codec id with HEVC: Chromecast Ultra doesn't like it

We are doing some tests with HEVC encoded videos (generated by Elemental live) and pushing those into USP.
This works with several devices, but the new Chromecast Ultra doesn't like playing the result.

"The type provided ('video/mp2t; codecs="mp4a.40.2,hev1.1.6.L153.BB0"') is unsupported"

Some googling revealed that .BB0 is at least uncommon, while hev1.1.6.L153.B0 exists.

I don't have the spec and can't prove it, but I think that .BB0 is wrong and should read .B0

If I change the string to hev1.1.6.L153.B0 , chromecast ultra indead plays it.

"CodecPrivateData" value="010160000000B0000000000099F000FCFDF8F800000F03200001002140010C01FFFF016000000300B000000300000300991140C000000300400000067A210001003C420101016000000300B00000030000030099A001E020021C59445924C96B016A020203CA00000300020000030033E02DEE7A800017D7840002625A2022000100084401C0ACBC25FB24"

I can provide test data if needed.

Hi,

Thanks for the report, we'll look into it.

Could you post this to support [at] unified-streaming [dot] com as well? If possible with a test file.

Kind regards
