Functions | |
static void | get_frame_defaults (AVFrame *frame) |
static void | free_side_data (AVFrameSideData **ptr_sd) |
static void | wipe_side_data (AVFrameSideData ***sd, int *nb_side_data) |
static void | frame_side_data_wipe (AVFrame *frame) |
void | av_frame_side_data_free (AVFrameSideData ***sd, int *nb_sd) |
Free all side data entries and their contents, then zeroes out the values which the pointers are pointing to. More... | |
static void | remove_side_data (AVFrameSideData ***sd, int *nb_side_data, const enum AVFrameSideDataType type) |
static void | remove_side_data_by_entry (AVFrameSideData ***sd, int *nb_sd, const AVFrameSideData *target) |
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) |

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) |

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... | |
