Attention! Rather large sequencer rewrite:
* Implemented layer blending using implicit effects. (works like layers
in "The Gimp" or Photoshop.)
* Fixed Space-Bar start-stop in preview windows.
You can start playback using spacebar within a preview-window and it _works_!
* Fixed Flip Y (didn't work for float)
* Fixed premul (didn't work for float)
* Added IPOs to _all_ tracks. In blend-mode REPLACE it drives the
"mul"-parameter in all other blend modes it drives the effect.
* you can meta single tracks.
* moved "mute track" from "M" to "Shift-M"
* added "Shift-L" for "lock track"
* changed inner workings for Metas. Now all ImBufs have to use the
reference counting mechanism. (Only interesting for coders :)
!!! Really important change, that affects current files!
Since you can mute tracks and now there is real layer blending capabilities
in place, I changed the silly behaviour that chose the output track.
Old behaviour: if we have an effect track visible, use the uppermost effect
track. If there is _no_ effect track visible, use the lowest input track.
New behaviour: always use the uppermost track. With blend modes active:
work our way down starting from the uppermost track to the first
"replace"-mode track. This is the way the gimp, photoshop, basically _all_
other applications work...
So if this change ruins your day: please try to fix your files using
"mute". If this doesn't work out, I can still restore the old behaviour,
but I really hope, that this is _not_ necessary!
Rational: most people won't get affected by this change, since you can't
really do anything usefull with the (old) sequencer without at least one
effect track and then you are on the safe side...
Bugfixes:
* The speed controller changes now dynamically the IPO-curve range to
it's needs. (Frame matching and negative velocities didn't work...
Obviously nobody tried ;-)
* Fixed some redraw bugs. The IPO window is correctly updated if one pushes
the IPO Frame locking button.
Major sequencer rewrite to add Speed Control effect.
Changes:
- Cleaned up large parts of sequence.c removing a lot of unnecessary code.
(We first built old seqar array to decide, what is visible, then build
dependencies with new code, then used old code to iterate through the
strips and deciding using new code what is used and so forth and so on...)
Should be much faster now.
- Now we build the strips recursively thereby elemenating the need of a
seperate dependency calculation.
- Added a Speed-Control effect to change strip speed afterwards.
(Offers global speed as well as IPO-controlled speed.
There are several modes to play with:
- Control by velocity (IPO = velocity where 1.0 is normal speed)
- Control by frame number (IPO = target frame)
- IPO-Value can be rescaled to frame-value, to make frame exact matching
possible. (Matching video tracks to audio tracks with IPOs ;-)
Demo-Blend file is here http://peter.schlaile.de/blender/sequencer/speedcontroltest.blend
Since this was also a Plumiferos request I hope to be mentioned in the
credits ;-)
Enjoy! And please test the new sequencer thoroughly. It is really more like
a rewrite this time.
This adds support for "generator effect strips", which don't need necessarily
an input strip and my version of Matt Ebb's [ #5035 ] 'Solid Color'
sequence strip.
TODO: With a little bit more tweaking it will be possible to make animated
effect plugins and my still unfinished "Bake"-Strip.
For the 'Solid Color'-Effect, to quote Matt:
This is nice and simple, just provides a solid colour that's set in a colour picker in the properties popup. This is something we've needed for a long time, and I got totally sick of having to make 'black.png' and 'white.png' just to do fades, so I coded this.
- blur works again (this was a serious bug in gamwarp...)
- seperates all sequence effects into a seperate file with a clean interface
- thereby fixing some obscure segfaults
- seperates the scope views into a seperate file
- adds float support to all effects and scope views
- removes a bad level call to open_plugin_seq
- FFMPEG seeking improved a lot.
- FFMPEG compiles with debian sarge version cleanly
- Makes hdaudio seek and resample code really work
