[Motion-user] RTSP problem on Raspberry Pi 3 with both motion 4.2.2 and latest github master versions
|

I experienced a problem similar to issue #986 with motion 4.2.2 and RTSP
cameras ("could not fetch initial image from camera"). I am using
raspbian 9.9 (up-to-date) with a motion 4.2.2 rebuilt from sources. I
decided to clone the github repository, built motion from master and
restarted it. Now motion tells me that the cameras are active (but no
image), and then change to "Lost connection" after a short delay.
The reason why motion fails the video stream might be a timeout (see
below). If I want to tinker with the motion's timeout, where should I look?
The two cameras are the Alptop AT-200B model. I can access each camera
through VLC using the same rstp URL, and the image shows up quickly.
When using ffplay, the output is as follow:
$ ffplay -rtsp_transport tcp rtsp://motion:H9B1Dm@192.168.0.211/stream1

It stays like this for /3//minutes/, then a windows opens that displays
the image, with these additional output on the console:
[rtsp @ 0x68300490] Stream #0: not enough frames to estimate rate;

This is a low resolution stream (640x480). It seems that the camera
takes time to send data, or ffmpeg is confused by the first frames (but
not VLC?).
(As a side note, I have the cameras on an isolated network only
accessible from the RPI3, so VLC and ffplay run on the RPI3 through a
ssh -X tunnel from my workstation.)

I upgraded raspbian to buster, and rebuilt the latest motion with the
new buster libraries: same behavior from both vlc (OK), ffplay (a few
minutes delay) and motion (lost connection after a short while). The log
from motion is then:
