This class is a memory-based cache manager for Frame objects.
This abstract class is the base class, used by all clips in libopenshot.
float End() const
Get end position (in seconds) of clip (trim end of video)
float Start() const
Get start position (in seconds) of clip (trim start of video)
float start
The position in seconds to start playing (used to trim the beginning of a clip)
float Duration() const
Get the length of this clip (in seconds)

std::string previous_properties
This string contains the previous JSON properties.
Json::Value add_property_json(std::string name, float value, std::string type, std::string memo, const Keyframe *keyframe, float min_value, float max_value, bool readonly, int64_t requested_frame) const
Generate JSON for a property.
A Keyframe is a collection of Point instances, which is used to vary a number or property over time.
This class represents a timeline (used for building generic timeline implementations)
This namespace is the default namespace for all code in the openshot library.
