7b6eb9c21b Integration of resvg SVG library (optional during build) (#185)
* Integration of libresvg SVG library (optional during build)

* Major refactor of max_width and max_height for preview optimization

* Fixed many bugs related to preview resizing, with regards to cached frames

* Updating gitlab CI to find RESVGDIR correctly for windows, and adding svgz support

* Updating cmake findresvg module to search for windows locations first, to prevent an issue on our windows builders and updating some CMake output.

* Removing folder path from resvg header, since it could be installed in different named folders. This is an attempt to fix Windows include issues.

* Making call to AV_FREE_FRAME conditional for non windows systems (because it crashes on Windows for seemingly no reason). Needs more investigation.

04e4f63ea8 Calculate max volume of all overlapping clips, and scale clip volume to fit within the 100%, to prevent popping 2018-06-11 12:02:21 -07:00

c95db460d6 Big update! Updating all "long int" frame number types to int64_t, so all 3 OSes will produce the same depth and precision on frame numbers. Also removing variable bitrate support temporarily, since it causes more problems than it solves. 2017-09-28 16:03:01 -05:00

f12ffe692b Migrating tr1 to std, adding C++11 support to build scripts, fixing crash in FFmpegReader (caused by shared_ptr, buffer, and last_video_frame corruption). Much improved stability with this change. Thanks to Craig and Peter for the help! 2017-08-20 17:37:39 -05:00

ec65ca39b3 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

d79994a780 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

c53c9364f3 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

a3ef86a695 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

45f1b8c5ac Making ImageMagick completely optional. This will simplify packaging on Windows and Mac. Also, reprogrammed Display, DisplayWaveform, Save, and Thumbnail methods, which are much faster now (using Qt). 2016-02-23 00:27:03 -06:00

054175ddaa Fixed some audio popping issues related to audio buffer size and also resampling issues inside the FrameMapper class. Also made the Timeline more hardened, if a reader returns an error requesting a frame. 2016-01-30 17:12:41 -06:00

13362393c5 Fixed many more regressions with audio files not passing cover art to the next frame correctly. Seeking issues, and many related issues to detecting missing frames improved. Also fixed a deadlock in certain seeking cases. 2016-01-05 01:59:50 -06:00

bfa050409c 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

c345ae07b7 Fixed the ApplyJsonDiff function to support effects inside clips, which gets a bit tricky. 2015-08-07 23:11:03 -05:00

41dceadd1f Removed Cache::Exists method, which created all sorts of havoc when being called in quick succession (basically a frame might exist a split second before calling Cache::GetFrame, but then be missing when GetFrame is called).
Next Syntax:
frame = Cache::GetFrame(...)
if frame:
   ....

 Also, fixed some issues with MP3 files having the wrong video length detected, and a few other minor issues.

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).

88e65fecef Cleaned up timeline class a bit, and refactored some OpenMP multi-threading support. The timeline GetFrame() method can not fully support OpenMP at the moment, due to nested parallel regions in some conditional ImageMagick function calls. Also better protected the openshot::Clip.GetFrame() call. 2015-03-15 02:28:28 -05:00

b07936e3b2 Added effects processing to a clip, so clips can carry their own independent effects... rather than depend on the timeline. This still needs some refactoring though. 2015-03-14 01:36:13 -05:00

1c3b1f5691 Timeline now supports overlapping clips, and will process them from bottom to top. Only the top layer gets effects applied, which enables overlapping transitions. 2015-02-26 02:31:36 -06:00

86561aed22 Fixed a huge bug when closing a reader and re-opening it. Added some new unit tests to test for that bug, as well as check the ordering of layers and effects. Improved opening and closing of openshot::Clip->Reader() to better support multiple threads. 2015-02-19 01:03:22 -06:00

efa37ea410 Fixed timeline clip sorting to correctly sequence and mix the various layers and clips. 2015-02-18 17:15:03 -06:00
