I fix this exception, after build result here - AppVeyor
Thank you!
One more thing, I think it's not an issue in MPExtended or WebMediaportal, probably in video.js (or its flv js). The videos in the browser are laggy. Frames not missing, but looks like it's low fps or something like that (maybe I will create a video of it). No matter if it's live channel or TV Recording. And streaming stops if I try to rewind or fast forward (in TV recording, didn't try timeshift in live channels). On Android with ffmpeg everything looks ok with MPTvScheduler.
This happens with "Flash" player presets, with direct I got the following message in every browser: " The media could not be loaded, either because the server or network failed or because the format is not supported."
I've tried in Vivaldi, FF and the new Chromium based Edge, the result is the same. Does this happen at anyone else? Is there any solution?
