Class Details¶

class GstVideo.VideoOrientation¶

Bases:: GObject.GInterface
Structure:: GstVideo.VideoOrientationInterface

The interface allows unified access to control flipping and autocenter operation of video-sources or operators.

classmethod from_tag(taglist)[source]¶

Parameters:

taglist (Gst.TagList) – A Gst.TagList

Returns:

True if there was a valid “image-orientation” tag in the taglist.

method:: The location where to return the orientation.

Return type:

(bool, method: GstVideo.VideoOrientationMethod)

Parses the “image-orientation” tag and transforms it into the GstVideo.VideoOrientationMethod enum.

New in version 1.20.

get_hcenter()[source]¶

Returns:

True in case the element supports centering

center:: return location for the result

Return type:

(bool, center: int)

Get the horizontal centering offset from the given object.

get_hflip()[source]¶

Returns:

True in case the element supports flipping

flip:: return location for the result

Return type:

(bool, flip: bool)

Get the horizontal flipping state (True for flipped) from the given object.

get_vcenter()[source]¶

Returns:

True in case the element supports centering

center:: return location for the result

Return type:

(bool, center: int)

Get the vertical centering offset from the given object.
