qtdemux selected the first system corresponding to a working GStreamer decryptor. With this change, before selecting that decryptor, qtdemux will check if it has context (a preferred decryptor id) and if not, it will request it. The request includes track-id, available key system ids for the available decryptors and even the events so that the init data is accessible. [eocanha@igalia.com: select the preferred protection system even if not available] Test "4. ClearKeyVideo" in YouTube leanback EME conformance tests 2016 for H.264[1] uses a media file[2] with cenc encryption which embeds 'pssh' boxes with the init data for the Playready and Widevine encryption systems, but not for the ClearKey encryption system (as defined by the EMEv0.1b spec[3] and with the encryption system id defined in [4]). Instead, the ClearKey encryption system is manually selected by the web page code (even if not originally detected by qtdemux) and the proper decryption key is dispatched to the decryptor, which can then decrypt the video successfully.
