Win10Edge HEVC multiperiod test gives "error: creating source buffer of type: audio"

[Murmur]

Weird errors on Win10Edge-H265 multiperiod, no DRM so to make test easier. Player displays error creating source buffer dialog on Edge-H265, clicking on OK continues playback until few more times playback stops. Similar H264 test works fine. You anyone can replicate an error or just my laptop?

Installed HEVC Video Extension so Edge+Chrome+Firefox playback works. https://apps.microsoft.com/detail/hevc-video-extensions/9NMZLZ57R3T7?gl=&hl=

>> Daniel: So there is no changeType support when using HEVC? Its weird that the issue also occurs on the audio SourceBuffer. Can you please create an issue on the dash.js Github for this. Did you also check if it works in Shaka? _>> ShakaPlayer playback runs much longer and no error in a console log_

Firefox ver120+ beta and HEVC (needs the same extension as Edge+Chrome). about:config | media.wmf.hevc.enabled=1 | restart Firefox WinStore HEVC Video Extension

HEVC playback works on h264-multiperiod and h265hbr-multiperiod tests, so it seems only Edge browser has problems with this test case.

Confirmed, MSEdge works with the current Dashjs_V5 demo player, see h265hbr dash url in a first post. https://reference.dashif.org/dash.js/nightly/samples/dash-if-reference-player/index.html
