vicon placement tweak, bclistbox select fixes, new ctrl-a/s shortcuts

[goodguy/cinelerra.git] / cinelerra-5.1 / cinelerra / CHANGELOG

11/7/01

Mask feathering and value implemented.  Crash bug in
CWindowMaskGUI::get_keyframe fixed.





11/22/01

Removed memory leak in VirtualConsole.  Another case of base destructor
calling base methods only.

Time average finally implemented. Deinterlace implemented.

Translation in screencapture recording implemented.

AVI parameter editing box.

Drag and drop of assets during an index build doesn't lock up.
Dragging mixtures of audio and video works better.  Better handling of
shared effects which are off.

Batches can be moved up and down the list.





12/6/01

OpenDIVX debugging:

Fixed bugs in decore2: *run = *last = -1; was not copied over from
encore50.

Rewrote bitstream parser in encore2 and decore2 to be more reliable.

Disabled MMX due to crashes in Redhat 7.2.

Discovered decore2 can't do P frames so switched back to decore50.

Renamed header files, symbols to all
in the same program.

Renamed more symbols in mpeg2enc to coexist with opendivx.

To make encore2 work on 64 bit processors:

Typecasted offsets in CompensateBlock and get_ref to (int)

Decore50 still not functional on 64 bit processors.




Implemeneted PNG list output.  Debugged list output and input.

Configuration dialog for OpenDivx in Cinelerra migrated from encore50
to encore2.

Configuration dialog for Vorbis and Vorbis export to Quicktime.

Can use shift-R to render.

DV encoding implemented.  The last libdv library only supported MMX and
B&W.




12/16/01

Moved all OpenDivx support to the encore50 derivative of the encoder.
This appears to do everything that the encore2 derivative could do at
equal or lesser reliability.

Changed bmp argument for decore50 to 3 member array.  Added quant
argument which, when set to nonzero, fixes the quantization.  OpenDivx
with fixed quantization looks 33% better than MPEG-2.

Direct copy rendering for OpenDivx so output of the renderfarm can be
direct copied into a single file.

Moved all theme support into a plugin.  Resources are no longer
compiled in but concatenated to the binaries.  This made compilation
take less time and should theoretically allow more themes to be
supported without increasing resident set size.

Made ports specific to each render node instead of global.  This way
multiple Cinelerra clients can run on the same box without violating
the single thread requirement of new libraries.

Cinelerra daemon forks to background.  Made assets export more
compression parameters to render nodes.

Vorbis decoding in Quicktime without seeking.  The encoding is probably
not going to change anymore but Vorbis doesn't appear seekable.  No-one
is going to use OpenDivx and Vorbis without an endorsement from
Microsoft anyway.







12/22/01

Seeking support for Quicktime/Vorbis.  Support for Vorbis on 64 bit
processors.  Further debugging of Divx.  Quality of 6 yields errors in
output.  Quality of 5 seems to be the maximum.  Changed fourcc from
VBIS to OggS for vorbis.

To make Vorbis work on 64 bit processors:

change sizeof(int) to sizeof(int*) in lib/floor1.c: 263

Menu effects can paste into the timeline.

Changes in label handling when pasting resources.

Statusbar and zoombar resizing restored.

Implemented code to move plugin sets up and down a level.

Improved table of contents support for libmpeg3.  This scans every byte
of the mpeg files and records the location of every keyframe and every
sample of audio.  The table of contents can then be loaded by
Cinelerra, allowing frame accurate editing from mpeg source material.

A memory allocation bug in the Linux kernel crashes the system when
using mpeg3toc on DVD's so forget about transcoding Starwars on a
render farm.  Don't know who discovered that either.







12/28/01

Ignored the warnings and set -ieee for all files in quicktime to fix
floating point exceptions.  This made it twice as slow but it worked.

Floating point exceptions in the following places were fixable with
certain changes:

vorbis_lpc_predict    ->  A return statement before anything is done.
bark_noise_pointmp    ->  noise[i] could be set to 0
bark_noise_hybridmp   ->  noise[i] could be set to 0

Defining VORBIS_IEEE_FLOAT32 seemed to fix mapping0 crashes so the
preceeding changes were backed out.

Loading XML files with multiple video tracks works better.

Linux 2.4.17 handles DVD table of contents operations better but
crashes after 5 hours of reading a DVD.  You'll have to reboot often to
control memory corruption.







1/4/02

Credit for official Microsoft software even though there isn't any
official Microsoft software.

Records to DV again but not under kernels after 2.4.7.

New audio effects:

Frequency table expanded in Units.  This uses real 1/3 octave steps.

Flipped U and V in opendivx encoder so it conforms to YUV order on
disk.

Reconfiguration during audio rendering reenabled.

Constitutive reconfiguration for video turned off.  This was used to
debug the memory leaks.

Icon for Normalize.  Tone generator improvement.





1/18/02

New audio effects:
Compressor


New video effects:
Denoise
Frame to field conversion
Field to frame conversion
Reframe

Video denoise uses the average of an arbitrary number of previous
frames to predict what the value for the next frame should be.  This
can also be used as a threshold effect or a time average.

Optimized time average.




1/25/02

Plugin keyframes loaded from XML.
Correct rendering of plugin keyframes.  Some plugins interpolate.
Most plugin GUI's update when insertion point is moved among keyframes.

Invert audio







2/1/02

Progress windows really cancel instead of just letting you press the
button.

Removed Send and Recieve options from effects.  It was never needed and it
complicated the use of variable track sizes.

First stage of making width and height specific to tracks and renamed
projector size to canvas size.
More interpolation for effects.
Second stage of titler.






2/8/02
Pasting effect keyframes works better.

detects when effects synthesize material.
Independant track sizes can now be changed with a popup menu.
Renderfarm more accurately calculates balanced loads.
Disabled avifile to reduce the debugging noise.
Removed memory leak from Quicktime MPEG-4 decoder.
Slightly optimized resource window updates after loading.

Linux 2.4.17 crashes probably because Cinelerra moves too much memory
around.  We disabled kswapd by putting a return 0; in
/usr/src/linux/mm/vmscan.c.  The operating system seems more stable now.

Enabled deletion of assets and clips from the project.  Also can delete
assets from disk.
Rebuild indices should handle multiple indices if selected.

Rectangle selection in asset window.  The heroine background was
lightened but mind you, the heroine background is a permanent feature.

Latest seeking issue fixed in libmpeg3.  Looking for ways to shift
audio based on the pts.
Compositor window tumblers work better.
More verbose overlays for camera, projector, and output regions, making
it easier to visualize the compositing pipeline.
Easier to use magnifying glass.
Middle mouse button dragging in CWindow works.


new video transitions:
bandslide
bandwipe
slide
wipe
irissquare







2/22/02

Implemented another MPEG-2 bitrate control algorithm.  YUV 4:2:2 MPEG-2
in fixed bitrate modes above 7000000 is recommended for DV footage for
now.

Assets and effects are now sortable in the Resource window.  Text
displays aren't corrupted as much.

Certain EDL load operations honor the labels follow edits setting and
certain load operations insert labels constitutively.

Width and height of tracks load properly.  Adjustments to track width
and height render more often.

Playback automation always restored from undos.

Improved tracking when every frame is played.  Smooth scrolling during
playback is now supported.

Right mouse button doesn't activate selection rectangles anymore.

YUV 4:2:0 Planar -> YUV 4:2:2 Planar color conversion

Renderengine retools the playback configuration for every command instead of
every EDL change.

Integrated IA-32 assembly language jpeg library.







3/15/02

option to Buz output driver.

YUV overlay reenabled.  Only works on commercial NVidia drivers.

Libmpeg3 reads transport streams again.

Dissolve debugged further.

Moving out guicast images.  Implementing defaulttheme and microtheme.












3/22/02

Consolidated audio and video settings into a format dialog.
Made XVideo a separate driver.
Continued improvements of defaulttheme.
Draws MWindow BG and copies top background instead of several MWindow drawing calls.

Re-enabled configurable preloading in Quicktime since moov atoms larger
than 2 M were setting the preload too high.

Frame to field copies two fields into the output instead of line
doubling one field.

Tightened synchronization during recording startup.

CWindow and VWindow timebars implemented.
Timebars in CWindow and VWindow allow a region to be selected for
previewing.

Debugged configuration updates in Synthesizer and Parametric EQ.

Camera translation from the exact top of a frame to less than the full
height really translates instead of squishing.

Reenabled background_pixmap in TrackCanvas to allow faster overlay drawing.

Loading non-XML files doesn't change the output width and height
anymore.  This allows VWindow to change sources without reverting the
output size.

Loop region loads right.

Pan images aren't corrupted anymore.

Clips created when no region is selected take the entire EDL now.

Parametric EQ reenabled.

Shared effects work again when deleted.

Multiple effects per effect row load properly again.

Jumping to next and prev label from CWindow doesn't lock up when playing back.

Instead of synchronizing the absolute position of each fader, the gang
option now changes the relative position of each fader.

Slider tooltips always update before being shown instead of showing
obsolete data.

Got rid of next record label in RecordGUI. Labels set while recording
are finally inserted in the timeline.  The 'l' key triggers a label
when recording.

Paste from one samplerate to another isn't corrupted as much.  Samplerate conversion in paste_edls.

MICROSOFT mouse wheel adjusts all scrollbars, sliders, pots, and
tumblers, perfect for fine adjustments and zooming.  In CWindow and
VWindow it performs frame advance.

Mix2000 update for mouse wheel.





5/17/02

Pulling the official MICROSOFT mouse wheel back zooms out the CWindow
when using the zoom tool.

Brought back the last reflection level in Heroine College Concert Hall
since backwards reverb seems to be popular.

Paste automation resampling implemented.

Splice and overwrite debugged.  Paste_edls doesn't change the VWindow
source during splice and overwrite.  Splice inserts before the in_point
and ignores the out_point.  Overwrite erases between in_point and
out_point.

Dragging asset into VWindow updates the timebar.

Shifting effect handles works better.  Disabled checks not important to
effects.

TIFF and TGA I/O with image sequences.

Reenabled alpha blending.

Changing track titles redraws overlays.
Window is renamed after replacing project.

Shrank threshold in equivalency tests.  It was catching the wrong
in/out points.

Made FloatAutos store bezier curve information.

Got rid of full duplex record options.  Since modern sound drivers
allow single devices to be opened twice this is more easily done by
starting playback on the timeline manually when recording.

Plugin titles updated when track titles change.
Create clip with just in or out point creates something of positive length.
Create clip with no in or out point takes the entire length in VWindow.
Labels enabled in VWindow.
Overwrite doesn't shift effects or labels.
Overwrite overwrites the region between in and out of in and out are different
but overwrites its own length if in and out are identical.

Shifting out point in doesn't delete transitions.

Paste should extend effects when the clipboard has no effects and should
overwrite effects when the clipboard has effects.

Labels are undone during undo after paste.
Video tracks are added to the top of the stack while audio tracks are added
to the bottom of the stack.

Dragging an effect from one track to a zero length track retains the length
of the effect instead of crashing.

Dragging an effect from the Resource Window onto a zero length track doesn't
insert the effect on the track.







6/14/02

Bilinear interpolation from Broadcast 2000 migrated over.  This
averaged more pixels than the standard bilinear interpolation we
upgraded to in 2000.

Mutual exclusion lock for liba52 since liba52 can't run two frame
decodes simultaneously.

Removed double lock from Heroine College Concert Hall.

Correctly detects playable tracks more often.

Bezier curves for fade and zoom.

64 bit mpeg file support.  XMovie plays 64 bit mpeg files.

Variable channel numbers work finally.  Audio pans adjust when channel
count changes.

DV encoding in color works slightly better but still corrupted on the
right side.  The libdv upgrade can't decode of course.

After assessing levels of interest, marketing direction, and
experiencing a CVS erasing filesystem crash we moved forward on the
folding of all code into a single repository.  Moved quicktime,
libmpeg3, xmovie, mix2000, and 2 mpeg multiplexing tools into the
cinelerra tree and renamed the one gigantic tree hvirtual.  The upside
is Cinelerra compilation only requires exporting CFLAGS instead of
hunting down 5 packages and exporting CFLAGS.  The downside is the one
guy who uses Quicktime has to download a bigger package through his
bankrupt ISP's refurbished 1998 reissued cable modem.

Mind you everything except cinelerra and plugins will remain
independant of each other.

While it may work for servers ext3 isn't suitable for desktops which
are constantly shut down and restarted.



6/21/02

DV decoder 0.9.5 migrated.  Not tested for error resilience yet.
Made to_clip not copy all to the temporary clipboard so it wouldn't

Going to next and previous label with scrolling refreshes the compositor.
Drawing of highlight box when dragging over the timeline is more accurate.
Dragging one keyframe beyond another deletes the keyframe like it should.
Bezier keyframes may work better than before.

tracks->get_total_length considers keyframe length as well as edit
length.  This allows keyframe undo for regions where no edits exist.

Update undo routines can be called recursively without corrupting the
undo table.
Undoing and redoing keyframe adjustments works better.

Bilinear reduction with alpha channels fixed.

Memory leak removed from Quicktime udta.

the new clip.

Changing asset sample rate works again.
List boxes updated in AWindow after changing mode.
Interface preferences have options for trimming.

Copy added to CWindow buttons.  Cut removed from VWindow buttons.
Copying always takes session parameters, so it works in VWindow instead
of crashing.

Audio module fragment reduced to support Linux 2.4.18.  Maximum DMA
allocation is no longer supported in 2.4.18 so audio fragments must be
kept below 4096.

Units in freeverb changed to DB.










7/19/02

libmjpeg works on dual CPU systems finally.  Mutually excludes
allocate_temps.  MJPEG files should crash less often.

Changing sample rate of WAV file in Asset window works.
JPEG stills get saved with proper dimensions.
Migrated to RedHat 8.0.
 - e2fsprogs-devel is needed to compile the background render object.

Paste silence and clipboards also shifts effect keyframes properly.
More checks for circular references in shared effects and shared tracks.
Tracking during audio playback without video doesn't run past edge of loop boundaries.
Better keyframing in Titler.
Multiple language encodings in Titler.
Undo of replace project after an effect works.
Frame -> field conversion does line averaging and pixel shifting.
Field -> frame conversion uses pixel shifting.

A lot of patches were rejected.  Some were accepted.  Most of these
coding practices were done in 1997 but abandonned later because of high
maintenance.  To save code size, the memory leak checker shouldn't flag
single allocations as leaks and static pointers shouldn't be
explicitely deleted on exit.


titler-charsets.diff

merged.


cinelerra-loop-patch*

The bugs in loops and audio positioning were fixed another way.


cursor-patch.diff

Too much maintenance in function indirection with no effect.

Explicit declaration of the movement distance requires too much
maintenance.  The move commands were separated for scalability reasons.



mempatch-2.diff


Units::topower was already static.  Patch has no effect and requires
too much maintenance.


mempatch-3.diff:

DefaultTheme is intended to be replaced by a subclass of BC_Theme and
use BC_Theme for all memory management.  No expansion of this file is
maintainable.

ArrayList::aray_delete was merged.

Changes to BC_Meter, BC_Resources require too much maintainence and
have no effect.

static variables in BC_WindowBase prevent different windows in the same
application from having different fonts.

Deletion of pointers in AWindow, CWindow, VWindow, MWindow requires too
much maintenance.

Buttons in AWindow may be used in the future and should not be deleted.

Buttons in editpanel may be used in the future and should not be deleted.

Selections were replaced by masks.  Deleted from VTrack.







mempatch-5.diff

BC_NewFolderThread expansion done differently.
BC_FileBox widget deletion already done by BC_WindowBase.  Too much code for no effect.
BC_ProgressBar::~BC_ProgressBar() implemented.
BC_Resources changes have no effect.
It's already a static object and if the images were overridden, their BC_Theme class would delete the lists.
BC_WindowBase changes were preemptively rejected.
Canvas::~Canvas merged.
CPanel::~CPanel already done by BC_WindowBase.  Too much code.
CWindowGUI::~CWindowGUI mostly done by BC_WindowBase.
MeterPanel::~MeterPanel merged
Module::create_new_attachments merged
StatusBar::~StatusBar already done by BC_SubWindow.
theme.C too much code.
VirtualConsole::~VirtualConsole introduced too many bugs.
ZoomBar::~ZoomBar partially merged.  Mostly done by BC_SubWindow.
DefaultTheme::DeleteVFrames is done by BC_Theme.
title.C fonts is a static variable because it shouldn't be deleted.




mempatch-6.diff
BC_FileBox done differently.  Lock_window is normally used when updating a GUI from a thread.

mempatch-7.diff
VirtualConsole refurbishment was handled differently.

filevorbis.C asymetric fclose patch applied.







mempatch-9.diff

MWindow::load_filenames memory management applied.
Rest has no effect.

mempatch-10.diff

decode_lock is static because it shouldn't be deleted.
Rest has no effect.

Audio and video playback through firewire.  Can't get a playable
audio stream for the camcorder in realtime but the interface is there.

Quicktime: Libraw1394 and grabbing removed.  Didn't serve any purpose
since  playback requires a completely different mechanism than record.

Quicktime, XMovie, Cinelerra: ffmpeg decoder used in MPEG-4.  This
gives slightly faster playback but is lousy at seeking.

More file writing recovery from crashes.

Cinelerra: Module dereferences renderengine less often in nonrealtime
effects where renderengine is 0.

Quicktime: Importing of dvgrab and lavtools AVI files.
Cinelerra: Hitting space rapidly doesn't lock up recording as much.
Cinelerra: Resize Render effect window.
Cinelerra: Changing parameters for PCM file works more often.

Cinelerra: tiff upgraded to 3.1.7
Firehose: Fixed bug in firehose reciever.
Cinelerra: Virtual file system for renderfarm.
 - The filesystem prefix for rendering nodes was decidedly useless so it was
discontinued.
Cinelerra: Time stretch based on overlapping windows instead of FFT.
Cinelerra: Freeze frame has line doubling option.

Integrated mpeg2enc, toolame, lame encoding as libraries.
Toolame refurbishment:
 - converted exit to return in main.
 - put prototypes in filempeg.h
 - created input buffer management.
 - forced stdin at all times
 - created error and eof variables.
 - freq2bark -> toolame_freq2bark
mpeg2enc symbol conflicts:
 - putbits -> mpeg2enc_putbits
 - SmpFrqIndex -> toolame_SmpFrqIndex
 - BitrateIndex -> toolame_BitrateIndex

edit and effect titles stay visible at all times.  We'll see how long
this lasts.

long replaced with int64 wherever possible.  After many years of
assuming long would automatically scale to whatever it was compiled on,
it appears more of a pain than a scalability point in matters of
function overloading.

Default configuration should run on stock Redhat 9.0 system.



Patches:
loop-crush.diff applied
exit-crush.diff too much code for no effect
splash-leak.diff applied
overlay-speedup.diff applied
overlay-speedup2.diff applied
titler-stroke.diff
titler-stroke2.diff applied but disabled due to SMP crash. (crush)
        Added Outline style and tumbler.
        Reduced number of exits due to bounds checking errors.


quicktime_leak.diff applied
small-clean2.diff file may be closed and reopened without calling destructor.

patchbay_free.diff applied but the real problem was PatchBay::update()
        dereferenced non-existent tracks to get the ID.


perspective_alpha_stretch.diff applied
virtualconsole_leak.diff applied but the default destructors seem to be
        getting called.
dvlib_bug_workaround.diff applied
debian_new_dvlib_compile.diff applied

multihead_compositor-1.1.5.diff rejected  The X11 parameter in Playback
preferences is the compositor display.

filexml.diff applied
paste-outpoints.diff needs testing

paste-outpoints.diff rejected.  Broke other paste behavior.  The paste
behavior is not a uniform case but the result of trying behaviors on a
case by case basis and deciding which behavior is the most convenient.
Most of the time what's convenient is not the most scientific.
