Unsupported NAL Type 6 debug messages

[travishaagen]

When debug messages are enabled in rtspv2.RTSPClientOptions, I see many messages of the form:

2021/04/17 07:10:12 [Unsupported NAL Type 6]

These appear to be Supplemental Enhancement Information (SEI) NAL types for H.264.

Would it be beneficial to simply note in the code that these are not currently supported, instead of logging these messages for NAL Type 6 specifically? Other unsupported NAL types would continue to be logged.

@deepch Seems like it hasn't been fixed yet.
The same messages when playing an RTSP(h264) stream using MSE.

In case this debug message I do not see the stream at all, mse output [Unsupported NAL Type 6].
