For [2018]EME Conformance Tests - v20171221 WidevineH264MultiMediaKeySession

I find this test for 8 times Initialize & 8 times GenerateKeyRequest for Key So I can get 8 times provisioning message for key license.

But the Test's success situation is as follows:

In emeTest-20171221164539.js

runner.checkGE(video.currentTime, 15, 'currentTime'); runner.checkEq(testEmeHandler.keySessions.length, 8, 'keySessionCount'); runner.checkEq(testEmeHandler.keyCount, 128, 'keyCount');

Current Time great than 15 sec is pass. Session count is 8 is the same. But Keycount=128, I can't pass it. Only 8 time generateRequest. I can't get 128 keys for 16 keys in one session for this test.

and I find in emeManager-20171221164539.js onKeyStatusesChange() { self.keyCount++; }

So I assume I need to get 128 AddKey() for onKeyStatusesChange() But Now I have no idea to solve it.

I am using Cobalt RC 11.119147. and Widevine CDM 3.2.1

  1. Is this version RC11 is support for multiKeyseeion >
  2. Is there any Sample to process this Test for Widevine CDM process ?
  3. Why need 8 times Init with 8 times GenerateRequest ? why not one init and 8 times GenerateRequest ? does Init need to clean Something ? or We need 8 CDM instance ? Each one have only one session ?

  • Is any one can help to explain OnSessionKeyStatusesChangedFunc( SbDrmSystem wrapped_drm_system, void* context, const void* session_id, int session_id_size, int number_of_keys, const SbDrmKeyId* key_ids, const SbDrmKeyStatus* key_statuses); What is int number_of_keys, const SbDrmKeyId* key_ids, const SbDrmKeyStatus* key_statuses ????? How to call back with these three param. – Jackie Sun Jan 22 '18 at 12:54

We recently fixed a bug in the test, is it possible for you to try again to see if you can still reproduce the above mentioned issue.

  • Could you explain for OnSessionKeyStatusesChangedFunc( SbDrmSystem wrapped_drm_system, void* context, const void* session_id, int session_id_size, int number_of_keys, const SbDrmKeyId* key_ids, const SbDrmKeyStatus* key_statuses); What is int number_of_keys, const SbDrmKeyId* key_ids, const SbDrmKeyStatus* key_statuses ????? How to call back with these three param. – Jackie Sun Jan 22 '18 at 12:56
  • There can be multiple keys in one session. |number_of_keys| is the number of the keys in the session, it also indicates how many elements are in the next two arrays. |keys_ids| and |key_statuses| contain the key ids and statuses of these keys respectively. – xiaoming Jan 23 '18 at 02:20
  • Ｄo you have any smaple code to call OnSessionKeyStatusesChangedFunc() with those parameter ? – Jackie Sun Jan 23 '18 at 06:12
  • I find how to implement those parameter. thanks for your answer – Jackie Sun Jan 23 '18 at 13:09
