Detailed Description

Data structure for storing block-level encoding information.

It is allocated as a part of AVVideoEncParams and should be retrieved with av_video_enc_params_block().

sizeof(AVVideoBlockParams) is not a part of the ABI and new fields may be added to it.

Field Documentation

src_x

int AVVideoBlockParams::src_x

Distance in luma pixels from the top-left corner of the visible frame to the top-left corner of the block.

Can be negative if top/right padding is present on the coded frame.
