Cameron Gutman 2228e4812d Improve debugging for A/V data loss and recovery 2021-06-08 20:01:58 -05:00
Cameron Gutman 5a71a4c092 Use 10ms packets for slow Opus decoders 
With the old 20ms packets, an FEC block was 80ms of audio data.
This is enough data that waiting for the FEC shards can cause
an audio data underflow. The burst of 80ms of audio data after
reassembly fails can then lead clients to drop samples due to
excessive queued data.

Cameron Gutman 8354c403f4 Optimize OpenSSL backend to avoid redundant reinitialization 
It is best to pass as few parameters to EVP_*Init_ex() as possible.
Passing a key, IV, or cipher will cause redundant work to happen behind
the scenes as OpenSSL doesn't check whether they have actually changed.

This avoids a malloc()/free() and redoing AES key expansion for every
message that is encrypted and decrypted.
