Removal of the HTML5 player fixed my problem. But just for curiosity, what plugins/ packages do I need for H.264 support?I will install the proprietary driver then soon (TM) ^^ Best, Heiko
You'll need at least gst-libav and gst-plugins-good for h.264.MSE and "MSE & WebM VP9" can be enabled in about:config (media.mediasource.enabled)
