Motion - Support Question 2008x 11x 09x 151456

Motion doesnt detect motion any more

Question

Hello,

I've got quite a story regarding my problem. It started when i updated my distribution from Ubuntu 8.04 to Ubuntu 8.10 The ffmpeg version was updated and motion was no longer able to save movie files.

I read the FAQ and decided to do a clean build from source. After installing some devel packages motion compiled with ffmpeg support and i started it.

After some configuration with the v4l2_palette option i got my webcam to work again. But unfortunately it didn't record motion movies.

I started debugging and enabled the periodic capture option (take a frame every second and stuff) It all worked flawlessly.

There were no error messages what so ever.

But the strange thing is, motion doesn't detect motion anymore. Even when i set the threshold as low as possible and wave my hand in front of the camera it doesnt give a kick.

It doesn't crash, it doesn't give any error message it just keeps on going.

It recored one frame a while ago, it was all green with a bit of picture on it:

The output displayed from the webcam stream is all normal.

I cant find any one who has the same problem. so decided to post my question here. I hope someone can help me. motion is my only option because ZM doesn't support my webcam. (and is just way to advanced for a one cam project)

Below is my configuration and other data that might help you. If you need any more information I'll be happy providing it for you.

Thank you very much in the advance.

Follow Up

That is image is not good at all , looks an error converting palette.

- what version of uvcvideo are you using ? ( subversion revision )

- what webcam are you using ? ( paste the output of lsusb )

Try don't force v4l2_palette value and motion will try the best , so will be easy to debug motion running :

./motion -n -d 9

Hi AngelCarpintero,

Thank you for your reply.

I dont remember installing uvcvideo from source, so i don't know what version I'm using.

Modinfo shows: version: v0.1.0

Edit: Just compiled uvcvideo from source: Revision 262

Unfortunatly no change...

Eduard i have checked uvcvideo page http://linux-uvc.berlios.de/#devices

Only this is supported :

eb1a:2761 eMPIA 2761 based camera (unbranded) eMPIA Technology

Not yours eb1a:2751, probably is easy to do it ...maybe asking in his mailing list .

Anyway looks bad that segfault probably because drivers supplied bad data but motion

should not fail.

-- AngelCarpintero - 12 Nov 2008

I did notice it isnt on the supported list, But the webstream output of motion is fine.
It worked with this webcam before the Ubuntu 8.10 upgrade.

It is only the event saving that goes wrong. the live output is just as it is suppost to be.

The strange part is that when i enable the ffmpeg_timelapse function, it just saves the frames as it is suppost to.

Only the by motion detected motion frames (which are not detected) are this weird green pictures. meaning that motion doesnt save any motion frames, exept for 3 green frames till now.

I think that the part of motion that detects motion only gets total green frames so there is no motion on it. (so it doesnt store a picture)

If you want to see it for yourself i can give you acces to my motion server. and archive folder.

-- EduartFranssen - 12 Nov 2008

New data:

I've got some new information. After hours of debugging and testing i can conclude te following:

When running motion in setup mode it displays the motion detection, and when not running in setupmode it displays the camera picture.
No problem at all.

Untill a motion event is detected, the error "Codec not found" is given.
[0] DEBUG-2 threads_running 1 motion_threads_running 1 , finish 0
[0] DEBUG-2 threads_running 1 motion_threads_running 1 , finish 0
[1] event_ffmpeg_newfile FPS 15
[1] ffmpeg_open FPS 15
[1] Codec not found: Invalid argument

[1] Thread exiting
[1] Calling vid_close() from motion_cleanup
[1] Closing video device /dev/video0
[0] Motion thread 1 restart
 

BUT!

When using the flv codec it suddenly works.
I used the following command to test this:
ffmpeg -f video4linux2 -s 640x480 -r 15 -i /dev/video0 -f flv out.avi 
the command above works
ffmpeg -f video4linux2 -s 640x480 -r 15 -i /dev/video0 -f mpeg4 out.avi
The command above does not work

After this discovery i executed the ffmpeg -formats command.

it showed a lot of codecs but i'll only list the ones involved:
D VSDT mpeg4 
DEVSD  flv
D VSD  msmpeg4

I think the E indicates that there is support for encoding, which confirms my earlier testing with the direct ffmpeg recording.

So the conclusion of this error is that I lost support for mpeg4 encoding.

the question now is how am i going to retrieve this function :P
I'm going to do some research about that now; I'll keep you posted.

Update:

I reinstalled ffmpeg from source with the xvid lib option.
ffmpeg -formats shows now:
 DEVSDT mpeg1video      MPEG-1 video
 DEVSDT mpeg2video      MPEG-2 video
 DEVSDT mpeg4           MPEG-4 part 2
 D VSDT mpegvideo       MPEG-1 video
 DEVSD  msmpeg4         MPEG-4 part 2 Microsoft variant version 3
 DEVSD  msmpeg4v1       MPEG-4 part 2 Microsoft variant version 1
 DEVSD  msmpeg4v2       MPEG-4 part 2 Microsoft variant version 2

Indicating that it should be able to encode movies.
But still no luck... neither motion nor the ffmpeg command can encode mpeg4 movies.

Update 2

I think i've made some progress, instead of crashing from "codec not found" motion now crashes with a few "Not implemented yet" errors.
It does create the file, but there is no data in it.

Any suggestions are more than welcome.

Follow up

Ok i see 2 issues :

1 -. ffmpeg has been updated and is not compatible with motion

2 -. Old an known issue with debian packages of ffmpeg that removed mpeg encoders :

http://www.lavrsen.dk/twiki/bin/view/Motion/BugReport2007x09x24x175945

Easy workaround , don't use mpeg4 codec because ffmpeg doesn't support on debian ffmpeg packages .

Better , compile ffmpeg yourself with mpeg encoders ( by default it does ).

I'll create a patch in svn trunk.

-- AngelCarpintero - 17 Nov 2008

I compiled ffmpeg with mpeg4 support, so that is working now.
That leaves motion not being compatible with my ffmpeg version.

The patch you are talking about, is that for the incompatibility issue?

-- EduartFranssen - 17 Nov 2008

No , i was talking to create a patch to detect when ffmpeg has support for mpeg encoders.

In future version of motion we not going to support any native encoder in motion, it will be using external pipe,

you can check this in svn trunk , so it's easy to encode to anything you want using memcoder i.ex .

Answer

Missing support of mpeg codec in ffmpeg libraries , a patch to detect will be added to realize quicky the issue.
