  vulkan: drop bgr_workaround - Lynne git.videolan.org Git - ffmpeg.git/rss log
  vulkan: drop bgr_workaround Vulkan's main issue around using BGR is simple. The letters in the shader don't match up (rgba in shader, bgra in format). So of course, rather than allowing "bgra" or other permutations of formats in the shader, they went the nuclear option and spent months writing an extension to get rid of the need to have a format in the shader to begin with. All this to solve a problem that should never have existed to begin with. This fixes BGRA images since enabling WithoutFormat, as the GPU now remaps without your involvement. [DH] (...)

  How to convert an ffmpeg texture to Open GL texture without copying to CPU memory - PPP Newest 'ffmpeg' Questions - Stack Overflow
  This ffmpeg example demonstrates how to do hardware decoding: https://github.com/FFmpeg/FFmpeg/blob/release/4.2/doc/examples/hw_decode.c At line 109 it does this: /* retrieve data from GPU to CPU */ if ((ret = av_hwframe_transfer_data(sw_frame, frame, 0)) < 0) I want to avoid this because it takes time. Therefore, I need a way to reuse that decoded video, which is in GPU memory, to redo color conversion.
