Data Structures | |
| struct | AVFrameSideData |
| Structure to hold side data for an AVFrame. More... | |
| struct | AVRegionOfInterest |
| Structure describing a single Region Of Interest. More... | |
| struct | AVFrame |
| This structure describes decoded (raw) audio or video data. More... | |
Macros | |
| #define | AV_NUM_DATA_POINTERS 8 |
| #define | AV_FRAME_FLAG_CORRUPT (1 << 0) |
| The frame data may be corrupted, e.g. More... | |
| #define | AV_FRAME_FLAG_KEY (1 << 1) |
| A flag to mark frames that are keyframes. More... | |
| #define | AV_FRAME_FLAG_DISCARD (1 << 2) |
| A flag to mark the frames which need to be decoded, but shouldn't be output. More... | |
| #define | AV_FRAME_FLAG_INTERLACED (1 << 3) |
| A flag to mark frames whose content is interlaced. More... | |
| #define | AV_FRAME_FLAG_TOP_FIELD_FIRST (1 << 4) |

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... | |
| 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_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) |

| Add a new side data to a frame. More... | |
| AVFrameSideData * | av_frame_new_side_data_from_buf (AVFrame *frame, enum AVFrameSideDataType type, AVBufferRef *buf) |
| Add a new side data to a frame from an existing AVBufferRef. More... | |
| AVFrameSideData * | av_frame_get_side_data (const AVFrame *frame, enum AVFrameSideDataType type) |
| void | av_frame_remove_side_data (AVFrame *frame, enum AVFrameSideDataType type) |
| Remove and free all side data instances of the given type. More... | |
| 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... | |
| const char * | av_frame_side_data_name (enum AVFrameSideDataType type) |
