      抓拍过程是 214帧开始采集5秒，同时立即开始闪光 5秒内可采集约1075张 用上面的参数测试
      下面是抓拍到一帧时(大部分抓不到) 但亮度比较强看不到渐变过程。

        已电话沟通，建议通过调节roi来提高帧率。

          改成640x512 取图 能抓到了 87ff36b9-987b-4f93-a81a-2e7eb455a1d1-图片.png

          这个是用自动曝光 可以抓到 第一张和第三张 这种需要的 。曝光不知道还有没有可调整的空间

            你这种应用模式，需要改成手动曝光。
            具体用多大的曝光时间，需要你去实际测试一下。
            https://wiki.veye.cc/index.php/Mv_mipi_i2c.sh_user_guide

            expmode 设置为0
            gainmode 设置为0
            metime 调节曝光时间
            mgain 调节增益

              曝光时间单位是 微秒吗

                  @veye_xumm 用gst采集一段视频效果 帧率为什么不是200多帧

                    @xhamigua 编码效率的问题啊，缓存的问题啊，很多因素。

                      @veye_xumm 有没有 全帧率缓存的方法 存下录制视频

                        @xhamigua 如果你抓的时间不长的话，建议你写程序，把raw数据全部缓存到内存里面，然后再慢慢编码。

                          @veye_xumm 是的 非阻塞缓存后写图，已经解决了。抓拍的图像基本模拟一次就有一张抓拍，因为闪一次时间是1ms 所以只抓到一张也是合理的。
