      @veye_xumm 好的,我再觀察比較ㄧ下不同環境跟不同攝像頭看看。

      @veye_xumm 可以重啟。但我在日光燈下還是有條紋。x_2.jpg

      @veye_xumm 另一個想法,如果仿照這作法,camera 收到 USB 0x5514 做 reset (reboot) 可行嗎?

      @veye_xumm 那是否也能把 power_line_frequency 也放進去支援 60hz ? 或是如果是特製版,那能直接把預設做成 60hz 嗎?

      @veye_xumm 我的意思是,就目前的版本,我也無法去設定他的值(但在其他的攝像頭可以設定)。所以是否改的冒用的版本也不能用?

      @coolmitch 我用另一個別的廠牌的 uvc camera 可以這樣設定。

      @veye_xumm
      色度是指這個嗎?我可以試看看
      hue 0x00980903 (int) : min=0 max=100 step=1 default=50 value=50
      我用 v4l2-ctl 下
      v4l2-ctl -d /dev/video0 --set-ctrl=hue=0
      可是它還是顯示 value=50

      @veye_xumm 這篇我有看過,當時看它是對 usb hub 下命令,所以我就沒去試了。其實我的機器不是開發板,是用 nvidia computer module 做的機器。我也會問看看主機板供應商有沒有辦法(之前問過是說不行)。還要再麻煩你幫我看看有沒有辦法不斷電讓它連續運行(雖然目前有大幅度進步,但仍然久了還是會斷線)或是說有什麼 uvc 的命令可以讓它自動 reset 重啟我這邊也可以配合來下相對應的命令。
