In the “add video” window of the player, when adding an encrypted HLS video, the decryption of the encryption key is broken. This happens in the Safari browser on Mac. In Chrome browser no problem, one clicks “decrypt” and the decrypted key appears in the area above. In Safari however this doesn’t happen properly. The indicator says “video ok” but it doesn’t play and throws error messages about video not encoded properly etc.
I just wasted a lot of time on this before finding out it is actually due to the browser, so I thought I’d mention it here.
