Summary0000175: When encoding single 1080p frame, 10bits chroma and luma, 4:2:2 both chroma components are set to zero
DescriptionEncoding a single 1920x1080 frame with a bit-depth of 10 for both luma and chroma, in planar 4:2:2 the encoder seems to always report SNR of 60.2 for both chroma channels, and the decoded output appears to have both chrominance channels set to a hard 0 (ie. Green) on every pixel.
