No clearkey pssh in 2015's ClearKeyVideo test #31

Closed moorthy-bs closed 6 years ago

moorthy-bs commented 6 years ago

I observed that only playready pssh of length 848 and widevine pssh of length 193 are with 2015 ClearKeyVideo test's video, however, 'drm-preferred-decryption-system-id' is set to ClearKey UUID. Though preferred ID is clearkey but the browser's EME is picking widevine due to there is no respective pssh. Same I observed also in 2016's ClearKeyAudio

Here is the log for reference

Since this is clearkey test and the stream should have Clearkey's pssh box but only playready and widevine pssh boxes are found. Noted that there is no pssh box for clearkey, is there any specific reason for this or a bug?
