struct AVFrame

Defined at line 330 of file ../../prebuilt/third_party/ffmpeg/pkg/ffmpeg/include/libavutil/frame.h

This structure describes decoded (raw) audio or video data.

AVFrame must be allocated using av_frame_alloc(). Note that this only

allocates the AVFrame itself, the buffers for the data must be managed

through other means (see below).

AVFrame must be freed with av_frame_free().

AVFrame is typically allocated once and then reused multiple times to hold

different data (e.g. a single AVFrame to hold frames received from a

decoder). In such a case, av_frame_unref() will free any references held by

the frame and reset it to its original clean state before it

is reused again.

The data described by an AVFrame is usually reference counted through the

AVBuffer API. The underlying buffer references are stored in AVFrame.buf /

AVFrame.extended_buf. An AVFrame is considered to be reference counted if at

least one reference is set, i.e. if AVFrame.buf[0] != NULL. In such a case,

every single data plane must be contained in one of the buffers in

AVFrame.buf or AVFrame.extended_buf.

There may be a single buffer for all the data, or one separate buffer for

each plane, or anything in between.

sizeof(AVFrame) is not a part of the public ABI, so new fields may be added

to the end with a minor bump.

Fields can be accessed through AVOptions, the name string used, matches the

C structure field name for fields accessible through AVOptions. The AVClass

for AVFrame can be obtained from avcodec_get_frame_class()
