Re: new changes in ffmpeg - OpenCL hwcontext implementation

OK, for closure, it turns out :- (a) building ... eg does cross-compiling still need an OpenCL library eg as built from KHRONOS Yes. No change to process. (b) what changes to a commandline are required to run it (with the new filter) as a result of this new "hwcontext" thing The old OpenCL approach ...

Hmm. There are a bunch of OpenCL updates recently a la https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/b25d8ef0a7a880443fb713603d7f4259e30b84dd lavu: OpenCL hwcontext implementation and https://git.ffmpeg.org/gitweb/ffmpeg.git/commit/3650cb2dfa644ff4260d226b783747ff9e020ad1 lavu,lavfi,ffmpeg: Remove...

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

Would this be approximately the right direction ? "%ffmpegexex64%" -nostats -i "%~1" -map_metadata -1 -sws_flags lanczos+accurate_rnd+full_chroma_int+full_chroma_inp -c:a copy -filter:v yadif=0:0:0,unsharp=opencl=1:luma_msize_x=3:luma_msize_y=3:luma_amount=0.5:chroma_msize_x=3:chroma_msize_y=3:chrom...

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...
