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