Functions | |
AVFrame * | av_frame_alloc (void) |
Allocate an AVFrame and set its fields to default values. More... | |
void | av_frame_free (AVFrame **frame) |
Free the frame and any dynamically allocated objects in it, e.g. More... | |
int | av_frame_ref (AVFrame *dst, const AVFrame *src) |
Set up a new reference to the data described by the source frame. More... | |
AVFrame * | av_frame_clone (const AVFrame *src) |
Create a new frame that references the same data as src. More... | |
void | av_frame_unref (AVFrame *frame) |
Unreference all the buffers referenced by frame and reset the frame fields. More... | |
void | av_frame_move_ref (AVFrame *dst, AVFrame *src) |
Move everythnig contained in src to dst and reset src. More... | |
int | av_frame_get_buffer (AVFrame *frame, int align) |
Allocate new buffer(s) for audio or video data. More... | |
int | av_frame_is_writable (AVFrame *frame) |
Check if the frame data is writable. More... | |
int | av_frame_make_writable (AVFrame *frame) |
Ensure that the frame data is writable, avoiding data copy if possible. More... | |
int | av_frame_copy (AVFrame *dst, const AVFrame *src) |
Copy the frame data from src to dst. More... | |
int | av_frame_copy_props (AVFrame *dst, const AVFrame *src) |
Copy only "metadata" fields from src to dst. More... | |
AVBufferRef * | av_frame_get_plane_buffer (AVFrame *frame, int plane) |
Get the buffer reference a given data plane is stored in. More... | |
AVFrameSideData * | av_frame_new_side_data (AVFrame *frame, enum AVFrameSideDataType type, int size) |
Add a new side data to a frame. More... | |
AVFrameSideData * | av_frame_get_side_data (const AVFrame *frame, enum AVFrameSideDataType type) |
void | av_frame_remove_side_data (AVFrame *frame, enum AVFrameSideDataType type) |
If side data of the supplied type exists in the frame, free it and remove it from the frame. More... | |
