hello,
I would like to do something with my huge ( 3+ TB) video footage from CCTV
cameras.
I would like to extract motion data only (images+video). There is no hardware
camera, and there isn't any stream.
I have only .mp4 files which I would like to analyse.
Is that possible? I have tried to custmomize the .conf file:
###########################################################
# Capture device options
############################################################
# Videodevice to be used for capturing (default /dev/video0)
# for FreeBSD default is /dev/bktr0
videodevice /media//085a6e19-7de4-438e-8988-8c06d34a7863/k4m/20171003/17_c28.mp4
As a path to the specific file - comes from the cctv camera in past.
But after 2 minutes after start I have got similar messages in log:
[1:ml1] [WRN] [ALL] [Oct 10 22:20:10] motion_loop: Retrying until successful
connection with camera
[1:ml1] [NTC] [VID] [Oct 10 22:20:10] vid_v4lx_start: Using videodevice
/media/085a6e19-7de4-438e-8988-8c06d34a7863/k4m/20171003/17_c28.mp4 and input -1
[1:ml1] [ERR] [VID] [Oct 10 22:20:10] v4l2_get_capability: Not a V4L2 device?

/media/085a6e19-7de4-438e-8988-8c06d34a7863/k4m/20171003/17_c28.mp4
[1:ml1] [DBG] [ALL] [Oct 10 22:20:10] motion_loop: vid_return_code 1
[1:ml1] [DBG] [ALL] [Oct 10 22:20:10] motion_loop: vid_return_code 1
[1:ml1] [DBG] [ALL] [Oct 10 22:20:10] motion_loop: vid_return_code 1
I know the ffmpeg should help me, but I have problems with finding good
documentation about that. Motion looks very interesting and has all features
which I would like to use, so... I would really like to try to use it.
If the file input is not best solution, I can try to convert this file into any
videostream - from ffpmeg.

This is possible via streaming the file via ffmpeg to a v4l2 loopback
device and then running motion on that device.? The flow would be
static file -> ffmpeg->v4l2 loopback device ->motion
See the static file section in the basic setup of the motion guide
http://htmlpreview.github.io/?https://github.com/Motion-Project/motion/blob/master/motion_guide.html#Basic_Setup
as well as the v4l2loopback setup section
