Args: width (int): Initial width of the video source. height (int): Initial height of the video source. is_screencast (bool, optional): Optimize the WebRTC pipeline for screen content. Defaults to False. When True, WebRTC will: - Maintain resolution under congestion by dropping frames instead of downscaling (keeps text crisp) - Disable quality scaling and denoising to preserve text/UI readability - Guarantee a minimum 1200 kbps bitrate floor - Enable zero-hertz mode, stopping frame transmission when the screen is static to save bandwidth - Set content type to screen, adjusting encoder configuration throughout the pipeline (VP9 inter-layer prediction, simulcast layer allocation, etc.) N) proto_ffi FfiRequest proto_videoVideoSourceTypeVIDEO_SOURCE_NATIVEnew_video_sourcetype resolutionr r r rinstancerequestsource_inforhandleid _ffi_handle)selfr r r reqrespr#Z/var/www/html/livekit_bhavya/venv/lib/python3.10/site-packages/livekit/rtc/video_source.py__init__s     zVideoSource.__init__r) timestamp_usrotationframerr&r'#proto_video.VideoRotation.ValueTypecCsFt}|jj|j_|jj|||j_ ||j_ t j |dSN)rrrrcapture_video_frame source_handlebufferCopyFrom _proto_infor'r&rrr)r r(r&r'r!r#r#r$ capture_frame7s  zVideoSource.capture_framecs|jdSr*)rdispose)r r#r#r$acloseEszVideoSource.acloseN)r r r r r rrr)r(rr&r r'r)rr)rr) __name__ __module__ __qualname__r%r VideoRotationVIDEO_ROTATION_0r0r2r#r#r#r$r s #r N) __future__r _ffi_clientrr_protorrrr video_framerr r#r#r#r$s
