#pragma once // Android system might want to allocate some color buffers with formats // that are not compatible with most OpenGL implementations, // such as YV12. // In this situation, we need to convert to some OpenGL format such as // RGB888 that actually works. // While we can do some of this conversion in the guest gralloc driver itself // (which would make ColorBuffer see only the OpenGL formatted pixels), // it may be advantageous to do the conversion on the host as well. // FrameworkFormat tracks whether the incoming color buffer from the guest // can be directly used as a GL texture (FRAMEWORK_FORMAT_GL_COMPATIBLE). // Otherwise, we need to know which format it is (e.g., FRAMEWORK_FORMAT_YV12) // and convert on the host. enum FrameworkFormat { FRAMEWORK_FORMAT_GL_COMPATIBLE = 0, FRAMEWORK_FORMAT_YV12 = 1, FRAMEWORK_FORMAT_YUV_420_888 = 2, };
