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.
Commit 77ab1721 renamed the client binaries; this change updates
.gitignore to follow this change.

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.
when using cairo-glesv2 subsurface rendering code
implicitly calls eglMakeCurrent(dpy, NULL, NULL, ctx)
(since EGL_KHR_surfaceless_context is used), thus,
triangle_frame_callback:eglSwapBuffers returns EGL_BAD_SURFACE
error for all invocations other that the first one
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).
Calls into cairo-gles may change the current context, so it was only by
chance that sometimes we had the proper one as current and updated the
correct texture in surface_attach().
In order to fix this, calling display_acquire_window_surface() before
binding the texture for setup is necessary. However this call has the
side effect of allocating a cairo surface for the window. At flush time,
the existence of this surface will cause an eglSwapBuffers(), even
if no rendering was done to it, leading to undefined contents on the
screen. This happens when the idle redraw task runs while there is a
pending frame callback.
Workaround this by moving the texture setup from surface_attach() to the
redraw handler, so that the cairo surface is only allocated when
redering is done.
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.

We go one utf8 char back and then one forward. Just remember the original
position instead, which also avoids a warning about potentially
dereferencing a NULL return value from next_utf8_char().
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.
