- Also removed "crop" from Clip class, as it was never implmeneted correctly, and we have a fully functional "crop" effect when needed
- Added caching to Clip class, to optimize previewing of cached frames (much faster than previous)
- Replacement method names are SetParentClip/GetParentClip
- Old names are retained as deprecated alternates, for now
- libopenshot internal calls (very few) are updated
ReaderBase.cpp: Remove (Set,Get)Clip
- Replacement openmp_set_max_active_levels() takes an int argument
- In OpenMP 5.0 it can be set to openmp_get_supported_active_levels()
- Below 5.0, we just set it to our processor count
- Move configuration of OpenMP from ad-hoc locations to constructors
for FFmpegWriter/Reader and Timeline
Incorrect conversion of float to int16_t caused distortion that was
mistakenly perceived as clipping. Now because the convertion was fixed,
there is no more sense to reduce input gain of the source.
Add a new #define HAVE_HW_ACCEL, which is only set on FFmpeg 3.4+,
and use that to restrict the use of hw-accel features, leaving
IS_FFMPEG_3_2 to determine only whether code is compatible with
FFmpeg 3.2+.
- Parsing from string to Json::Value is now done by utility function
openshot::stringToJson() in Json.cpp, all SetJson() methods call it.
- Expand use of const member functions and args where appropriate.
- Use std::to_string() to format int/float values as strings.
- Correct mentions of nonexistent Json::JsonValue type in docstrings
