Json::Value JsonValue()
Generate Json::Value for this object.
std::string Json()
Generate JSON string of this object.
CacheMemory()
Default constructor, no max bytes.
std::shared_ptr< openshot::Frame > GetSmallestFrame()
Get the smallest frame number.
Header file for CacheBase class.
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< openshot::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 SetJsonValue(const Json::Value root)
Load Json::Value into this object.
void Add(std::shared_ptr< openshot::Frame > frame)
Add a Frame to the cache.
void Remove(int64_t frame_number)
Remove a specific frame.
void SetJson(const std::string value)
Load JSON string into this object.
int64_t max_bytes
This is the max number of bytes to cache (0 = no limit)
This class is a memory-based cache manager for Frame objects.
