Streams media error on Edge about rx-player HOT 4 OPEN

Hello,

OK :/, we're used to issues with PlayReady on Edge windows sadly, and MEDIA_ERR_SRC_NOT_SUPPORTED , along with sometimes the even more cryptic MEDIA_ERR_UNKNOWN (which is when the error code is not documented in the HTML standard) are generally indicative of lower-level bugs and are hard to debug.

When that issue appears, are you relying PlayReady SL3000 or SL2000? Is there multiple keys depending on content quality? We could try locking a specific video & audio quality and see if the problem still occurs, though if I understand correctly, you're not able to reproduce it on your side.

We've also seen a raise of Playready-related issues lately at Canal+, which coincides with a new influx of differently-packaged contents, so we do not know if that issue is linked to a change at the packaging-level, CDM-level, or both.

Most of the time we try to understand the issue and report it to Microsoft, but this does not always go in a direction that suits us. Debugging sessions are very difficult to perform (we do not control to the lower-level code, let alone the CDM logic, so we're forced to make a lot of assumptions), time consuming and most times end up with an unsatisfactory solution. We've for example at one point reported a confirmed PlayReady issue preventing us to play some contents, but due to priorities on Microsoft's side, they advised us not to await a fix but to perform complex and user-visible work-arounds such as always starting playback playing qualities with the lowest security requirements.

Because of this, we're currently testing a way to detect when those types of issues occur, to fallback either on PlayReady SL2000 or Widevine, as a last resort where no work-around is found.
For now, this would happen through another loadVideo call (though we're currently drafting the improvement of the reload method, to allow the communication of more options such as a different key system) but long term we're also exploring the possibility of doing it inside the RxPlayer.

@peaBerberian I will provide some feedback about the different set-ups which are used for our content. There is also multi-key DRM in certain cases. I would need to review if there are specific cases which are failing. I would need to discuss with the team managing the content on details.

We target to use DASH+PlayReady to avoid "leaks" with common Widevine leaks.

We target to use DASH+PlayReady to avoid "leaks" with common Widevine leaks.

Instead of giving up about all Widevine clients, you could also limit distribution of content keys for higher quality video tracks to Widevine devices that are "more trusted" than the default Widevine L3 implementation on low end Android devices (e.g. limit distribution of HD keys to L1 devices or even to only those L1 devices that belong to a carefully chosen whitelist).

@peaBerberian in the reported error case the affected stream was a single key SL2000 stream. We have different variants available and for some prime content multi-key DRM is used. Right now the issue is reported mostly internally as Edge is not used that much, but there has been discussion (within C+ and M7) on using DASH/Playready on Edge browser and promoting this browser for (U)HD content.

If we could detect such issues; we could consider some fall-back.
