A query about deprecated "-global_quality" and nvenc. Replace with what ?

Hello. I'm told here https://ffmpeg.zeranoe.com/forum/viewtopic.php?f=42&t=5211&p=12760#p12755 and here https://ffmpeg.zeranoe.com/forum/viewtopic.php?f=7&t=5207&p=12758#p12739 that nvidia in-GPU deinterlacing is currently broken, which is a pity as it would have facilitated GPU decoding/deinterlaci...

Re: NVDEC

thank you very much ! i suppose vf_scale_cuda could be used for gpu resizing if ffmpeg is built with cuda toolkit and it's installed at runtime. i just tried to install the latest cuda 9 toolkit 9.176 on win10x64 with the latest vs2017 updated and the cuda install fails since nvidia's cuda toolkit i...

Re: De-interlace hardware with FFMpeg Cuda/cuvid decoder is not working anymore?

you are right. it is if you want to build/use fancy things like vf_scale_cuda (which seems to be unnecessary if you use -resize in this context). i will be very interested to hear how you go with gpu deinterlacing. https://ffmpeg.zeranoe.com/forum/viewtopic.php?p=12755#p12755 it work but no de-inter...

Re: De-interlace hardware with FFMpeg Cuda/cuvid decoder is not working anymore?

Aren't drivers now around this version ? 388.31-desktop-win10-64bit-international-whql.exe Depending on your build, I noticed this which may or may not be relevant. I am not sure if one should assume that the relevant nvidia CUDA toolkit version 9 needs to be installed in Windows to get the cuda fun...

Re: NVDEC

Thanks ! This commit also changes the Libav code to dynamic loading of the cuda/cuvid libraries. Great ! @DJX would you have an example commandline showing how to use it (assuming one has the latest CUDA installed at runtime, of course) ? https://developer.nvidia.com/cuda-toolkit Hmm, I wonder, does...

Re: VP9 row-mt missing

--row-mt has been ported over to ffmpeg from the vpxenc source. Unfortunately however, this feature is missing. There is an #ifdef conditional called VPX_CTRL_VP9E_SET_ROW_MT in libvpxenc.c that would enable this option during compile time (?) or in some other way I don't understand. It's not even ...
