<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.

<description summary="a frame ready for copy">
|
|
This object represents a single frame.
|
|
|
|
When created, a series of buffer events will be sent, each representing a
|
|
supported buffer type. The "buffer_done" event is sent afterwards to
|
|
indicate that all supported buffer types have been enumerated. 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.
|
|
|
|
For objects version 2 or lower, wl_shm buffers are always supported, ie.
|
|
the "buffer" event is guaranteed to be sent.
|
|
|
|
If the capture failed, the "failed" event is sent. This can happen anytime
|
|
before the "ready" event.
|
|
|
|
Once either a "ready" or a "failed" event is received, the client should
|
|
destroy the frame.

Called as soon as the frame is copied, indicating it is available

at.

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

each component being an unsigned 32-bit value. Whole seconds are in
|
|
tv_sec which is a 64-bit value combined from tv_sec_hi and tv_sec_lo,
|
|
and the additional fractional part in tv_nsec as nanoseconds. Hence,
|
|
for valid timestamps tv_nsec must be in [0, 999999999]. The seconds part
|
|
may have an arbitrary offset at start.
|
|
|
|
After receiving this event, the client should destroy the object.
