Topic: SVP not correctly picking up base FPS

After some research I have concluded that this issue predominately occurs with the latest versions of mpv, vapoursynth, vapoursynth-extra-plugins and libass5 from the djcj repo. I have been able to replicate with older versions too, even though it was far less prevalent there. Meaning, that SVP is definitely involved.

Not exactly sure what the problem is, even after consulting wmf at github, so I hope you might find an answer.
Using Lubuntu 14.04 and the latest version of SVP4Linux.

Instead of the output framerate being at an expected 59.9FPS it is sometimes lower or higher.l, while repeatedly playing the same file.

Here some log outputs of the same Youtube Video being played  multiple times in a row.

"22:06:09.876  Playback [2e751307]: enabled while video is playing
22:06:09.896  Playback [2e751307]: playing at 59.9505 [59.9505 *1/1]

22:06:23.359  Playback [2e751307]: enabled while video is playing
22:06:23.375 Playback [2e751307]: playing at 52.7546 [52.7546 *1/1]

"22:07:09.876  Playback [2e751307]: enabled while video is playing
22:07:09.896  Playback [2e751307]: playing at 89.9205 [89.9205 *1/1]

"22:08:05.636  Playback [2e751307]: enabled while video is playing
22:08:05.656  Playback [2e751307]: playing at 74.3105 [74.3105 *1/1]

Any ideas?

At first I thought it might be composite, as I use KDE with vsync, but it still occurred after turning it off.

It must either be mpv, SVP or both.

Re: SVP not correctly picking up base FPS

yep, we already know that from another report about issues with Plex Media Player

every 2nd (!) video started w/o closing mpv window gives incorrect source framerate reported by mpv

===
upd: found the reason, will be fixed asap

Re: SVP not correctly picking up base FPS

Could you explain the reason to me?

I create installable custom distro ISOs for clients and if it was possible to just manually edit with chroot and roll back some packages in order to fix the problem, instead of starting from scratch, it would be awesome.
