This fixes one part of [#27353] VSE crashes on large M4V
StripData was alloced in full length for MOVIE and SOUND-tracks, which only
use the first element for filename storage. (StripData as an array is only
used in IMAGE strips).
Fixed the crash and documented accordingly.
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.
Fixes Fix for [#25713] VSE shows and renders wrong straight alpha gradient even after convert to pr
(see revision: 34540, fix by Janne)
By not breaking the seqcache interface API.
Added comments to header file, so that it is easier to understand, how the
cache API is supposed to work.
was not recursively restoring sound strips on paste.
also found many duplicate functions were defining the transform mode as in int but getting as an enum, use enum for both now.
we cant ensure that a requested buffer can be allocated so report opengl errors when failing to allocate the buffer (rather then printing to console).
this is common enough and generic error isn't too helpful to users.
Was trying to free audio data from sequencer strips that don't even have audio. Corrected the error in several ways so this will definitely not happen again :-)
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
* Caching of the start and end stills were just referencing the original imbuf (which got premultiplied after the caching), so as a result most of the time the premul was applied twice.
* Now the start and end stills are stored in the cache as duplicates of the original (non modified) imbuf.
- made theme colors for mesh edge len & face angle/area display.
- use %g rather then %f for float display, trims unneeded zeros.
- store cached 2d and 3d text color as bytes rather then floats, compare when drawing to avoid setting the context.
- use unsigned char for more color functions, avoids casting to glColorubv().
Sequence effect rendering of color generator did some rather strange
fall through, because of a missing break statement. (Noone got hurt, but
better add that break, just in case)
[#25011] Opacity IPO not refreshing with still images
(should be better named: animation of any prefiltering parameters using
still images didn't work out as expected)
And this issue by private mail by Ton:
"I tried to debug a memory-free error; very simple case:
- add image strip
- click on strip at 2 places
- quit blender"
* Rendering a scene strip updated all animation data to it's frame, so fcurves were left with the wrong value.
* Now the animation data is recalculated to original frame after rendering each scene strip.
This fixes Orig Dimension display (mostly).
* orx, ory both didn't get calculated, if dimension already matched
* putting them into Strip instead of StripData ment, that using images
of different dimensions in one strip could lead to incorrect results
Still TODO: on file open, timeline display happens before preview
display which means: orig_width and height are calculated after the
first draw of N-keys dialog. You have to hit refresh (or scrub one
frame) to get the right values displayed.
* documented and rewrote the render interface of the sequencer.
(now, the geometry / render_type / etc. settings are stored within a
seperate structure called SeqRenderData that is passed within the code.)
* that fixes
* cache problems, since the caching system didn't keep track of
proxy files vs. final renders.
* is a necessary step, to bring back frame blending in speed effect
(the SeqRenderData structure elements are already there)
* will make motion blur render options available within the sequencer!
* this patch also fixes:
* "easy retiming" using speed effects. (in Blender 2.49, you could
add a speed effect and resize the source track to retime it to that
length)
* adds labels for the Original dimensions for Image + Movie tracks
(worked in 2.49, too)
The main reason to have this is so renders can be scripted to write to a specific file without having to do annoying tricks like set a dummy start/end frame range, render an animation and work out the current frame image will be written to, then rename after rendering.
Also made some 'char *' args into 'const char *'
also known as: broken multicam strip caused by other fix.
Calculated render_size where it belongs (within the glow effect) and
restored old functionality.
also: renamed render_size to preview_render_size at all relevant places,
where the naming wasn't used correctly.
Hopefully it's now a little bit more clear.
render_size := render size from scene (just rescales width/height)
preview_render_size := preview render size from sequencer preview,
controls the resolution and the use of sequencer proxy sources
* The logic in some parts of the sequencer code was rather cryptic, so I cleaned it up a bit.
* There should be no functional changes what so ever from these changes.
* This fix is really only a bandage, as the underlying issue is that sequencer preview render doesn't yet use the job system.
* The sequencer preview can start a full render of the scene, and this can collide with other preview/actual renders in many cases.
* Drawing the sequencer preview is now disabled when an other render is in progress, but the sequence preview rendering could have already been started before the other render, so this doesn't really fix anything.
* For now only OpenGL rendering can be used for the sequencer preview reliably until it's reimplemented using the job system.
* Using the job system in the future can handle the clashes between different renders properly and will give users a nice progress bar to indicate something is happening while the preview is recalculated.
