Here is how to patch ffmpeg and force camera to TCP to workaround a non-compliant RTSP camera Related: https://github.com/Motion-Project/motion/issues/1071, https://sourceforge.net/p/motion/mailman/message/58717607/

  1. Get ffmpeg sources: git clone https://github.com/ffmpeg/ffmpeg
  2. cd ffmpeg
  3. Pull the patch: wget https://raw.githubusercontent.com/eusoubrasileiro/motion_server_nvr/jetson-nano/ansible/roles/jnano/files/RTSP_lower_transport_TCP.patch
  4. Apply patch: git apply < RTSP_lower_transport_TCP.patch
  5. Install ffmpeg dependencies: sudo apt-get install yasm lib264-dev
  6. ./configure --prefix=/full/path/to/ffmpeg/out --enable-gpl --enable-libx264
  7. make -j4
  8. make install
  9. cd ..
  10. Get motion sources: git clone https://github.com/Motion-Project/motion
  11. cd motion
  12. Install build dependencies: sudo apt-get -y install autoconf automake build-essential pkgconf libtool libzip-dev libjpeg-dev libwebp-dev libmicrohttpd-dev autopoint
  13. Remove ffmpeg system libs: sudo apt-get remove libavformat-dev libavcodec-dev libavutil-dev libswscale-dev libavdevice-dev
  14. autoreconf -fiv
  15. ./configure --with-ffmpeg=/full/path/to/ffmpeg/out
  16. make
  17. Test: ./src/motion -c your_config.conf -d 9 -n

Nice. Whats the downsize of doing it this way? It seems like out of the box, motion does not support h.264 codec.

tosiara commented 8 months ago

Packaged Motion uses ffmpeg libs to decode H264 and it comes out of the box. It's only a problem with some non-compliant cameras that require a custom ffmpeg build with a workaround to force TCP

bytes-commerce commented 8 months ago

After writing the comment, I figured that mkv for example is h264 encoded, so that worked. Sorry for the irrelevant weight to the issue.

Mr-Dave commented 8 months ago

Can you explain this issue more? Generally, we don't want UDP we want rtsp_transport tcp and this can be specified via the Motion option of netcam_params. (It is actually already the default). I didn't think that any such patch to ffmpeg was required. Simply specify it as the option instead of UDP.

For general issues with the camera not being detected or failing to analyze, the solution is usually to lower the camera GOP/I-Frame interval.

tosiara commented 8 months ago

The issue here is that ffmpeg out of the box tries to follow RTSP protocol. The camera in turn, supports TCP, but does not advertise it correctly, and motion fails to connect since motion forces TCP by default (perfectly explained by @eusoubrasileiro at https://stackoverflow.com/questions/66280861/ffmpeg-nonmatching-transport-in-server-reply-but-openrtsp-works)

There are two workarounds here.

  1. Configure motion to use UDP
  2. Or, patch ffmpeg to force use TCP even though the camera does follow RTSP protocol standards
Mr-Dave commented 8 months ago

I'm still not following the issue/problem for Motion to resolve. Is this just a FYI/"How to" for those that have one of these cameras?

tosiara commented 8 months ago

Yes, this was more like FYI for everyone as there were many users affected
