Bug 1902115 and Bug 1904471 will implement a YUV-to-RGB data format and color conversion, respectively. However, the conversions are done individually. These two conversions could probably be optimized by the

  1. Replacing a two-step conversion with a one-pass conversion that can directly convert the YUV data into the required RGB format within specified color space.
  2. Using GPU to accelerate the process
  3. Using multiple threads for each R, G, B, and A channels to speed the process
