    摘要: Converting a first format frame to one or more second format frames. In one embodiment, a method includes accessing a first format frame using n coefficients, where n is the total number of coefficients used for the Y, U and V planes of the first format frame. The method further includes mapping the coefficients of the first format frame to coefficients of one or more second format frames. The one or more second format frames have n coefficients across all of the second format frames matching the n coefficients of the first format frame.

    摘要: Video frames of a higher-resolution chroma sampling format such as YUV 4:4:4 are packed into video frames of a lower-resolution chroma sampling format such as YUV 4:2:0 for purposes of video encoding. For example, sample values for a frame in YUV 4:4:4 format are packed into two frames in YUV 4:2:0 format. After decoding, the video frames of the lower-resolution chroma sampling format can be unpacked to reconstruct the video frames of the higher-resolution chroma sampling format. In this way, available encoders and decoders operating at the lower-resolution chroma sampling format can be used, while still retaining higher resolution chroma information. In example implementations, frames in YUV 4:4:4 format are packed into frames in YUV 4:2:0 format such that geometric correspondence is maintained between Y, U and V components for the frames in YUV 4:2:0 format.
