Looks to be an issue with getting the image. What is config of the "front" camera that you are using?

1.The parameters of my USB camera are as follows v4l2-ctl -d /dev/video0 --all Driver Info (not using libv4l2): Driver name : uvcvideo Card type : Rmoncam FHD 1080P: Rmoncam FHD Bus info : usb-0000:03:00.0-2 Driver version: 4.15.18 Capabilities : 0x84200001 Video Capture Streaming Extended Pix Format Device Capabilities Device Caps : 0x04200001 Video Capture Streaming Extended Pix Format Priority: 2 Video input : 0 (Camera 1: ok) Format Video Capture: Width/Height : 1920/1080 Pixel Format : 'MJPG' Field : None Bytes per Line : 0 Size Image : 4147200 Colorspace : sRGB Transfer Function : Default YCbCr Encoding : Default Quantization : Default Flags : Crop Capability Video Capture: Bounds : Left 0, Top 0, Width 1920, Height 1080 Default : Left 0, Top 0, Width 1920, Height 1080 Pixel Aspect: 1/1 Selection: crop_default, Left 0, Top 0, Width 1920, Height 1080 Selection: crop_bounds, Left 0, Top 0, Width 1920, Height 1080 Streaming Parameters Video Capture: Capabilities : timeperframe Frames per second: 30.000 (30/1) Read buffers : 0 brightness (int) : min=-64 max=64 step=1 default=0 value=0 contrast (int) : min=0 max=100 step=1 default=32 value=32 saturation (int) : min=0 max=100 step=1 default=64 value=64 hue (int) : min=-180 max=180 step=1 default=0 value=0 white_balance_temperature_auto (bool) : default=1 value=1 gamma (int) : min=100 max=500 step=1 default=300 value=300 gain (int) : min=1 max=128 step=1 default=64 value=64 power_line_frequency (menu) : min=0 max=2 default=1 value=1 white_balance_temperature (int) : min=2800 max=6500 step=10 default=4600 value=4600 flags=inactive sharpness (int) : min=0 max=100 step=1 default=50 value=50 backlight_compensation (int) : min=0 max=2 step=1 default=0 value=0 exposure_auto (menu) : min=0 max=3 default=3 value=3 exposure_absolute (int) : min=50 max=10000 step=1 default=166 value=166 flags=inactive exposure_auto_priority (bool) : default=0 value=1

2. I modified the "stream_setup.yaml" file as follows:

   Set up your streams to rtsp here.

   port: "8554" streams: # Cannot rename - must leave this as is.

   stream-x: type: cam source: "v4l2src device=/dev/video0 ! videoconvert ! videoscale ! video/x-raw,framerate=15/1,width=1920,height=1080" mountpoint: /front bitrate: 500

   stream-yay: type: topic source: /usb_cam1/image_raw mountpoint: /back caps: video/x-raw,framerate=10/1,width=640,height=480 bitrate: 500

Just throwing stuff out there, Maybe try adjusting the caps in stream_setup.yaml:

stream-x:
type: cam
source: "v4l2src device=/dev/video0 ! videoconvert ! videoscale ! video/x-raw,width=640,height=480"
mountpoint: /front
bitrate: 500

This shrinks the video resolution and doesn't specify the framerate. Also try with a framerate of 30/1 and 10/1. See if any of that makes a difference.

How did you go @yuqizhi ?

Closing this for now as original issue was resolved by installing the ugly plugins. Please open a new issue if you are still having trouble with your camera or let us know how you solved it!
