Functions | |
static void | get_frame_defaults (AVFrame *frame) |
static void | free_side_data (AVFrameSideData **ptr_sd) |
static void | wipe_side_data (AVFrame *frame) |
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... | |
static int | get_video_buffer (AVFrame *frame, int align) |
static int | get_audio_buffer (AVFrame *frame, int align) |
int | av_frame_get_buffer (AVFrame *frame, int align) |
Allocate new buffer(s) for audio or video data. More... | |
static int | frame_copy_props (AVFrame *dst, const AVFrame *src, int force_copy) |
int | av_frame_ref (AVFrame *dst, const AVFrame *src) |
Set up a new reference to the data described by the source frame. More... | |
int | av_frame_replace (AVFrame *dst, const AVFrame *src) |
Ensure the destination frame refers to the same data described by the source frame, either by creating a new reference for each AVBufferRef from src if they differ from those in dst, by allocating new buffers and copying data if src is not reference counted, or by unrefencing it if src is empty. 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 everything contained in src to dst and reset src. 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_props (AVFrame *dst, const AVFrame *src) |
Copy only "metadata" fields from src to dst. More... | |
AVBufferRef * | av_frame_get_plane_buffer (const AVFrame *frame, int plane) |
Get the buffer reference a given data plane is stored in. More... | |
AVFrameSideData * | av_frame_new_side_data_from_buf (AVFrame *frame, enum AVFrameSideDataType type, AVBufferRef *buf) |

static int | calc_cropping_offsets (size_t offsets[4], const AVFrame *frame, const AVPixFmtDescriptor *desc) |
int | av_frame_apply_cropping (AVFrame *frame, int flags) |
Crop the given video AVFrame according to its crop_left/crop_top/crop_right/ crop_bottom fields. More... | |
