ecore_evas_convert: Add -e/--encoding option
This uses directly the encoding parameter.
For now, used only by the TGV saver, but there is no other way
to specify between ETC1 and ETC2. And we don't have a mixed ETC1+2
mode (yet).
@feature
We prefer ETC2 textures when ETC2 support has been detected.
According to the spec, glCompressedTexSubImage2D should work
for ETC2.
Try even with ETC1. This may fail at runtime. The fallback path
is very dubious right now but without a proper test case I'm
not sure which approach to take.
We can also imagine cases where the GPU supports TexSubImage for
ETC1 but ETC2 is not supported at all. This will need testing, as
this case is not handled.
@feature
Since rg_etc1 now outputs proper BGRA data, the shaders should not
swizzle the colors around. Stick to the normal fragment shaders.
Note: This is not tested.
This symbol should be part of the loaded libraries, can be found
using dlsym, even if eglGetProcAddress() returns NULL.
Add etc1 flag in the debug output.

evas_gl_common_buffer_dump can be used to dump all frames into
a series of PNG files. But the filename contained some garbage
characters (and potential segv, too).
(cherry picked from commit a0f886138ed5a28d0d1596df3b805fca06d1ae31)
It is not necessary to dynamically link to glReadPixels since
this is not an extension. This code wouldn't even work on some
devices.
Also, the pixels returned are not premultiplied (yeah >_<)
And some devices (EGL) don't support GL_BGRA... so glReadPixels
would just fail and not fill in the pixels. Conversion is required.
This will be needed by the filters for proxy rendering,
for textures and maps (displacement).
Add new engine functions to unleash the (sluggish) power of glReadPixels.
The idea is to be able to bypass glReadPixels later, so 3 new APIs are
added:
- surface_lock
- surface_read_pixels
- surface_unlock
They must be called in that order.
Note (for history):
glReadPixels was always getting the wrong data during first draw,
but the right data during a redraw...
Why? Well simply because for OpenGL itself, the image had never
been drawn in teh first place! Only the Evas GL context knew
about the image drawing, as it was queued somewhere in the pipe.
One line solution: Call evas_gl_common_context_flush before
doing anything else.
When running in direct rendering mode, properly support partial
rendering if the extension is properly supported.
Also, fixed the SwapBufferwWithDamage rectangle coordinate bug.
It wasn't properly y-inverted before.
At least on recent mesa (since commit 9f07ca11c17), it will find the
mentioned symbols but they won't really work, leading to error messages,
and possibly some other errors. So far, I just ifdef'ed the
glGenFramebuffer and glBindFramebuffer functions, but it may require
others to be ifdef'ed too.
This is just a workaround, to fix https://phab.enlightenment.org/T246.
Added a feature to dump out a png image before calling SwapBuffers.
To turn on the feature, use the following env vars.
EVAS_GL_SWAP_BUFFER_DEBUG_DIR="dir_name" sets the name of the directory
that the files will be output to and enables the debug mode.
EVAS_GL_SWAP_BUFFER_DEBUG_ALWAYS=1 will enable the writing of the
files every frame. This in effect turns on the swap_buffer_debug
variable, which can be set on or off in gdb for debugging. This will
allow dumping of certain frames without having to dump out a ton of
files to track down one frame.
NOTE: when using Evas_Object image preload infrastructure the GL texture
upload was uploaded from the main loop during the rendering stage. This
could lead to some frame drop during fast animation due to the time needed
to upload that texture.
This patch fix this problem by uploading a small texture quickly (16x16)
and waiting for going back to the main loop to be able to use the same GL
context from another thread to do the texture upload asynchronously without
blocking the main loop.
it seems glmapbuffer can be nasty overhead on some drivers, so go back
to gldrawarrays by default until such a time as we know a lot more...
i'm looking at YOU nvidia! YOU!
num size.. and alloc size is much bigger as it makes room for 1024
quads per alloc increase (6*1024 vertexes etc.). literally this drops
e17's cpu usage while compositing stuff by 40%...at least in my test
case.
downscaling. This makes quality much better and "at best"
equates to a 16 point sample (2x2 linear interpolation samples,
where a linear interpolation sample equates to a 2x2 sample).
This will have perfomance impact, but the quality is worth it and
makes it closer to software downscaling in quality. It supports
2x2, 2x1 and 1x2 oversampling. YUV not done, nor image mask
(font shaders not needed).
I've tested make -j 3 install and it works nicely
I've tested expedite with software and opengl xlib,
and it works. Not tested other engines, so please
report any problems (engines or other) on the ML.
TODO: examples and tests, I'll add them later
ISSUE: Eina_Unicode size check. It indirectly depends on
eina_config.h, which is created at the end of the
configure script. So its size is always 0. I don't
know how that size is used, so I can't do a lot,
for now.
