AMB82 Mini - USB-UVC 攝影機 for macOS

FreeRTOS USB
1

請問Ameba82 mini 的 free rtos sdk uvc example之後會打算支援macos?我在mac只有讀到相機，但vlc或內建facetime都沒有畫面。我在上面只找到目前只支援windows potplayer 或microsoft teams 、googlemeet 等平台

Hi @t112c53029 ,

請您在 component\example\media_uvcd\example_media_uvcd.h裡

把UVCD_MJPG 設成1, 其他的都設成0, 重新編譯再試試看

謝謝

3

那component\example\media_uvcd\example_media_uvcd.c 裡面的#define V1_TYPE

#define VIDEO_CODEC 需要修改嗎？

hi @t112c53029

不需要喔 這個不會影響UVC~

謝謝

hi @t112c53029 ,

請問您有修改sensor.h 的 USE_SENSOR 為 SENSOR_F37 嗎?

static const unsigned char sen_id[SENSOR_MAX] = {
	SENSOR_DUMMY,
	SENSOR_GC2053,
	SENSOR_GC4653,
	SENSOR_GC4023,
	SENSOR_F37
};

#define USE_SENSOR      	SENSOR_F37

static const      char manual_iq[SENSOR_MAX][64] = {
	"iq",
	"iq_gc2053",
	"iq_gc4653",
	"iq_gc4023",
	"iq_f37",
};

確認一下 USB-OTG 的線有插上對嗎

我有插上，sensor是對的相機有啟動，macbook facetime 讀得到 uvc class 但沒有畫面,但我windows的電腦內建相機程式讀得到相機且會有畫面
