<description summary="screen content capturing on client buffers">
|
||||||
|
This protocol allows clients to ask the compositor to copy part of the
|
||||||
|
screen content to a client buffer.
|
||||||
|
|
||||||
|
Warning! The protocol described in this file is experimental and
|
||||||
|
backward incompatible changes may be made. Backward compatible changes
|
||||||
|
may be added together with the corresponding interface version bump.
|
||||||
|
Backward incompatible changes are done by bumping the version number in
|
||||||
|
the protocol and interface names and resetting the interface version.
|
||||||
|
Once the protocol is to be declared stable, the 'z' prefix and the
|
||||||
|
version number in the protocol and interface names are removed and the
|
||||||
|
interface version number is reset.

This object represents a single frame.

When created, a "buffer" event will be sent. The client will then be able

to send a "copy" request. If the capture is successful, the compositor
|
||||||
|
will send a "flags" followed by a "ready" event.
|
||||||
|
|
||||||
|
If the capture failed, the "failed" event is sent. This can happen anytime
|
||||||
|
before the "ready" event.

The timestamp is expressed as tv_sec_hi, tv_sec_lo, tv_nsec triples,

tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo,

for valid timestamps tv_nsec must be in [0, 999999999]. The seconds part
|

may have an arbitrary offset at start.
