tvOS: MPEG-TS with UHD stream choppy and unstable
My App uses TVVLCKit to play back TV streams forwarded from Enigma 2based DVB-Receivers (DVB-S and DVB-C). As now 4k Video comes along via DVB-S and DVB-C I received first reports about issues during playback. Obviously both are using an AppleTV 4k.

One user reported, that playback of the Astra UHD Demo stream is choppy. He showed me a video of his setup playing this stream, and it is choppy. He prepared a small recording of the stream I can share with you. I also tried to playback the stream with VLC on macOS and well... consumed lots of CPU and was also choppy. As it is Astra UHD demo I assume he uses DVB-S. First thought was low network performance, but this should be fine.

Another user reported, that playback works fine - not choppy - for quite a while. But then after a while (sometimes 10 minutes, sometimes 30 minutes) the playback stops video, audio continues. He has to stop playback and restart the stream again, then playback is fine for another period of time. He uses DVB-C and unfortunately he is not able to prepare a recoding of the stream for me.
Looks like 4k playback is challenging...
