MJPEG Cameras

The input and output parameters need to be adjusted for MJPEG cameras

input_args: -avoid_negative_ts make_zero -fflags nobuffer -flags low_delay -strict experimental -fflags +genpts+discardcorrupt -use_wallclock_as_timestamps 1

Note that mjpeg cameras require encoding the video into h264 for recording, and rtmp roles. This will use significantly more CPU than if the cameras supported h264 feeds directly.

output_args:
  record: -f segment -segment_time 10 -segment_format mp4 -reset_timestamps 1 -strftime 1 -c:v libx264 -an
  rtmp: -c:v libx264 -an -f flv

JPEG Stream Cameras

Cameras using a live changing jpeg image will need input parameters as below

input_args:
- -r
- 5 # << enter FPS here
- -stream_loop
- -1
- -f
- image2
- -avoid_negative_ts
- make_zero
- -fflags
- nobuffer
- -flags
- low_delay
- -strict
- experimental
- -fflags
- +genpts+discardcorrupt
- -use_wallclock_as_timestamps
- 1

Outputting the stream will have the same args and caveats as per MJPEG Cameras

RTMP Cameras

The input parameters need to be adjusted for RTMP cameras

ffmpeg:
  input_args: -avoid_negative_ts make_zero -fflags nobuffer -flags low_delay -strict experimental -fflags +genpts+discardcorrupt -rw_timeout 5000000 -use_wallclock_as_timestamps 1 -f live_flv

Reolink 410/520 (possibly others)

According to this discussion, the http video streams seem to be the most reliable for Reolink.

cameras:
  reolink:
    ffmpeg:
      hwaccel_args:
      input_args:
        - -avoid_negative_ts
        - make_zero

      inputs:

          roles:
            - record
            - rtmp

          roles:

    detect:
      width: 640

Blue Iris RTSP Cameras

You will need to remove nobuffer flag for Blue Iris RTSP cameras

ffmpeg:
  input_args: -avoid_negative_ts make_zero -flags low_delay -strict experimental -fflags +genpts+discardcorrupt -rtsp_transport tcp -stimeout 5000000 -use_wallclock_as_timestamps 1

UDP Only Cameras

If your cameras do not support TCP connections for RTSP, you can use UDP.

ffmpeg:
  input_args: -avoid_negative_ts make_zero -fflags +genpts+discardcorrupt -rtsp_transport udp -stimeout 5000000 -use_wallclock_as_timestamps 1
