Fixing Scale Mode (None) in previews ( #182 )
...
* Handle SCALE_NONE mode when optimized for previews (previews are often smaller than the project size)
* Fixing 2 memory leaks (thanks PeterM)

Limiting threads for both FFmpeg and OpenMP (attempting to find a good balance of parallel performance, while not spawning too many threads). Sometimes more is not always better.

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.

Fix bug with FFmpeg > 3.2 flushing frames
...
Final frames stored in buffer need to be flushed/drained so that they
can be written to the video file. Credit to Peter for the update.

Default to AAC audio codec ( #135 )
...
* Adding strict experimental to FFmpegReader and Writer (hopefully allowing all the encoders to be used)
(cherry picked from commit 1bcd1e5)
* init all formats and codecs before checking if valid
(cherry picked from commit 7250226)

Changing some sleep() calls to usleep(), for more accuracy. This is a bit experimental, and hopefully will work on all OSes.

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).

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.
