UVC example gets wrong aspect ratio, always 1:1 (AEGHB-892) #434

General issue report

I encountered a proportion problem when using the usb_camera_mic_spk example. As shown in picture 1, the rightmost side of each captured frame seems to be in a torn state, and the actual effective aspect ratio is 1:1, and the width is Extrusion, no matter I use 320x240 or 640x480, the actual effective display part is 240x240 or 480x480. What is the problem? I only modified ENABLE_UVC_FRAME_RESOLUTION_ANY=0 DEMO_UVC_FRAME_WIDTH=320 DEMO_UVC_FRAME_HEIGHT=240 can anyone help me? error1 error2 error3 error4

@suiyi1420 The USB driver doesn't change the image, including the aspect ratio. It just fetches and then outputs the image as it is.

Please attach your log file to further find out the cause.

When I use VLC Player to connect the camera, the image ratio I get is correct. Is there a way to get the computer to run the camera as USB1.1? In order to verify that it is a device problem? The following is the log of ESP-IDF: ESP-IDF: V5.1.5 MCU: ESP32-S3
