Hello all,
I’m wondering about the expected state of GPU decoding in Kdenlive. What should I actually expect on an Intel platform (Skylake) which has verified working GPU-accelerated decode/encode on common H264 and H265 8-bit profiles outside of Kdenlive ?
The documentation seems to hint that GPU encoding is supported for a subset of formats. I cannot, however, seem to find a way to enable GPU decoding.
Practically, when transcoding a video clip for use inside a project, the encoding does seem to happen on the hardware (the command-line sets the output codec to -c:v h264_vaapi and intel_gpu_top shows GPU video usage) but the decoding takes all available CPU cores and does not seem to happen on the GPU. On the same video, mpv uses GPU decoding (working with either VAAPI or Vulkan) so it should be correctly supported.
Thanks for the help!
