Hi Gilles,

thanks for the hint! I changed the @codecs attribute to hvc1.1.6.L93.90,
but still get the same error: “NotSupportedError: Failed to execute
'addSourceBuffer' on 'MediaSource': The type provided ('video/mp4;
codecs=hvc1.1.6.L93.90') is unsupported.”

Any thoughts?

Thx & best regards,

I don’t know if that’s the cause of the error, but the @codecs attribute of
this MPD is not correct (hvc1.1.c.L93.90 should be hvc1.1.6.L93.90, the
error has been reported to the authors of this test sequence, and I think
they have fixed it now).

Dear all,

I don't know if this is the proper list for that: (if not please advise me
which would be a better place to raise this question, already tried it on

I want to use HEVC content on Chrome for Android on a Nexus 5 phone using

·         Playing plain HEVC mp4 files in Chrome/Android/Nexus5 works fine,
e.g. this one: http://www.bitmovin.net/hevc/720p.mp4

·         But playing an HEVC DASH stream doesn't work, as the MSE doesn't
support the content type: "NotSupportedError: Failed to execute
'addSourceBuffer' on 'MediaSource': The type provided ('video/mp4;
codecs=hvc1.1.c.L93.90') is unsupported.". I'm using this stream:

Is the error caused by a wrong codec attribute or is the HTML5 MSE on
Chrome for Android just not (yet) supporting HEVC on HEVC-enabled Android

Thanks and best regards,
