[HELP] Filtering -> Speed Change -> Change Speed doesn't seems to work (Hybrid 2024.01.12.1)

[Selur]

'Change speed' should just change the flags of the container (and if possible stream) since neither Avisynth nor Vapoursynth are used it's no surprise that switching between them does not change anything.

the problem is with the decoder call:

ffmpeg -y -loglevel fatal -noautorotate -nostdin -hwaccel auto -threads 1 -i "1.mkv" -map 0:0 -an -sn -vf scale=1280:720,fps=25/1,scale=in_range=tv:out_range=tv -pix_fmt yuv420p -vsync 0  -sws_flags spline -f rawvideo -

then fps=25/1 part is wrong, this should be "fps=24000/1001".
=> Looking into it.
