GStreamer data protocol
|
|
Intended to wrap GstData objects in a line protocol for use with
|
|
pipe / network elements.
|
|
IDEAS-- -- -*for transporting buffers, have a function that creates a header for a given buffer to be written before the buffer.
|
|
This way, you don't lose time creating a GDP buffer from the buffer
|
|
* allow for CRC' ing of the GstBuffer, optionally * have a version number of the protocol * optimizing the header for size is not useful since the GstData structure
|
|
already contains more than 32 bytes anyway, making up half the header size PROTOCOL-- -- ----*1 byte GDP major
|
|
version (0)
|
|
*1 byte GDP minor version (1)
|
|
* 1 byte GDP flags
|
|
* 1 byte GDP data type
|
|
1 for buffer, 2 caps, 65 + for events
|
|
* 4 byte length of "payload"
|
|
* 8 byte timestamp of buffer / event
|
|
* 8 byte duration of buffer
|
|
* 8 byte offset
|
|
* 8 byte offset_end
|
|
* 2 byte buffer data flags * 14 byte future extension (ABI padding)
|
|
*2 byte optional header crc
|
|
* 2 byte optional payload crc
|
|
* (length) payload
|
|
header:60 bytes
|
|
PROTOCOL CHANGELOG-- --
|
|
--------------0.1:added two bytes for buffer flags all numbers use
|
|
network byte ordering.
