Detailed Description

Bitmap information.

This metadata contains a bitmap image in the given format and size. It is typically used for cursor images or other small images that are better transferred inline.

Examples

video-play-pull.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.

Field Documentation

format

uint32_t spa_meta_bitmap::format

bitmap video format, one of enum spa_video_format.

0 is and invalid format and should be handled as if there is no new bitmap information.

Examples

video-play-pull.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.

size

struct spa_rectangle spa_meta_bitmap::size

width and height of bitmap

Examples

video-play-pull.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.

stride

int32_t spa_meta_bitmap::stride

stride of bitmap data

Examples

video-play-pull.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.

offset

uint32_t spa_meta_bitmap::offset

offset of bitmap data in this structure.

An offset of 0 means no image data (invisible), an offset >= sizeof(struct spa_meta_bitmap) contains valid bitmap info.

Examples

video-play-pull.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.
