn\'t get around to re-writing the installer, but i hope i can get the motivation to do it for the next big release.
What else is up next? I haven\'t decided. There is some features on the table, audio mixing, dvd support, some subtitle work .. we\'ll see.
