What withelds Media Foundation from playing HLS streams above 1080p? RRS feed

  • Question

  • The HLS file I'm using supports resolutions from 360p, 480p, 720p, 1080p, 1440p and 4K but Media Foundation starts with one fragment of 360p and then only plays 1080p, it does not play 4K even though all 16, 1080p fragments are being downloaded within a second. I expected Media Foundation to choose the 4K video fragments because of the internet speed but apparently it doesn't. When I supply a .m3u8 playlist with only a 4K video it simply plays it like it should. What other factors take part in making Media Foundation decide which video quality to play? And how would I allow a higher quality video if clearly it should have no problem playing it?
