Membrane RTP plugin v0.21.0

View Source Membrane.SRTP.Decryptor (Membrane RTP plugin v0.21.0)

Converts SRTP packets to plain RTP.

Decryptor expects that buffers passed to handle_process/4 have already parsed headers in the metadata field as they contain information about header length. The header length is needed to avoid parsing the header twice in case of any elements preceding the decryptor needed the information to e.g. drop the packet before reaching the decryptor. ExLibSRTP expects a valid SRTP packet containing the header, after decryption, the payload binary again includes the header. The header's length simply allows stripping the header without any additional parsing.

Requires adding srtp dependency to work.
