libopenshot

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

Fixed a bug when caching a mask size (a regression from some of our speed improvements)

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.

Qt

Another attempted fix for audio device management. Moving CloseAudioDevice() call to only invoke when quiting OpenShot, and only initializing the JUCE audio manager 1 time. This fixes a audio freeze in Windows when the preview window launches.

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.

CacheDisk.cpp

Reverting and fixing a serious stack smashing error, caused by having a Json::Value in the header file.

2016-09-08 22:18:40 -05:00

CacheMemory.cpp

Fixing invalid cache after editing effect in a clip, and frame accuracy (converting timestamps into frame numbers). This makes frame by frame editing much better.

2017-03-10 00:51:08 -06:00

ChunkReader.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!

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

ChunkWriter.cpp

Update documentation and examples

2015-02-05 00:11:55 -06:00

Clip.cpp

Big improvement with handling invalid video and audio timestamps, defaulting to more sane values (when huge crazy timestamps are detected). Also fixing a bug when disabling video/audio tracks on FrameMappers. Also adding additional bail-out code when stuck searching for a video/audio packet that probably doesn't exist. Added improved "checked" handling, and once 1 frame is detected as invalid, clean out any other invalid ones as well.

2017-05-17 01:17:42 -05:00

ClipBase.cpp

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.

2016-10-19 02:19:07 -05:00

CMakeLists.txt

New cross platform exception handler for libopenshot! Logs basic stacktrace on segmentation fault. This will be a huge help in finding bugs and crashes.

2016-11-03 02:19:48 -05:00

Color.cpp

Fixed a few issues with Color keyframes

2015-10-01 18:51:59 -05:00

Coordinate.cpp

Updating references to frame number / position to long int, there were still quite a few old "int" declarations, which limits the length of frame number. Also, updated precision of KeyFrames to use double (instead of float) for higher precision, which fixed lots of issues with very long videos (since our FrameMapper used a KeyFrame object to create a map to new frames)

2017-01-24 18:39:17 -06:00

CrashHandler.cpp

Fixing incorrect placement of a selection handle.

2016-12-29 18:01:20 -06:00

DecklinkInput.cpp

Adding new CacheBase class. This is the first of many cache related commits, with the goal of building a disk based cache object, to be used by the timeline object if enabled.

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

DecklinkOutput.cpp

Fixed some build errors and updated the Blackmagic DeckLink classes.

2015-02-05 00:08:38 -06:00

DummyReader.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!

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

Fixing Timeline::SetJSON to use a lock, and reopen the reader if already open. This fixes an issue when trying to open another project while the current project is being accessed (i.e. during playback).

2017-05-18 17:04:34 -05:00

FFmpegWriter.cpp

Small change to memory allocation in FFmpegWriter, to be consistent

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

2017-03-10 00:51:08 -06:00

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...

PlayerBase.cpp

Changed license to LGPLv3 for all libopenshot code.

Profiles.cpp

Fixing unicode path issues when loading a Profile() class. Broke when using unicode home directory on Windows.

2017-05-16 17:07:06 -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

Another attempted fix for audio device management. Moving CloseAudioDevice() call to only invoke when quiting OpenShot, and only initializing the JUCE audio manager 1 time. This fixes a audio freeze in Windows when the preview window launches.

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!

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

Timeline.cpp

Fixing Timeline::SetJSON to use a lock, and reopen the reader if already open. This fixes an issue when trying to open another project while the current project is being accessed (i.e. during playback).
