如何判斷特定裝置和 AR 工作階段是否具備影格緩衝區 (以及
稱為影格延遲)，使用 adb Logcat 輸出內容：
# Camera frame buffering is turned off when frame delay is zero.adblogcat|grep'Update Frame Delay'…Inative:session.cc:3141UpdateFrameDelayto0frames.
# Camera frame buffering is turned on when frame count is non-zero.# Note: The size of the buffer can vary over time.adblogcat|grep'Update Frame Delay'…Inative:session.cc:3141UpdateFrameDelayto6frames.……Inative:session.cc:3141UpdateFrameDelayto4frames.……Inative:session.cc:3141UpdateFrameDelayto2frames.
記憶體
每增加一個相機影格，就會提高記憶體使用率。例如：
1080p 紋理會消耗約 6 MB 的記憶體 (只要將
解析度為 1920 x 1080 x 3 位元組 RGB 資料。
