Class Details¶

class GstCodecs.H266Decoder(**kwargs)¶

Bases:: GstVideo.VideoDecoder
Abstract:: Yes
Structure:: GstCodecs.H266DecoderClass

The opaque GstCodecs.H266Decoder data structure.

New in version 1.26.

do_decode_slice(picture, slice) virtual¶

Parameters:

picture (GstCodecs.H266Picture) – a GstCodecs.H266Picture
slice (GstCodecs.H266Slice) – a GstCodecs.H266Slice

Return type:

Gst.FlowReturn

Provides per slice data with parsed slice header and required raw bitstream for subclass to decode it.

New in version 1.26.

do_end_picture(picture) virtual¶

Parameters:: picture (GstCodecs.H266Picture) – a GstCodecs.H266Picture
Return type:: Gst.FlowReturn

Optional. Called per one GstCodecs.H266Picture to notify subclass to finish decoding process for the GstCodecs.H266Picture

New in version 1.26.

do_get_preferred_output_delay(live) virtual¶

Parameters:: live (bool) – whether upstream is live or not
Returns:: the number of perferred delayed output frame
Return type:: int

Optional. Called by baseclass to query whether delaying output is preferred by subclass or not.

New in version 1.26.

do_new_picture(frame, picture) virtual¶

Parameters:

frame (GstVideo.VideoCodecFrame) – a GstVideo.VideoCodecFrame
picture (GstCodecs.H266Picture) – a GstCodecs.H266Picture

Return type:

Gst.FlowReturn

Optional. Called whenever new GstCodecs.H266Picture is created. Subclass can set implementation specific user data on the GstCodecs.H266Picture via gst_h266_picture_set_user_data

New in version 1.26.

do_output_picture(frame, picture) virtual¶

Parameters:

frame (GstVideo.VideoCodecFrame) –
picture (GstCodecs.H266Picture) –

Return type:

Gst.FlowReturn

do_start_picture(picture, slice, dpb) virtual¶

Parameters:

picture (GstCodecs.H266Picture) – a GstCodecs.H266Picture
slice (GstCodecs.H266Slice) – a GstCodecs.H266Slice
dpb (GstCodecs.H266Dpb) – a GstCodecs.H266Dpb

Return type:

Gst.FlowReturn

Optional. Called per one GstCodecs.H266Picture to notify subclass to prepare decoding process for the GstCodecs.H266Picture

New in version 1.26.
