GstVideoMeta

Extra buffer metadata describing image properties

This meta can also be used by downstream elements to specifiy their buffer layout requirements for upstream. Upstream should try to fit those requirements, if possible, in order to prevent buffer copies.

This is done by passing a custom GstStructure to gst_query_add_allocation_meta when handling the ALLOCATION query. This structure should be named 'video-meta' and can have the following fields:

  • padding-top (uint): extra pixels on the top
  • padding-bottom (uint): extra pixels on the bottom
  • padding-left (uint): extra pixels on the left side
  • padding-right (uint): extra pixels on the right side The padding fields have the same semantic as alignment and so represent the paddings requested on produced video buffers.

the paddings and alignment constraints of the video buffer. It is up to the caller of gst_buffer_add_video_meta_full() to set it using gst_video_meta_set_alignment, if they did not it defaults to no padding and no alignment. Since: 1.18
