Universal color-space inverse transform coding
In general, this disclosure describes techniques for coding video blocks using a color-space conversion process. A video coder, such as a video encoder or a video decoder, may determine a coding mode used to encode the video data. The coding mode may be one of a lossy coding mode or a lossless coding mode. The video coder may determine a color-space transform process dependent on the coding mode used to encode the video data. The video coder may apply the color-space transform process in encoding the video data. In decoding the video data, independent of whether the coding mode is the lossy coding mode or the lossless coding mode, the video coder may apply the same color-space inverse transform process in a decoding loop of the encoding process.
