Class Details

class GstVideo.VideoFilter(**kwargs)

Bases:

GstBase.BaseTransform

Abstract:

Yes

Structure:

GstVideo.VideoFilterClass

Provides useful functions and a base class for video filters.

The videofilter will by default enable QoS on the parent GstBase.BaseTransform to implement frame dropping.

do_set_info(incaps, in_info, outcaps, out_info) virtual

Parameters:

• incaps (Gst.Caps) –

• in_info (GstVideo.VideoInfo) –

• outcaps (Gst.Caps) –

• out_info (GstVideo.VideoInfo) –

Return type:

bool

function to be called with the negotiated caps and video infos

do_transform_frame(inframe, outframe) virtual

Parameters:

• inframe (GstVideo.VideoFrame) –

• outframe (GstVideo.VideoFrame) –

Return type:

Gst.FlowReturn

transform a video frame

do_transform_frame_ip(frame) virtual

Parameters:

frame (GstVideo.VideoFrame) –

Return type:

Gst.FlowReturn

transform a video frame in place
