Motion - Linux Uvc Tracking Patch
You are here: Foswiki>Motion Web>LinuxUvcTrackingPatch (09 Aug 2007, AngelCarpintero)Edit Attach

Patch for support Motion tracking feature with linux-uvc devices

Description of Patch

To enable tracking for Logitech Quickcam Sphere (046d:08c2) which use linux-uvc driver I had written uvc_center and uvc_move function inspired by original lqos_center and lqos_move function.

Installation of Patch

Download the patch file. If it is packed as a gz or tar.gz unpack it first. Then copy it to the motion source directory and issue the command (assuming the patch file is called filename_of_patch_file.diff)

patch < filename_of_patch_file.diff

Then re-build Motion and test the patch.

Discussion and Comments


On my Bus 001 Device 002: ID 046d:08c2 Logitech, Inc.

I get : [1] Failed to move camera!: Input/output error [1] File of type 1 saved to: /usr/local/apache2/htdocs/cam1/01-20060709014719-00.jpg

on kernel log i get: uvcvideo: Failed to query (1) UVC control 1 (unit 9) : -32.

ps: i've set the TRACK_TYPE to 5 do i have to modify something else?

Thx

I track down the problem, i can't explain. but here it is:

When vd->formatIn is set to V4L2_PIX_FMT_YUYV the control (pan/tilt) do not respond. if i set to V4L2_PIX_FMT_MJPEG it works. ( But "Motion" is not prepared to accept this format ).

-- FabioYamamoto - 10 Jul 2006

I gonna try to merge your patch with current svn version revision 163 , but the API of uvcvideo has changed so i will introduce some changes.

-- AngelCarpintero - 25 Jan 2007

I have problem with tilting. Panning works ok, but tilt aint. My device is also 046d:08c2 Logitech, Inc. Logitech Sphere and using with V4L2_PIX_FMT_MJPEG ok. Is there any solution in this tilt problem?

-- PeterBowle - 20 Feb 2007

Same problem as PeterBowle :

uvctrack.diff applied to latest daily snapshot : panning OK, tilting KO

everything was allright with 3.6 release sources.

-- JeromeV - 26 Feb 2007

in the version 3.8.1 I get only mad moves - up&down nothing left&right sometimes and not clear. My cam is a 08CC. This I can see, if I start the uvcvideo with tracelevel 15:

One information more:

Motion - daily bind from the 14.03 / uvcvideo = daily from 13.03

I have try it in the morning also via a M$ IE and it works better as the Konquerer. The problem of Peter Bowle, I've too. I use the script and html for try from : http://www.lavrsen.dk/twiki/bin/view/Motion/LogitechSphereControl

with all the buttons at the webpage ( not the last - for testing the first is better ).

and

up and down at the buttons from the web will move the Cam left and right ! Left and right at the buttons from the webside will NOT move the Cam. I think, there is only a little count error somewhere ?

-- DirkWesenberg - 15 Mar 2007

The HTTP/1.0 204 No Content trick works on all browsers - except some older versions of Konquerer that seems to react the wrong way to this.

-- KennethLavrsen - 15 Mar 2007

Hi I am having a similar problem. I have everything working apart from tilt. Pan is fine but I get no response to tilt. Any help much appreciated

-- PaulMcclung - 17 Mar 2007

Upps - I does not want override the old patch.... I have modified the old patch and split the pan/tilt function into 2 calls. I know it will be going better, but in C I'm a bloody beginner. Feel free to test also and/or change the 2 single calls of the procedure VIDIOC_S_CTRL to one call via VIDIOC_S_EXT_CTRLS .... Tested with the motion of daily from 15.3.07 of motion and the daily of 15.3 of uvcvideo with the Kernel 2.6.20-4 PPC.

There is a small bug in the patch: I'll update later today ( Pan does not work anymore [all pan.tilt value must be in tilt ] ). Pan is working, but not long ... Maybe a small pause must be in ...

I try to rewrite the function - Yesterday Tilt was working w/o any problems, but Pan was going over the limit (first pan was working)... The pan&tilt via picture coordinate is in the first step disabled. At first the normal PAN&TILT must be working. I'm sorry that it is not going faster, but I've no experience with C ( more in Assembler ) ... maybe at the evening, I'll have a result.

-- DirkWesenberg - 28 Mar 2007

The Motion_Logitech_MP_Tracking.diff is now working with uvcvideo ( 03/07) and motion 3.2.8 with a Logitech Sphere MP refresh.

Relative PAN=7777 is also a PANTILT Reset. Also if first only relative working and than the switch to absolut is now working, because I reset the Webcam at first use. The Min & Max is fixed in Code, because the function is not included just now. Also the prgramming is not the best:I know-but it is my first C prog-Part. I hope, I have nothing forgotten, because M$ Controll char is must recopy in a orig track.c file. Have fun !

-- DirkWesenberg - 30 Mar 2007

Thanks , added to current svn trunk , i did some ident on code ... still i didn't check it i'll try to get a webcam or someone that allow me to test one.

-- AngelCarpintero - 31 Mar 2007

Continue: During I try to change the patch about Pan&Tilt I see, that the WebCam Logitech 0x08cc handle also digital zoom. I think that is also hardware controll. In V4L2 I've found the procedure : VIDIOC_S_CROP Does someone have try, to implement this feature ?

-- DirkWesenberg - 18 Apr 2007

The current patch it's already in current beta ( 3.2.8 beta 1) , so new patches will be against this beta version.

-- AngelCarpintero - 21 Apr 2007


I am having a similar problem with uvcvideo with original Logitech Orbit MP (046d:08c2) on Linux 2.6.20-16-generic using Motion 3.2.8 b1 (as well as latest snapshot). If I plug the camera into a USB 2.0 port, YUYV is used in Motion and I get a decent picture with flickering and no tracking. If I plug the camera into a USB 1.1 port, MJPG is used in Motion and the picture has funny colors, but the tracking works. Using the camera with luvcview (v0.2.1), the camera has a clear picture and tracking works with either USB 1.1 or 2.0 and generally get 13-16 fps.

-- BiehlD - 19 Jul 2007

I'm going to commit a patch to svn that fix the color issue, there was a previous patch that fixed that issue already but using libmjpegtools :

http://www.lavrsen.dk/twiki/bin/view/Motion/MjpegToYUV420pPatch

But was not very smart to introduce another dependency , so i hope the next commit fix finally the color issue.

Take a look to this new topic :

-- AngelCarpintero - 24 Jul 2007

After applying the patch mentioned in http://www.lavrsen.dk/twiki/bin/view/Motion/MjpegColorIssue to release 200, I get a seg fault when I run Motion. Motion starts up, and reads the camera controls, then seg faults.

SEG FAULT

Motion v3.2.8 still has the same color issues with the Logitech Orbit MP (046d:08c2). The strange colors appear more as the satuartion is increased. Email me if you need additional info.

-- BiehlD - 02 Aug 2007
You're right my patch segfault , i didn't notice before because seems that my camera ( using uvcvideo ) gets jpegs without problems , so there's no problem with huffman table , strange though. I'll work on this.

-- AngelCarpintero - 06 Aug 2007
I've added the old patch against current svn version ( -r201 )

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

-- AngelCarpintero - 08 Aug 2007

FYI:

r201 with mjpeg-color-issue.diff (from messages log)....

motion: [1] ^I"Power Line Frequency", default 2, current 2
motion: [1] Missing huffman table ... fixing
last message repeated 9 times
motion: [1] Removed process id file (pid file).
(motion quits automatically)

r201 with mjpeg2-r201.patch (while patching)...
patching file Makefile.in
patching file video.h
patching file video2.c
Hunk #1 succeeded at 828 with fuzz 2 (offset 42 lines).
patching file video_common.c
Hunk #2 succeeded at 396 (offset -1 lines).

r201 with mjpeg2-r201.patch works and color problem is fixed...Thank You!

-- BiehlD - 09 Aug 2007

Ok , seems that mjpeg-color-issue.diff mess jpeg :-/

So mjpeg2-r201.patch with mjpegtools dependency is in svn trunk until there's not a best approach.
