Computing Latency Introduced by Media Transcoding Operations

摘要

Systems and methods for computing latency introduced by media transcoding operations are described. In some embodiments, a method may include receiving incoming Real-Time Protocol (RTP) packets, each having time of arrival and a payload encoded with a first codec and receiving outgoing RTP packets, each having a time of transmission and a payload encoded with a second codec. The method may also include calculating a latency associated with a transcoding of at least one of the incoming RTP packets into at least one corresponding one of the outgoing RTP packets based upon a difference between the time of transmission of the at least one corresponding one of the outgoing RTP packets and the time of arrival of the at least one of the incoming RTP packets. In some cases, the incoming and outgoing RTP packets may be Voice-over-Internet Protocol (VoIP) packets.

主权项

1. A method, comprising:
receiving an incoming Real-Time Protocol (RTP) packet including information encoded with a first codec; decoding the information using the first codec; encoding the decoded information using a second codec, the second codec different from the first codec; creating an outgoing RTP packet including the information encoded with the second codec; and computing a latency associated with decoding and encoding operations.
