3 // Android system might want to allocate some color buffers with formats
4 // that are not compatible with most OpenGL implementations,
5 // such as YV12.
6 // In this situation, we need to convert to some OpenGL format such as
7 // RGB888 that actually works.
8 // While we can do some of this conversion in the guest gralloc driver itself
9 // (which would make ColorBuffer see only the OpenGL formatted pixels),
10 // it may be advantageous to do the conversion on the host as well.
11 // FrameworkFormat tracks whether the incoming color buffer from the guest
12 // can be directly used as a GL texture (FRAMEWORK_FORMAT_GL_COMPATIBLE).
13 // Otherwise, we need to know which format it is (e.g., FRAMEWORK_FORMAT_YV12)
14 // and convert on the host.
