This class is contains settings used by libopenshot (and can be safely toggled at any point)
int DE_LIMIT_WIDTH_MAX
Maximum columns that hardware decode can handle.
int OMP_THREADS
Number of threads of OpenMP.
std::string PLAYBACK_AUDIO_DEVICE_NAME
The audio device name to use during playback.
std::string PLAYBACK_AUDIO_DEVICE_TYPE
The device type for the playback audio devices.
int HW_DE_DEVICE_SET
Which GPU to use to decode (0 is the first)
int DE_LIMIT_HEIGHT_MAX
Maximum rows that hardware decode can handle.
static Settings * Instance()
Create or get an instance of this logger singleton (invoke the class with this method)
int VIDEO_CACHE_MIN_PREROLL_FRAMES
Minimum number of frames to cache before playback begins.
int HARDWARE_DECODER
Use video codec for faster video decoding (if supported)
bool HIGH_QUALITY_SCALING

int VIDEO_CACHE_MAX_FRAMES
Max number of frames (when paused) to cache for playback.
int FF_THREADS
Number of threads that ffmpeg uses.
float VIDEO_CACHE_PERCENT_AHEAD
Percentage of cache in front of the playhead (0.0 to 1.0)
bool ENABLE_PLAYBACK_CACHING
Enable/Disable the cache thread to pre-fetch and cache video frames before we need them.
int HW_EN_DEVICE_SET
Which GPU to use to encode (0 is the first)
int VIDEO_CACHE_MAX_PREROLL_FRAMES
Max number of frames (ahead of playhead) to cache during playback.
bool DEBUG_TO_STDERR
