1271883 - [EME] Widevine fails on Shaka player demo with DRM.REQUESTED_KEY_SYSTEMS_UNAVAILABLE

Status: RESOLVED FIXED

(Core :: Audio/Video: Playback, defect, P1)

Shaka player demo is failing on Widevine content with error DRM.REQUESTED_KEY_SYSTEMS_UNAVAILABLE.

This is a regression from bug 1271242, which thankfully hasn't been uplifted - and doesn't need to be.

The problem is that I made EMEDecoderModule::SupportsMimeType() call GMPDecoderModule::SupportsMimeType() specifying a GMP to use, but I didn't add the widevine keysystem to the take of keysystems that we recognise in GMPDecoderModule. So we're unable to create an EME MediaDataDecoder.

I broke Widevine in 1271242 when I changed EMEDecoderModule::SupportsMimeType()
to call GMPDecoderModule::SupportsMimeType() specifying a GMP to use, as I
didn't add the widevine keysystem to the take of keysystems that we recognise
in GMPDecoderModule. So we're unable to create an EME MediaDataDecoder.

In order to make Widevine EME work again, we need the Widevine keysystem string
in sGMPCodecs in GMPDecoderModule.cpp.
