void SetJsonValue(Json::Value root)
Load Json::JsonValue into this object.
Json::Value JsonValue()
Generate Json::JsonValue for this object.
void Add(std::shared_ptr< Frame > frame)
Add a Frame to the cache.
CacheMemory()
Default constructor, no max bytes.
void SetJson(string value)
Load JSON string into this object.
std::shared_ptr< Frame > GetSmallestFrame()
Get the smallest frame number.
Header file for CacheBase class.
Header file for all Exception classes.
Header file for Frame class.
All cache managers in libopenshot are based on this CacheBase class.
void MoveToFront(int64_t frame_number)
Move frame to front of queue (so it lasts longer)
std::shared_ptr< Frame > GetFrame(int64_t frame_number)
Get a frame from the cache.
void Clear()
Clear the cache of all frames.
int64_t Count()
Count the frames in the queue.
int64_t GetBytes()
Gets the maximum bytes value.
This namespace is the default namespace for all code in the openshot library.
void Remove(int64_t frame_number)
Remove a specific frame.
int64_t max_bytes
This is the max number of bytes to cache (0 = no limit)
string Json()
Get and Set JSON methods.
This class is a memory-based cache manager for Frame objects.
