GstVideoBufferPool

Special GstBufferPool subclass for raw video buffers.

Allows configuration of video-specific requirements such as stride alignments or pixel padding, and can also be configured to automatically add GstVideoMeta to the buffers.

Constants

GST_BUFFER_POOL_OPTION_VIDEO_ALIGNMENT 

#define GST_BUFFER_POOL_OPTION_VIDEO_ALIGNMENT "GstBufferPoolOptionVideoAlignment"

A bufferpool option to enable extra padding. When a bufferpool supports this option, gst_buffer_pool_config_set_video_alignment can be called.

When this option is enabled on the bufferpool, GST_BUFFER_POOL_OPTION_VIDEO_META should also be enabled.

GstVideo.BUFFER_POOL_OPTION_VIDEO_ALIGNMENT

A bufferpool option to enable extra padding. When a bufferpool supports this option, GstVideo.prototype.buffer_pool_config_set_video_alignment can be called.

When this option is enabled on the bufferpool, GstVideo.BUFFER_POOL_OPTION_VIDEO_META should also be enabled.

GstVideo.BUFFER_POOL_OPTION_VIDEO_ALIGNMENT

A bufferpool option to enable extra padding. When a bufferpool supports this option, GstVideo.buffer_pool_config_set_video_alignment can be called.

When this option is enabled on the bufferpool, GstVideo.BUFFER_POOL_OPTION_VIDEO_META should also be enabled.

GST_BUFFER_POOL_OPTION_VIDEO_META 

#define GST_BUFFER_POOL_OPTION_VIDEO_META "GstBufferPoolOptionVideoMeta"

An option that can be activated on bufferpool to request video metadata on buffers from the pool.

GstVideo.BUFFER_POOL_OPTION_VIDEO_META

An option that can be activated on bufferpool to request video metadata on buffers from the pool.

GstVideo.BUFFER_POOL_OPTION_VIDEO_META

An option that can be activated on bufferpool to request video metadata on buffers from the pool.
