    Abstract: An example method of decoding video data includes receiving a plurality of pictures, receiving, in a message associated with a first picture of the plurality of pictures, information indicating a picture order count (POC) value of a recovery point picture of a gradual decoder refresh (GDR) set, when a picture that follows the first picture in decoding order has the POC value that is equal to a POC value of the recovery point picture, identifying the picture having the POC value equal to the POC value of the recovery point picture, as a recovery point picture, and when none of the pictures that follow the first picture has the POC value that is equal to the POC value of the recovery point picture, identifying one of the pictures that has a POC value greater than the POC value of the recovery point picture as the recovery point picture.

    Abstract: This disclosure relates to processing video data, including processing video data to conform to a high dynamic range (HDR)/wide color gamut (WCG) color container. The techniques apply, on an encoding side, pre-processing of color values prior to application of a static transfer function and/or apply post-processing on the output from the application of the static transfer function. By applying pre-processing, the examples may generate color values that when compacted into a different dynamic range by application of the static transfer function linearize the output codewords. By applying post-processing, the examples may increase signal to quantization noise ratio. The examples may apply the inverse of the operations on the encoding side on the decoding side to reconstruct the color values.

    Abstract: A device may determine, based on data in a bitstream, a luma sample (Y) of a pixel, a Cb sample of the pixel, and the Cr sample of the pixel. Furthermore, the device may obtain, from the bitstream, a first scaling factor and a second scaling factor. Additionally, the device may determine, based on the first scaling factor, the Cb sample for the pixel, and Y, a converted B sample (B′) for the pixel. The device may determine, based on the second scaling factor, the Cr sample for the pixel, and Y, a converted R sample (R′) for the pixel. The device may apply an electro-optical transfer function (EOTF) to convert Y′, R′, and B′ to a luminance sample for the pixel, a R sample for the pixel, and a B sample for the pixel, respectively.
