Typescript typing file does not contain "SupplementalProperty" in the "dashjs.MediaInfo"

[Darkwinde]

Hi everybody,

in our MPD we defined an audio adaption set for Dolby Atmos. The identification is been done by the SupplementalProperty value "JOC" of the audio adaption set. Compared to Exo Player, Dash.JS does not provide a sample mime type, like "audio/eac3-joc", for identification therefor we need to stick to certain properties.

The issue is, that the typing file "index.d.ts" does not contain a definition for "SupplementalProperty" and therefor these information are not accessable within our Typescript project.

I like to request "SupplementalProperty" to be typed and made available to dashjs.MediaInfo.

supplementalProperties is an object with the keys being the schemeIdUri of the SupplementalProperty and the values being the value of the SupplementalProperty. For instance:

{
"tag:dolby.com,2018:dash:EC3_ExtensionType:2018": "JOC",
"tag:dolby.com,2018:dash:EC3_ExtensionComplexityIndex:2018": "16"
}

for

<SupplementalProperty schemeIdUri="tag:dolby.com,2018:dash:EC3_ExtensionType:2018" value="JOC"/>
<SupplementalProperty schemeIdUri="tag:dolby.com,2018:dash:EC3_ExtensionComplexityIndex:2018" value="16"/>

I have added supplementalProperties to the Typescript definition file with type object in #4080 . Does this solve your problem?

Hi @dsilhavy,
I need to check this in the release version, but looks fine for me so far.
