GStreamer team,

I am capturing video using a BlackMagic Video device, sending out using a VP9 encoder, and then using a payloader for use with webRTC. When I view the stream, my blacks and whites are mapped 16-235 instead of 0-255. Is there a way to correct this? WIth ffmpeg, I can use a filter graph and and set the input and output scale “scale=in_range=limited:out_range=limited”.
