Maybe i can help.
I have looked at your link and the real URL to the video (ending with .mp4) ist this:
[video src="https://www7.mp4upload.com:282/d/scxwalc3z3b4quuotwuqqzswknohygn357wjaienbxvlyrp53by6wfrv/video.mp4" /]
but idk if they use a hash to change the link….
I am so Sorry. My own Cache tricked me…. somehow when i change the URL the videos wont change. But this time the wrong URL was in there but it showed me a Video in the old Plugin.
Sorry for interrupting. everythings working fine now.
The video URL was saved and also the player was embeded (did it for version 1.1.0 not) but when i press play the player says “Error loading media: File could not be played” but in version 1.0.2 it did.
Edit: I downgraded to version 1.0.2.
It wont play MP4 after the 1.1.1 update in the Premium version.
