Detailed Description

A reference to a data buffer.

The size of this struct is not a part of the public ABI and it is not meant to be allocated directly.

Examples:: hw_decode.c, qsvdec.c, vaapi_encode.c, and vaapi_transcode.c.

Definition at line 81 of file buffer.h.

Definition at line 82 of file buffer.h.

Referenced by av_buffer_create(), av_buffer_get_opaque(), av_buffer_get_ref_count(), av_buffer_is_writable(), av_buffer_realloc(), av_buffer_ref(), h264_initialise_ref_list(), h264_slice_init(), pool_alloc_buffer(), and try_push_frame().

uint8_t* AVBufferRef::data

The data buffer.

It is considered writable if and only if this is the only reference to the buffer, in which case av_buffer_is_writable() returns 1.

Examples:: qsvdec.c, and vaapi_encode.c.
