[Cin] cingg faster than ffmpeg itself on pulling frames!?

[Andrea paz]

I did two tests with ffmpeg standalone:

1)
time -p ffmpeg -hwaccel vaapi -i hdr_02.mp4 -c:a copy -c:v rawvideo -f
nut /dev/null

fps=26
speed=0.438x
CPU load=5%

2) (no vaapi)
time -p ffmpeg -i hdr_02.mp4 -c:a copy -c:v rawvideo -f nut /dev/null

fps=100
speed=1.66x


I loaded the video to CinGG.
Playback:

Vaapi
X11 --> ~59.7 fps (some freeze at 49 fps)
X11 reverse playback --> 9-18 fps (many artefacts)

OpenGL --> ~12 fps (many freezes and artefacts)
OpenGL reverse --> 7-9 fps (inusable for freeze and artifacts)

No vaapi
X11 --> 59.7 fps (no artefacts)
X11 reverse --> 3-9 fps (many freezes and artefacts)


Rendering (h265.mp4 and hevc_vaapi_8b420.mp4):

h265.mp4 --> 10 fps
hevc_vaapi_8b420.mp4 --> 23.7 fps
