Added in metadata encoding capabilities (writer.info.metadata["title"] = "My Title"). Only certain tag names are accepted (see FFmpeg for more on which tags are supported by which codecs).

Experimental codec lookup by name in FFmpegWriter, which should solve a few issues (such as xvid support). Thanks Peter!

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.

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!

Fixed a strange bug related to exporting image sequences. The filename property was not being set on the AVFormatContext. Also fixed a bug when exporting to JPEG image sequences related to max_b_frames and certain codecs.

Big memory leak fixes in FFmpegReader and FrameMapper, and fixed logic in Frame Mapper with regards to special framerate conversions (24, 25, and 30)... which were causing some inadvertent audio drift.

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.

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.

Windows now passes most unit tests. Added header macro to assist on passing correct test media paths to unit tests. Also added a new info parameter has_single_image, which is used to optomize the frame mapper class for images with long durations.

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!

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.

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).
