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, qsv_decode.c, qsv_transcode.c, vaapi_encode.c, and vaapi_transcode.c.

Definition at line 82 of file buffer.h.

Field Documentation

◆ buffer

AVBuffer* AVBufferRef::buffer

◆ data

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
vaapi_encode.c.

Definition at line 90 of file buffer.h.
