// 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.
