Previously it was described as MediaTek block mode, and now as a MediaTek compressed format. It makes me think you have no idea what this pixel format really is. Is that right ? The main reason why I keep asking, is that we often find similarities between what vendor like to call their proprietary formats. Doing the proper research helps not creating a mess like in Android where you have a lot of formats that all point to the same format. I believe there was the same concern when Samsung wanted to introduce their Z- flip-Z NV12 tile format. In the end they simply provided sufficient documentation so we could document it and implement software converters for test and validation purpose. regards, Nicolas -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
