* Remove all code for Texture and Sequencer plugin system, this never worked in 2.5x / 2.6x and is therefore not needed anymore.
* DNA structures are kept, all read/writefile code is gone.
... instead add scene.sequencer_editor_create / clear, these match id.animation_data_* functions.
- refactor for names, for scene level functions call them BKE_sequencer_*
This adds movieclip input support to the sequencer, thereby making
undistorted and stabilized footage available without a seperate render step.
Also: removes some old cruft code from the sequencer:
* new_tstripdata wasn't used anymore
* StripElems were allocated for SCENE strips on full length, wasting memory
Added a comment, that hopefully makes things a little bit clearer:
StripElems are *only* usefull for MOVIE + IMAGE strips for all other strip
types one can set this pointer to NULL. (If that should cause otherwise
problems, then the code that doesn't check for NULL is to blame!)
Crash was caused by attempting to create strip text from a missed sound datablock.
Actual error happened when this sound datablock was missed, but crash isn't nice
anyway and there were no way to repair scene.
- use more logical names for strings, noticed too many strings called `str` when reviewing name patch.
- pass __func__ macro to uiBeginBlock(), quite a few names were wrong (copy/paste error).
- make ortho grid drawing use vertex arrays
- make perspective view floor drawing cache result of UI_ThemeColorShade so its not called on every line.
- make perspective view floor only loop once on each axis when the grid floor isnt being drawn (was looking over all grid lines for no reason).
- add UI_GetColorPtrShade3ubv() to replace UI_GetColorPtrBlendShade3ubv() when no blending is needed.
Improved waveform drawing in the sequencer.
* Drawing the waveform of a sequencer strip is now independent from whether the sound is cached or not.
* Improved drawing of the waveform in the sequencer (especially speed!).
* Making it possible to vertically zoom more in the sequencer to better see the waveform for lipsync.
* Fixed a bug which crashed blender on loading a sound file via ffmpeg.
Time-scale drawing wasn't respecting the time unit setting.
While working on this, I tried to tweak the grid drawing to a more
common setting. It's hardcoded to show lines at every 25 px = once
every 25 frames, which is only really fine when FPS=25. Anyways, this
works fine enough for the sequencer for now in general usage.
This commit adds an experimental effect strip to the sequencer: "Title
Card".
This is useful for adding simple one-line text section headers or
"title cards" (i.e. title + author/contact details) to video clips,
which is often seen in demo videos accompanying papers and/or
animation tests.
See http://aligorith.blogspot.com/2011/06/gsoc11-simple-title-
cards.html for some more details on usage.
Code notes:
- There are a few things I've done here which will probably need
cleaning up. For instance, the hacks to get threadsafe fonts for
rendering, and also the way I've tried to piggyback the backdrop
drawing on top of the Solid Colour strips (this method was used to
keep changes here minimal, but is quite fragile if things change).
This patch adds adjustment layer tracks to the sequencer and does some cleaning
up of the code.
What's an adjustment layer?
Think of it as an effect track, which takes no explicit input, but alters
the output of everything down the layer stack.
So: you can add several stages of color correction with it.
And: you can even use it with metastrips to group several adjustments together.
