      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。

          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。
