viseron Jetson Nano rtsp: ffmpeg "Cannot assign requested address"

tldr; ffmpeg version n4.2.2-15-g6878ea5a44 contains this bug which means it dies with rtsp streams if -timeout is used. Viseron uses -timeout :-)

If you Google this you will find advice to replace -timeout <seconds> with -stimeout <microseconds>, which works up until 5.x when the ffmpeg devs decided to rename -timeout to -listen_timeout, and -stimeout to -timeout.

option 1: Upgrade to ffmpeg 5.x option 2: Replace the use of -timeout 5000000 with -stimeout 5000000, worry about ffmpeg 5 later.

Note that -timeout is measured in seconds, so, if it worked, the timeout would be 58 days :-)

Here are some logs:

Also, an explanation of the 'timeout' renaming saga.

I have a work-around. Add the following to the ffmpeg config for your camera:

ffmpeg:
  camera:
    camera_1:
      name: DrivewayCam
...
      input_args:
              - "-timeout"
              - "0"
              - "-stimeout"
              - "5000000"

It's been a tonne of work, and I've learned a lot. Now it's time to try out Viseron and see if I like -- I sure hope so!

Finally, I just noticed here, that "The Jetson Nano support is very limited in FFmpeg. If you have a Nano i suggest looking at the gstreamer component instead."

Ooops.
