Fix for 2.66a
Screencast could be started twice in a row, but it then also added two handlers
for drawing an overlay circle around mouse cursor. After ending the screencast,
this circle then kept being drawn.
This codec is absolutely needed to generate DCP using OpenDCP,
before that external application to convert JP2 to J2K was used
which slowed down export a lot.
New codec is exposed to image format settings panel and called
Codec. Default one is JP2 which creates files with .jp2 extension,
new one is called J2K which creates with .j2c extension.
Other changes:
- Fixed avi jpeg warning which was treating as error here.
- Made it so extension is detecting from ImageFormatData instead
of image file type, which makes it possible to have different
extension for the same file type depending on it's settings.
IRIS format should still be changed (depending on number of
channels it'll be .bw, .rgb or .rgba extension)
- Default image format settings would be set from image buffer
when re-saving it. Makes it possible to easily open .j2c file
and save it using J2K codec (without this change it'll save as
.jp2 using JP2 codec)
- Screencast: stops working on window resize - crashes movie file output
- Screencast now draws simple brush overlay to indicate mouse cursor.
- Greasepencil now works again to use MMB for view rotates
(and missed proper redraw signal for toolbar, at end of paint)
In fact, color management settings shouldn't be editing from this operator since
screenshot is using OpenGL which is in sRGB space, but fixed issues with Image
Format initialization and added NULL pointer checks.
Replace old color pipeline which was supporting linear/sRGB color spaces
only with OpenColorIO-based pipeline.
This introduces two configurable color spaces:
- Input color space for images and movie clips. This space is used to convert
images/movies from color space in which file is saved to Blender's linear
space (for float images, byte images are not internally converted, only input
space is stored for such images and used later).
This setting could be found in image/clip data block settings.
- Display color space which defines space in which particular display is working.
This settings could be found in scene's Color Management panel.
When render result is being displayed on the screen, apart from converting image
to display space, some additional conversions could happen.
This conversions are:
- View, which defines tone curve applying before display transformation.
These are different ways to view the image on the same display device.
For example it could be used to emulate film view on sRGB display.
- Exposure affects on image exposure before tone map is applied.
- Gamma is post-display gamma correction, could be used to match particular
display gamma.
- RGB curves are user-defined curves which are applying before display
transformation, could be used for different purposes.
All this settings by default are only applying on render result and does not
affect on other images. If some particular image needs to be affected by this
transformation, "View as Render" setting of image data block should be set to
truth. Movie clips are always affected by all display transformations.
This commit also introduces configurable color space in which sequencer is
working. This setting could be found in scene's Color Management panel and
it should be used if such stuff as grading needs to be done in color space
different from sRGB (i.e. when Film view on sRGB display is use, using VD16
space as sequencer's internal space would make grading working in space
which is close to the space using for display).
Some technical notes:
- Image buffer's float buffer is now always in linear space, even if it was
created from 16bit byte images.
- Space of byte buffer is stored in image buffer's rect_colorspace property.
- Profile of image buffer was removed since it's not longer meaningful.
- OpenGL and GLSL is supposed to always work in sRGB space. It is possible
to support other spaces, but it's quite large project which isn't so
much important.
- Legacy Color Management option disabled is emulated by using None display.
It could have some regressions, but there's no clear way to avoid them.
- If OpenColorIO is disabled on build time, it should make blender behaving
in the same way as previous release with color management enabled.

Thanks to Xavier Thomas, Lukas Toene for initial work on OpenColorIO
integration and to Brecht van Lommel for some further development and code/
usecase review!
Only remaining undocumented one is IMAGE_OT_record_composite (not sure what it actually does, nor even whether it’s actually working or not...).
Note that I didn’t bother with operators flagged as OPTYPE_INTERNAL!
Added option display_type to WM_operator_properties_filesel which defines which file
display type (short/list/icons/default) should be used for file browser.
All current operators are using FILE_DEFAULTDISPLAY display type which means display
type will still be calculated based on type of opening file and user preferences
settings. Recover Auto Save operator is now using long display type so file date can
easily be checked now.
Reviewed by Andrea, thanks!
Issue was caused by incorrectly set PTS value frames came form Scene strip renderer.
This value used to be calculated from RenderData current and start frame which
lead to non-uniformuly counting which totally confuses encoder.
Switch append_avi and append_ffmpeg to use current frame from rendering scene
(which was already passing to this functions and was used mostly for logging)
and start frame of rendering scene (it's new parameter added). This allowed to
calculate correct PTS value easily and get rid of global static sframe variable
in writeavi.c file.
Looks like some codecs depends on valid PTS set for frame to encode
frame in right way. PTS is calculating based on current frame number
appending to stream which is stored in render data.
So use rd.cfra in screenshot_startjob() instead of keeping own variable
for reporting current frame number.
Now codecs should be happy and work nice.
