RTP Payload Format Media Types
- Registration Procedure(s)
-
Registry closed
- Reference
- [RFC4855][RFC-ietf-avtcore-rtp-payload-registry-05]
- 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 [RFC6838]. This registry has been closed as it was considered redundant, as all RTP Payload formats are part of the [Media Types registry]. For further motivation, see [RFC-ietf-avtcore-rtp-payload-registry-05]. It was previously stated that registration procedures and a registration template can be found in [RFC4855]. This is not actually the case, as discussed in [RFC-ietf-avtcore-rtp-payload-registry-05].
