Jonathan Thomas 066d4818a3 Only apply effects for valid frame objects

bindings

Added new CacheDisk class, which caches frames to the hard drive, dramatically speeding up preview speeds, at the expense of IO operations. New unittests for caching framework. Fixed a few bugs with Frame constructor, which was causing invalid # width & height. Integrated JSON into the cache framework, to quickly share the state of the cache (including ranges of cached frame numbers). Fixed a bug where some Timeline frames could have no audio samples.

effects

Huge refactor of keyframe point handles (bezier quadratic curves) to use CSS-style syntax. Basically, the left and right handles of a point now use percentages, such as 0.0, 1.0, 0.5, 1.0 (between 0 and 1), and become real coordinates based on the value differences between points (in real time). Also simplified the JSON property creation. Also, many unit tests have been updated, because they were actually generating the incorrect values from before... although only slightly in most cases. Now they have correct values from the default bezier handles.

examples

Moved AppendDebugMessage to ZmqLogger, and updated 100+ references to use this new function. Removed debug var from readers/writers, and moved it to ZmqLogger.Enable(true/false). This allows debug output from all classes and functions, without any duplicate code. Also added some additional debug output for video playback and audio readers.

AudioResampler.cpp

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.

2016-08-31 02:02:54 -05:00

2015-08-24 01:05:48 -05:00

EffectBase.cpp

Adding additional meta data to effects Json()

2016-08-18 00:21:43 -05:00

EffectInfo.cpp

Fixed some big performance issues (some which were causing crashes) in effects (Brightness and Saturation), and created a factory class for effects, to reduce redundent code.

2016-08-16 22:40:51 -05:00

FFmpegReader.cpp

Large refactor of detecting missing frames, to make it more accurate and dramatically improve performance for many videos.

2016-12-07 01:06:16 -06:00

FFmpegWriter.cpp

Small change to memory allocation in FFmpegWriter, to be consistent

2016-07-31 15:18:11 -05:00

Frame.cpp

Added new CacheDisk class, which caches frames to the hard drive, dramatically speeding up preview speeds, at the expense of IO operations. New unittests for caching framework. Fixed a few bugs with Frame constructor, which was causing invalid # width & height. Integrated JSON into the cache framework, to quickly share the state of the cache (including ranges of cached frame numbers). Fixed a bug where some Timeline frames could have no audio samples.

2016-09-07 00:40:01 -05:00

FrameMapper.cpp

Added SetMaxSize for image optimizations in QImageReader and FFmpegReader, which lets the timeline pass down the max size to all clips and readers, so they can optionally optimize the size of images (especially useful for optimizing preview performance). Removed convoluted image scaling code in FFmpegReader, and replaced with simpler version. Also, fixed a few regressions from the new Caching code, primarily a crash when reaching the end of the last clip on the timeline.

2016-09-14 04:11:12 -05:00

ImageReader.cpp

Added a new optimized constructor to some readers (FFmpegReader, QtImageReader, ImageReader) to not Open() in the constructor, which dramatically speeds up creating hundreds of Readers (i.e. when opening a project). This is really only useful when inflating the reader with Json right after you instantiate it...

2016-09-16 17:43:26 -05:00

ImageWriter.cpp

Moved AppendDebugMessage to ZmqLogger, and updated 100+ references to use this new function. Removed debug var from readers/writers, and moved it to ZmqLogger.Enable(true/false).

2014-07-11 16:52:14 -05:00

QtImageReader.cpp

Improved image caching logic, to better estimate max image sizes possible, based on clip scale and keyframe settings... so we are always dealing with the smallest possible frame sizes for performance (without losing quality)

2016-09-17 17:14:27 -05:00

QtPlayer.cpp

Fixing cmake build scripts to support 64bit on Windows. Also refactoring some pointer handling to support 64bit on Windows (Linux and Mac have always supported it). Adding instructions for setting up a Windows 64 bit build environment using MSYS2.

2016-08-12 19:15:19 -05:00

ReaderBase.cpp

Added a new optimized constructor to some readers (FFmpegReader, QtImageReader, ImageReader) to not Open() in the constructor, which dramatically speeds up creating hundreds of Readers (i.e. when opening a project). This is really only useful when inflating the reader with Json right after you instantiate it...

2016-09-16 17:43:26 -05:00

RendererBase.cpp

Attempting to fix a race condition when edits are being made to the timeline while frames are being cached and played back. This seems to fix the crashes for me. =)

2015-10-01 14:21:21 -05:00

TextReader.cpp

Improved support for missing frames and invalid PTS (which result in gaps and duplicate frames). Also changed frame number to larger data type, and did some code clean-up and refactoring. Less crashes, and more video support!
