This commit basically implements frames prefetching for
movie clip datablock.
Number of frames to be prefetched is controlled in User
Preferences, System tab, Prefetch Frames option.
Currently prefetching is destructive-less for movie cache,
meaning mo frames will be removed from the cache when while
prefetching. This is because it's half of simplier to
implement, but it also makes sense from tracking point of
view -- we could want to playback in both directions and
removing frames from behind time cursor is not always a
good idea.
Anyway, smarter prefetching strategy could be developed
later.
Some implementation notes:
- Added MEM_CacheLimiter_get_memory_in_use function to get
memory usage of specified memory limiter.
- Fixed prototype of MEM_CacheLimiter_get_maximum which
was simply wrong (used wrong data type for output).
- Added some utility functions to movie clip and movie
cache for direct cache interaction and obtaining cache
statistics.
- Prefetching is implemented using general jobs system.
which is invoking from clip draw function.
- Prefetcing will stop as soon other job or playback starts.
This is done from performance point of view. Jobs will
likely require lots of CPU power and better to provide
whole CPU to it.
Playback is a bit more complicated case. For jpeg sequence
playback prefetching while paying back is nice. But trying
to prefetch heavy exr images and doing color space
conversion slows down both playback and prefetching.
TODO:
- Think of better policy of dealing with already cached frames
(like when cached frames from other clips prevents frames
from current clip to be prefetched)
- Currently a bit funky redraw notification happens from
prefetch job. Perhaps own ND_ is better to have here.
- Hiding clip while prefetch is active in theory shall stop
prefetching job.
- Having multiple clips opened on file load will prefetch
frames for only one of them.
This means you can for example, uv unwrap in quad-view and change settings in the toolbar without defaulting back to the first quad-view region available.
This may be displayed to the user later, for now this is set on executing registrable operators.
It introduces a new (py-extendable and registrable) RNA type, UIList (roughly similar to Panel one), which currently contains only "standard" list's scroll pos and size (but may be expended to include e.g. some filtering data, etc.). This now makes lists completely independent from Panels!
This UIList has a draw_item callback which allows to customize items' drawing from python, that all addons can now use. Incidentally, this also greatly simplifies the C code of this widget, as we do not code any "special case" here anymore!
To make all this work, other changes were also necessary:
* Now all buttons (uiBut struct) have a 'custom_data' void pointer, used currently to store the uiList struct associated with a given uiLayoutListBox.
* DynamicPaintSurface now exposes a new bool, use_color_preview (readonly), saying whether that surface has some 3D view preview data or not.
* UILayout class has now four new (static) functions, to get the actual icon of any RNA object (important e.g. with materials or textures), and to get an enum item's UI name, description and icon.
* UILayout's label() func now takes an optional 'icon_value' integer parameter, which if not zero will override the 'icon' one (mandatory to use "custom" icons as generated for material/texture/... previews).
Note: not sure whether we should add that one to all UILayout's prop funcs?
Note: will update addons using template list asap.
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)
Nice formatted version (pictures soon):

Short list of main changes:
- Transparent region option (over main region), added code to blend in/out such panels.
- Min size window now 640 x 480
- Fixed DPI for ui - lots of cleanup and changes everywhere. Icon image need correct size still, layer-in-use icon needs remake.
- Macbook retina support, use command line --no-native-pixels to disable it
- Timeline Marker label was drawing wrong
- Trackpad and magic mouse: supports zoom (hold ctrl)
- Fix for splash position: removed ghost function and made window size update after creation immediate
- Fast undo buffer save now adds UI as well. Could be checked for regular file save even...
Quit.blend and temp file saving use this now.
- Dixed filename in window on reading quit.blend or temp saves, and they now add a warning in window title: "(Recovered)"
- New Userpref option "Keep Session" - this always saves quit.blend, and loads on start.
This allows keeping UI and data without actual saves, until you actually save.
When you load startup.blend and quit, it recognises the quit.blend as a startup (no file name in header)
- Added 3D view copy/paste buffers (selected objects). Shortcuts ctrl-c, ctrl-v (OSX, cmd-c, cmd-v).
Coded partial file saving for it. Could be used for other purposes. Todo: use OS clipboards.
- User preferences (themes, keymaps, user settings) now can be saved as a separate file.
Old option is called "Save Startup File" the new one "Save User Settings".
To visualise this difference, the 'save startup file' button has been removed from user preferences window. That option is available as CTRL+U and in File menu still.
- OSX: fixed bug that stopped giving mouse events outside window.
This also fixes "Continuous Grab" for OSX. (error since 2009)
adding meshes were scaling the user input values so the distance on the button didnt relate to the scale of the object added.
Now use an invoke function that scales unset default values.
Was own regression when was solving conflict between sequencer preview
and compositor jobs. Made it so now only compositor jobs are being
killed from sequencer preview.
When blending shape key, opening the popup didnt execute anything - making it so pressing a button would update the result even if the value didnt change.
Fluid sim would stop or crash with node editor.
Bug was a real bad one - the code for giving out WM jobs was messed up for long.
It was giving a running fluid job to the compositer even... tsk!
I will go over jobs code carefully next days to see if it all behaves. Now it
allows per owner multiple jobs, provided it has different job_type set.
Also fixed: preview renders (material) were deadslow once a while - caused
by icon render setting miniature tile render sizes. Now it's fast again,
but there are still 3 icon jobs running per UI change... need to check what.
comparing keymaps was too sloppy or too strict, now sloppy keymap comparison works by setting all the operator
properties to their default values if they are not already set, then compare this with the keymap item (ignoring values missing from either one).
... this way any non default keymap setting wont match with an operator menu item which doesnt set this operator at all (a problem sighted in this bug report).
developer notes:
- IDP_EqualsProperties_ex() function adds an argument to treat missing members of either group to act as if there is a match.
- WM_operator_properties_default() function to reset RNA values to their defaults.
- add IDP_spit(), debug only function to print out ID properties.
Screencast recording stopped on a undo/redo. This was because all thread jobs
were killed then. Now it leaves screen jobs (screen cast) running, that's
data that doesn't change on undos.
Also renamed jobs_stop_all() to jobs_kill_all() - it terminates threads.
Add an optional ghost argument to set the new mouse location when un-grabbing. - without this the mouse would flicker at the old location before moving to the new location - when using the color picker for eg.
Change operator previous settings initialization not to use the redo stack since this gets cleared and it means only redo operators can re-use last settings.
now this works for import/export as well.
added some missing functions too - which are not used yep but should be there for api completeness.
* CDDM_set_mloop
* CDDM_set_mpoly
* BLI_mempool_count
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!
details
- uses redo stack to get recent settings from.
- adds a flag to IDProperties so RNA_property_is_set() can return false even if the property is exists.
- PROP_SKIP_SAVE option skips these settings from getting reset (as with presets).
