[BUG] RTSP stream not starting on RPi 5

[GitHubGoody]

Describe the bug
I have an RPi 5 8GB running headless on the latest Raspberry Pi OS available via the RPi Imager with an RPi Camera Module 3 Wide connected. I'm simply trying to get it configured to stream RTSP but I keep getting errors and the stream does not start.

Bug report
I attached the bug report generated using this command:
camera-bug-report -t <timeout in seconds> -o <output file> -c "<rpicam-vid -t 0 --inline -o - | cvlc stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/stream}' :demux=h264>

This is the issue I posted on the forum here:

I have an RPi 5 8GB running headless on the latest Raspberry Pi OS available via the RPi Imager with an RPi Camera Module 3 Wide connected. I'm simply trying to get it configured to stream RTSP.

After running all of these commands to update it...

sudo apt update
supo apt upgrade
sudo apt install vlc
sudo apt install ffmpeg

...I tried the instructions offered here: https://www.raspberrypi.com/documentation/computers/camera_software.html#rtsp

When I try...
rpicam-hello
...it starts the stream

When I try...
rpicam-jpeg --output test.jpg
...it streams for 5 seconds and outputs a test.jpg image that I can retrieve via WinSCP and it looks great.

When I try...
rpicam-vid -t 10s -o test.mp4
...it streams for 10 seconds and outputs a test.mpg video that I can retrieve via WinSCP at it looks great.

When I try to start a stream with this...
rpicam-vid -t 0 --inline -o - | cvlc stream:///dev/stdin --sout '#rtp{sdp=rtsp://:8554/stream}' :demux=h264
...I get this result and errors...

Can you try adding --libav-format h264 into the command line?
