* C: caps inlined flag
|
|
* When C set, first part of payload contains caps definition. Caps definition
|
|
* starts with variable-length length prefix and then a string of that length.
|
|
* the length is encoded in big endian 7 bit chunks, the top 1 bit of a byte
|
|
* is the continuation marker and the 7 next bits the data. A continuation
|
|
* marker of 1 means that the next byte contains more data.
|
|
*
|
|
* CV: caps version, 0 = caps from SDP, 1 - 7 inlined caps
|
|
* D: delta unit buffer
|
|
* ETYPE: type of event. Payload contains the event, prefixed with a
|
|
* variable length field.
|
|
* 0 = NO event
|
|
* 1 = GST_EVENT_TAG
|
|
* 2 = GST_EVENT_CUSTOM_DOWNSTREAM
|
|
* 3 = GST_EVENT_CUSTOM_BOTH
