Motion - can't get streaming working from a webcam
- by Emmanuel Brunet
I'm trying to record a video stream from my Tenvis IP camera with motion 3.2.12 on Debian 7.5.
I used the standard debian package with
sudo apt-get install motion
Assume my DNS IP cam is webcam, user : admin, password : password
/etc/motion/motion.conf
Bellow are my configuration file settings :
netcam_url http://webcam/videostream.cgi
netcam_userpass admin:password
target_dir /media/videos/log/motion
# The mini-http server listens to this port for requests (default: 0 = disabled)
webcam_port 1234
ffmpeg_cap_new on
ffmpeg_video_codec mpeg4
output_motion off
snapshot_interval 0
# Quality of the jpeg (in percent) images produced (default: 50)
webcam_quality 50
# Output frames at 1 fps when no motion is detected and increase to the
# rate given by webcam_maxrate when motion is detected (default: off)
webcam_motion on
# Maximum framerate for webcam streams (default: 1)
webcam_maxrate 15
# Restrict webcam connections to localhost only (default: on)
webcam_localhost on
# Limits the number of images per connection (default: 0 = unlimited)
# Number can be defined by multiplying actual webcam rate by desired number of seconds
# Actual webcam rate is the smallest of the numbers framerate and webcam_maxrate
webcam_limit 0
control_port 8080
control_authentication admin:password
Issue #1
when I try display
http:/localhost:1234
the browser looks frozen, no HTTP 404 received but it stills waiting for data it seems ..
Issue #2
in the output directory motion writes a lot of jpeg snapshots althought I just want to have several video sequenced files.

It doesn't find the codec ...
avcodec_open - could not open codec: Operation now in progress
I've changed fmpeg_video_codec from mpeg4 to swf the result is the same.
When using flv format motion writes a lot of .jpg image but I can't see anything at http://localhost:1234

Any idea just to get the video stream recoded on my local disk ?
