This patch adds a feature to the DRM backend that uses libva for
encoding the screen contents in H.264. Screen recording can be
activated by pressing mod-shift-space q. A file named capture.h264
will be created in the current directory, which can be muxed into
an MP4 file with gstreamer using
gst-launch filesrc location=capture.h264 ! h264parse ! mp4mux ! \
filesink location=file.mp4
This is limitted to the DRM compositor in order to avoid a copy when
submitting the front buffer to libva. The code in vaapi-recorder.c
takes a dma_buf fd referencing it, does a colorspace conversion using
the video post processing pipeline and then uses that as input to the
encoder.
I'm sending this now so I get comments, but this is not ready for
prime time yet. I have a somewhat consistent GPU hang when using
i915 with SandyBridge. Sometimes a page flip never completes. If you
want to try this anyway and your system get stuck, you might need to
run the following:
# echo 1 > /sys/kernel/debug/dri/0/i915_wedged
After that, alt-sysrq [rv] should work.
Once that's fixed it would also be good to make the parameters used by
the encoder more flexible. For now the QP parameter is hardcoded to 0
and we have only I and P frames (no B frames), which causes the
resulting files to be very large.
GL_UNSIGNED_INT is only supported when GL_OES_element_index_uint is
available (mesa implements that extension). We don't need 32-bit
indices, so just use GL_UNSIGNED_SHORT.
We don't always get both an X and an Y event in a SYN report, so we end
up transforming the coordinate we don't get twice. For example, if we
only receive an ABS_X event, we transform the already transformed
device->abs.y again in transform_absolute() when applying the calibration.
Now that we use AC_SYS_LARGEFILE, we need to pull in config.h at least
whereever we use mmap(). Fixes at least the test-suite and simple-shm
on 32 bit systems.
window->x/y is the coordinate of the top-level surface (whether that's
the frame window or an override-redirect window) and the wayland surface
should be placed there, without the t->margin offset.
The coordinate transformation was broken (worked for first output where
output->x/y was 0,0, broke on all other outputs). We can just use
surface->geometry.x/y directly. We can't use the full transformation,
the best we can do is to move the X window to the geometry.x/y location.
Get rid of the static old_sx/sy hack as well.
We only get configure notify for toplevel (frame or override-redirect window)
and those are the cases where we want to update window->x/y. The way the
code worked, we'd exit immeidately in those cases and window->x/y would
not be updated.
This patch fixes a bug found by Marek Romanowic: the RDP peer output must
be enabled by default, or we have to unfocus/focus the RDP client window to
have disable/enable output messages sent (and finally receive updates).
config.h includes were missing in a few files, including input.c, the
lack of which caused the X11 backend to segfault instantly due to not
having an xkbcommon context.

This allows a surface to live on after its resource has been
destroyed. The ref-count can be increased in a resource destroy signal
listener, to keep the surface around for a destroy animation, for example.
We don't handle them in any way now and having your steering wheel move
the cursor isn't useful. Applications can still open evdev devices and
access them directly like they already do.
This patch adds 3 new options to weston.ini to allow
the user to change default constant_accel_factor,
min_accel_factor and max_accel_factor. If no options
are set, it falls back using defaults as it did before.
v2: create weston_config_section_get_double and use it
instead of manualy converting string to double.
v3: add default values in weston_config_get_double
instead of using conditionals.
v4: don't pass diagonal as pointer.
Other clients of an evdev device need to have the events they receive
be separated, in moment in time, from other events by an EV_SYN/
SYN_REPORT. This is the responsibility of the client who writes events
into the stream.
This removes the use of wl_client_get_display() where the client is
derived from the focussed resource. This starts the removal of the
assumption of a single resource on a client that would be notified about
events on the focussed surface.
device->mt.slot is uninitialized when we're not receiving the
evdev slot events. Always use ID 0 as we do when we generate the
touch down and motion events.
The current code works if pw->pw_shell is bash because:
"If the shell is started with the effective user (group) id not equal to
the real user (group) id, and the -p option is not supplied, these actions
are taken and the effective user id is set to the real user id."
Thus, for bash, weston's EUID == UID.
For zsh, the -p option "is enabled automatically on startup if the effective
user (group) ID is not equal to the real user (group) ID."
Thus, weston's EUID = 0, and if pw_shell is zsh, /run/user/$UID/wayland-0 is
created with euid root and not writeable by the user, causing all clients to
fail.
Fix this by always dropping privileges to the user.
Regression introduced in 636156d.
For touchpads, device->dispatch is set up when exiting
evdev_handle_device() and a potential source for a memleak.
This can't actually happen at the moment, as evdev_handle_device() won't
fail for touchpads after setting up the dispatch but prevent this from
happening in the future.
If touches are already present on the device, absinfo has the currently
active touch slot. There's a race condition where the slot may change before
we enable the fd and we thus miss out on the ABS_MT_SLOT event. It's still
slightly more correct than assuming whatever comes next is slot 0.
For Protocol B devices, mtdev merely routes the events and is not needed.
For Protocol A devices, mtdev is needed, so fail for those devices now if we
mtdev fails.
mtdev as currently used in weston is a noop. mtdev's purpose is to convert
Protocol A devices (without ABS_MT_SLOT) to Protocol B devices (slots).
For Protocol B devices mtdev merely routes the events, so checking for
slots and then using mtdev based on that adds no functionality.
Check for ABS_MT_POSITION_X/Y instead and use that to categorise a device
as MT device. mtdev will provide us with a slotted protocol for all devices.
