RTP Payload Types (PT) for standard audio and video encodings - Closed
Registration Procedure(s)
- Registry closed; see RFC 3551, Section 3
Reference
- RFC 3551: RTP Profile for Audio and Video Conferences with Minimal Control
Note
The RFC "RTP Profile for Audio and Video Conferences with Minimal Control" RFC 3551 specifies an initial set "payload types". This list maintains and extends that list.

RTP Payload Format Media Types
Registration Procedure(s)
- Registry closed
Reference
- RFC 4855: Media Type Registration of RTP Payload Formats
- RFC 9751: Closing the RTP Payload Format Media Types Registry
Note
In addition to the RTP payload formats (encodings) listed in the RTP Payload Types table, there are additional payload formats that do not have static RTP payload types assigned but instead use dynamic payload type number assignment. Each payload format is named by a registered media subtype as listed in the following table. As new payload formats are specified, their registered media subtypes should be added to this table. In addition, for the payload formats listed in the RTP Payload Types table above, the "encoding name" is also registered as a media subtype under the media type "audio" or "video". The clock rate and number of channels shown here are the normal values for those payload formats that have a normal value. Both type and subtype names are case-insensitive as defined in RFC 6838.
This registry has been closed; it was considered redundant because all RTP payload formats are part of the Media Types. See RFC 9751 for further details.
It was previously stated that registration procedures and a registration template can be found in RFC 4855. As documented in RFC 9751, this is not the case.
