13bd272ead Adding new settings class to be used for changing realtime settings used by libopenshot, such as scaling mode for preview vs final render, or hardware decode, etc... 2019-01-09 16:50:40 -06:00

e879188a7d FFmpeg 3 & 4 support, Travis CI support, OpenMP schedule change (#160)
* FFmpeg4 support. Compile warnings fixes. Credit goes to many people, including ferdnyc, peterM, and other awesome folks!

* Adding environment checking to enable/disable omp taskwait after each video/audio frame is processed. This is experimental for some users with crashes.

* Moving `omp taskwait` to after the ProcessVideoPacket() method, since that is the only place it is useful.

* Fixing crashes on missing Clip source file, and changing FFmpeg scaling algorthm from SWS_BILINEAR to  SWS_LANCZOS (for higher quality scaling)

* Update FindFFmpeg.cmake module, and updating build script. Also enabling debug builds.

* Updating experimental travis build script

* Fixed unit test for newer version of FFmpeg (audio resampling)

* Experimental travis multiple jobs

* Adding OMP schedule hint (thanks PeterM), which prevents crashes in some circumstances.

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

179d091005 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. 2016-04-21 01:39:17 -05:00

723bd24e5c Adding new dependency: libzmq (ZeroMQ). Adding a new debug logging class powered by sockets and ZeroMQ, to allow a threadsafe way to communicate debug messages to a client application (i.e. openshot-qt). Also, removing unneeded Sleep.h functions. There will be lots more code utilizing ZeroMQ soon. 2016-04-04 23:09:18 -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

276aae35b3 Improvements to exception handling, including using std::exception base class, and better general purpose exception handling in SWIG with Python. Also fixed an error when thowing exceptions inside OMP regions. 2016-02-02 01:09:02 -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

03c9f06708 Fixed many audio issues with the FFmpegWriter. Planar formats were not being handled correctly. Framesize was also wrong on some formats. Also, added a new method to a Frame to fill with audio silence. Lastly, cleaned up some unused imports and C++ warnings. 2015-08-02 20:32:33 -05:00

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).

ea9885f9a9 Laying the ground work for audio mapping (resampling and changing channel layouts) for the openshot::FrameMapper. This is important for use with the Timeline, that all clips have a common frame rate, sample rate, and channel layout. 2015-02-26 17:33:09 -06:00

ff60450f4f Completely rewrote audio encoding API (old one was depreciated)
Integrated new debug output, which makes troubleshooting issues much easier
Simplified the Writer API calls (some methods now get automatically called if needed). Now a few simple methods can write an entire video file.

e073ad89f5 Fixed many issues with the QtPlayer and related classes. Now the VideoRenderer can be passed through SWIG and connected to a PyQt application and handle display signals for each frame. Also, refactored some OpenMP settings into its own header. 2014-04-02 16:48:27 -05:00

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
