When I play a x264 clip in the clip monitor (no effects attached), I can see that 2 kdenlive processes are at 100% CPU utilization. When I play a timeline with 3 clips in 3 tracks - I get a speed of 3 fps. When I do 'ffmpeg -hwaccel vaapi -i input.MTS -f null -' to test the load of the decoding on the cpu, I get 9x decoding speed with 1 process producing ~ 40% CPU. Can kdnelive be patched to make use of VAAPI for decoding?
I guess Kdenlive could be patched to use VAAPI but Nvidia GPUs would be left unsupported because of VDPAU support only.

Can you please test the latest version and see if you can still reproduce?
