5 // The bulk of this file is support code; sorry about that. Here's an overview
6 // to hopefully help readers of this code:
7 // - RenderingHelper is charged with interacting with X11/{EGL/GLES2,GLX/GL} or
9 // - ClientState is an enum for the state of the decode client used by the test.
10 // - ClientStateNotification is a barrier abstraction that allows the test code
11 // to be written sequentially and wait for the decode client to see certain
13 // - GLRenderingVDAClient is a VideoDecodeAccelerator::Client implementation
14 // - Finally actual TEST cases are at the bottom of this file, using the above
19 #include <sys/types.h>
24 // Include gtest.h out of order because <X11/X.h> #define's Bool & None, which
25 // gtest uses as struct names (inside a namespace). This means that
26 // #include'ing gtest after anything that pulls in X.h fails to compile.
