Hi @Cloud2 - as Chun mentioned, you don’t need explicit permission to access raw data in the meeting SDK anymore
That said, the rc=12 maps to No permission, which could be related to recording permission from the host of the call to record the meeting. You can get recording permission for the call by getting a join token for local recording.
Note that on iOS/Android the raw pipeline uses raw streaming and requires live streaming permission rather than local recording; the concept is the same - no raw frames until the privilege is granted (iOS raw data, Android raw data)
