09ce05bbf2 Many improvements for smooth audio playback when 'time' keyframes are used for time remapping.
- Added new Frame::ReverseAudio() helper method - for time keyframe support playing backwards audio
- Fixed math rounding error on time keyframe Resampler, to use the rounded source samples value
- Removed some unused args and Frame audio methods
- Reset FrameMapper resample context when non-adjacent frames are requested
- Correctly reverse Frame audio if a time keyframe is present, and reversing audio
- Rewrite Keyframe::IsIncreasing() function, to give accurate direction of time keyframes at any index (special logic to support first and last indexes)
- Fixed Keyframe unit tests - since logic has changed a bit
- Improved time mapping unit tests
- Replace many c-style casts with static_cast
- Added new sine.wav test file

59d46e59be Large refactor of Clip::GetFrame and time-remapping of audio samples.
- Refactor AudioLocation into own header
- AudioResampler now supports variable channels
- Adding cache back to Clips - to prevent the cost of multiple calls for the same GetFrame() frame, used in time-remapping
- Large refactor of Clip::GetFrame, to prevent multiple code paths, and much improved time-remapping
- Clip's time keyframe now supports Bezier and sub-frame precision - to you can curve audio speed using any curve shape
- Fixing # of audio samples on Clip frame's, based on timeline position (to predictably divide samples per frame)
- New Clip unit tests for time remapping and resampling audio, and reversing audio
- New Frame::GetAudioSamples arg, to allow for reversing the direction of audio samples
- Fix bug in Frame::AddAudioSilence() to correctly cache the # of audio samples
- FrameMapper clean up resample context (when changing frame rate)
- FrameMapper refactor to optimize # of calls to Reader()::GetFrame(), since calls to Clip::GetFrame are quite expensive
- Removing RepeatingFraction functionality from Keyframe object (since it was a bad implementation detail from our previous time remapping)
- Making Keyframe GetDelta method a float, and no longer an int - to allow for more precision on time remapping
- Large amount of white space fixing (to make things consistent)

b612f3339d Replaced ImagMagick with QImage on almost all key methods and classes. Reprogrammed all effects and the entire rendering pipeline to use QImage and QTransforms, primarily for increases in speed and stability. libopenshot is more than 10X faster on many of the most CPU heavy tasks. This was a huge change, and still has a few minor issues relating to BlackMagick Decklink and Text rendering.... which should be resolved very soon.
Also, much work has been done on memory management / leak detection, and optimizations with multi-threading... including a new thread cacher class used by the video playback (which is smoother than ever).

5010f6252a Replaced all copyright and licensing to reflect AGPLv3 license. Also, added a bad ass version header, which is now integrated into CMake as well. A single place to indicate version and ABI/API compatibility. 2014-03-29 18:49:22 -05:00

b74e97c7d2 FIxed some big audio bugs, and finally got the audio reversing correctly working. Now, audio waves are reversed when a time map is moving backwards. There are still some pops and crackles, but I'll fix those later. 2012-10-21 05:29:29 -05:00

67dba0cd67 Fixed the audio resampling by adding a new class called AudioResampler, which maintains state between calls to the JUCE resampler. Maintaining state allows JUCE to remove the discontinuities between the frames, and removes all the pops and crackles.
This is a major commit, and changes many things, including build scripts, new classes, and how the encoder works.
