Hi!
i have a few RTSP cameras, they are crappy Chinese v380 ones, and quite
slow in responding, but nontheless, they work.
I have intermittent images from the cameras, and i get a lot of messages
like this:
[11:ml11] [ERR] [VID] vid_start: Netcam RTSP failed to open
[11:ml11] [WRN] [ALL] motion_init: Could not fetch initial image from
camera
[11:ml11] [WRN] [ALL] motion_init: Motion continues using width and
height from config file(s)
[11:ml11] [WRN] [ALL] mlp_retry: Retrying until successful connection
with camera
[11:ml11] [ERR] [NET] netcam_rtsp_open_context: Normal resolution:
Unable to open camera((null)): Connection refused
[11:ml11] [ERR] [VID] vid_start: Netcam RTSP failed to open
After a while the image resume correctly. The RTSP camera output x264
compressed stream and i can _always_ get a frame using ffpmeg directly,
albeit it's quite slow (can take from 1 to 2 or 3 secs to get an image
manually).
Somebody has ideas on how to debug or improve this?

What works for me with my software (https://github.com/flok99/constatus
) is setting the i-frame interval to 1. Thus every frame transmitted by
the camera is in i-frame.
I realised that for me also the first frame is always correct, and the
first frame is always an i-frame. So there you are.

Is this something you do on the camera or on motion?
