[Webos] Fails to play multikey PlayReady stream with singleLicensePer: "content" setting

[TomaszKowalik]

As stated in the title, for some reason WebOS is unable to stream multi-key content. When I remove the singleLicensePer: "content" setting, it plays the PlayReady stream correctly. When I switch to Widevine and keep the singleLicensePer: "content" setting, it also plays correctly. The server is configured to include multiple keys in the license response. Perhaps Im missing something ? Tizen works fine with that setup.
It immediately throws the NO_PLAYABLE_REPRESENTATION error on Webos6, but eg on Webos 4 it fetched the license, started downloading and appending segments, but only black screen without audio was visible

Hi @TomaszKowalik,

It's a known issue, singleLicensePer "content" is poorly handled on WebOS, often only communicating to us the status of the first key (and not all keys), at least with PlayReady.

They (LG) know about the issue and we have a discussion with them about that one (along other issues) but we didn't really see any progress on it for now :/

Thus, the strategy we advised is just to stay in the default "init-data" strategy on WebOS.
Though we wonder if the widevine CDM implementation has the same issue. Did you test with widevine?

[TomaszKowalik]

Yes and it seems that it is working fine with widevine, so the issue remained with PR on the WebOS side
