Fix delay used when polling for rendered buffers am: fce530c3

            // presentation timestamp is used instead, which almost certainly occurs in the past,

            // since it's almost always a zero-based offset from the start of the stream. In these

            // scenarios, we expect the frame to be rendered with no delay.

            int64_t delayUs = noRenderTime ? 0 : renderTimeNs / 1000 - ALooper::GetNowUs();

            delayUs += 100 * 1000; /* 100ms in microseconds */
