System cannot find the file specified(mpv.net + uosc)

[DonBureq]

Hello I have a problem with thumbfast script on Mpv.net(windows) using uosc OSC. The thumbnails are not showing at all and the console is showing "System cannot find the file specified" errors every time i hover cursor over the seek bar. I've checked the regular mpv and both scripts works without problems. I have also tried to run mpv.net with default settings but it didn't help much. Thanks

This is because the script only works for mpv, which needs on using mpv commands in subprocesses. https://github.com/po5/thumbfast/blob/eb21b2e871144a328f93c4597cc1932b43783e6a/thumbfast.lua#L253-L255

Unfortunately, mpv.net is based on libmpv(mpv-2.dll), so it cannot use the mpv commands in subprocesses. If you really want to use this script with mpvnet, you have to add mpv to PATH first.

Relevant: https://github.com/mpvnet-player/mpv.net/issues/262, https://github.com/marzzzello/mpv_thumbnail_script/issues/2

HI. Thanks for your help. I can confirm that adding mpv to PATH variable fixed the problem. Closing

wtf, is running two different player efficient?

If you're asking in the context of mpv.net+regular mpv, it's not any less efficient than the script's normal operation.

If it's the normal operation of running a background instance to generate thumbnails you're asking about, it's a minor memory usage increase over not having the bg instance, with the benefit that generating a new thumbnail is fast (and cheap thanks to your OS's disk access cache).
It's better than the alternative of heavy pre-generating of every thumbnail, and lets us have frame-accurate thumbnails for where you'll end up after seeking.

thanks, this is what i wanted to know. i even enabled luajit so i guess it will be more efficent
