        你好,不好意思,现在我们的USB型号对标注UVC的参数支持的不完善。

          @veye_xumm 我發現有在日光燈底下會發生橫紋的問題,應該是交流電頻率 50hz/60hz 造成的影像。若 uvc 參數支持度不完善,請問我有辦法設定 power_line_frequency 為 60hz 嗎?

            这个参数是支持的。下面这个截图,是我采用pc端 potplayer对应的参数调整的位置。

            下面这个截图是amcap对应的配参数的地方。

              @veye_xumm 請問這個是設定一次就好,還是每次開機後都要設定?有沒有 linux 的指令?

                每次都要设定一下。 对应的linux下指令,暂时还提供不了给你。
