Issue of RtcpNackResponder nack data

[hqs1]

Hello, I am using libchannel and the nack data seems to be inconsistent with the media source data. The data sent by the same sequenceNumber and nack seems to use the same message_ptr. It seems that the data sent by nack has secondary encryption.

The storage media data here appears to be weakly referenced

libdatachannel/src/rtcpnackresponder.cpp

Line 61 in b7f1f03

mStorage->store(message);

thank you !

Ow, indeed, this is due to SRTP encryption happening in-place so messages referenced by RtcpNackResponder end up corrupted. I'm pushing a fix.

Thank you for reporting, it should be fixed by #1118

Ok, thanks. I'll test it and give feedback.

After testing, it can be retransmitted normally.
