                这个demo没有跑过, 但是从这上面的显示信息来看, 这个demo每次输出长度都不一样, 你的每次长度都一样, 我怀疑你的摄像头默认是输出YUV/RGB格式数据。

                一会我找个软件给你显示。

                    试一试这个软件: b3940e06-788d-487d-a2db-2ecde4b3a06e-YUView-Win.zip

                    填好分辨率, 把格式那里都试一试。

                        @karrena 打开文件的时候第一个窗口选RGB/YUV之后就有了
