bd90b8d6c9 ReaderBase: Deprecate SetClip/GetClip names 
- Replacement method names are SetParentClip/GetParentClip
- Old names are retained as deprecated alternates, for now
- libopenshot internal calls (very few) are updated

3c2532b4de Use std::make_shared to allocate shared ptrs 
std::make_shared does in a single allocation what the constructors
for std::shared_ptr usually take at least 2 allocations to do.
May give us an infinitesimal performance/memory improvement.

96d84311c6 OpenMP: Move off deprecated allow_nested boolean 
- 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

dff42011ff Restore default gain when adding audio 
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.

re-encoding algorithm.

e74d71f545 FFmpegReader/Writer: limit hwaccel to FFmpeg 3.4+ 
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+.

22bf6edfba Enhance Json data handling 
- 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

d6a4cb1dec Moving back to SWS_BICUBIC for high quality mode (during export mostly). This provides a sharper image when enlarging images than SWS_LANCZOS, and only has a slight performance disadvantage. 2019-11-17 16:34:50 -06:00
