sphere driver error

Hi all,
I have a Sphere Logitech camera working properly on Ubuntu 9.10 I use Player 2.1.3. I would like to capture the camera with player and control the pan/tilt/zoom. I have tried with the sphere driver, config file: driver ( name "sphere" provides ["ptz:0" "camera:0"] port "/dev/video0" size [800 600] mode "RGB24" automatic_wb "fl" framerate 30 shutter_speed 64000 automatic_gain 10000 dump_settings 0 ) player runs properly, but I cannot subscribe to the camera. I get the error accepted TCP client 0 on port 6665, fd 7 Setting up sphere driver fg_open(): get framebuffer failed; ignoring: Invalid argument fg_open(): get memory buffer: Invalid argument error : Setup(): unable to open warning : subscription failed for device camera:0 warning : skipping subscription to unknown device blobfinder:0 If instead of the sphere plugin I use "camerauvc" it works properly, but I cannot control ptz. Some advice?? Why "sphere" does not work?? Thanks in advance. --Alberto. ------------------------------------------------------------------------------ Come build with us!

Hello,
The "broken sphere camera driver" topic returns from time to time, so I decided to buy one for my lab and see what the situation is. I've just received it so I hope I'll be able to release a patch soon (right after I finish my ranger interface collective bugfix), so stay tuned.

Hello,
BAD NEWS: I've looked at the code of sphere driver, it uses old V4L API (actually it includes headers from old-API camerav4l driver) while uvc kernel module offers only new V4L2 API (I've tried ekiga application which can easily switch between new and old API, sphere camera can be opened only using new API functions). I guess this driver might have been tested with 2.4 kernels some time ago, it won't work with any recent Linux distro. Basically, this driver must be rewritten (to look like camerauvc driver which itself uses new V4L2 API), however, as I quickly looked at it, it seems it uses extended old-V4L API funcions to control ptz capabilities of the camera. This can make rewriting job harder to complete. I can try to do that, however, for me it won't be a task of high priority, earning money have higher priority nowadays.

Some news:
1. Good: camerauvc drivers is not buggy, it works fine for me with Sphere camera on two dramatically different kernels: RedHat's 2.6.18 for Scientific Linux 5.x and vanilla kernel 2.6.30 for Gentoo Linux. 1. Bad: sphere driver code designed for old-V4L API cannot be reused to write new sphere driver, headers it uses (for PTZ ioctl's definitions) just cannot be mixed with V4L2 API. 2. Good news is that finally I've found a program that is able to operate PTZ capabilities of this camera. It is free, open source and use V4L2 API. Its name is guvcview and is available in official Gentoo portage tree (it is ~x86 masked, fortunately it works stable, tested on 2.6.30 kernel with its built-in uvc driver). The plan is to use this source code as a hint how to write new sphere2 driver (I guess we should leave old sphere driver in Player tree for those who stick with old-V4L API - old 2.6.1x kernels for embedded computers may still provide it).

Comparing to Player 3, adding new drivers to the main Player tree is not
that simple on older Players. It would be easier to release this as a plugin, however, I'd have to remind myself if threaded drivers were already introduced to Player 2.1. For now I don't remember how it was done then, fortunately, I can use Player 2.1 camerav4l driver as a template. Since I'm extremely busy this week, I'd be able to do that in the middle of next week.

Re: sphere driver error

Rate this Message:
You can probably get away with changing the names of the functions back to
2.1 API style: 3.0 2.1 void MainSetup() int Setup() void MainQuit() int Shutdown() And then change the class inheritance from public: ThreadedDriver to public: Driver After that you have to add a call to StartThread() at the end of Setup(), and StopThread() in Shutdown(). To get it to compile as a plugin driver for player 2.1, you also need some extra driver registration code. Look in ${prefix}/share/player/examples for the example plugin driver, and use that as a template. There will be one function you have to add to the source file, the one that's contained in extern "C". Then you can use the makefile in that directory as a template for building as a plugin. http://playerstage.sourceforge.net/wiki/Writing_a_Player_plugin_driver also contains a more complicated way to compile a plugin driver for 2.1, using automake. -----Original Message----- From: Paul Osmialowski [mailto:newchief@...] Sent: Friday, November 06, 2009 8:22 AM To: playerstage-users@...

Re: sphere driver error
by Elvina Motard
::
Rate this Message:
Dear Rich, Paul,
I created a player 2.1.1 plugin from the patch which compiles properly. Then I launch player with a configuration file containing the sphereptz driver and the camerauvc driver for my camera. I am able to visualize the images from the camera through playercam, but when I try to subscribe to the sphereptz through playerv, I get the following error: warning : V4L2_CAP_READWRITE check failed (ignored) error: VIDIOC_S_EXT_CTRLS failed for device ptz:0 warning: subscription failed for device ptz:0. Sounds like it can not send commands to the camera. Do you have an idea why ?

I have experienced "VIDIOC_S_EXT_CTRLS failed" in two cases: 1. when I was using Scientific Linux with 2.6.18 kernel 2. when camera firmware haned up For the first case, no help, this drivers works for me on my Gentoo Linux with 2.6.30-gentoo-r8 kernel which is rather new. If you're not sure if your camera is able to work with your kernel, try to compile and run guvcview application, if it can't compile or if it can't work it means your Linux kernel is too old. For the second case the solution was to disconnect camera USB cable for a half a minute and plug it in again. >From what you wrote I assume I don't have to prepare separate plugin anymore? I have made some patch for this driver that solves compilation problems on older 2.6 kernels but since you were able to compile it, this patch seems to be irrelevant for you.

Dear Paul,
The version of my kernel is 2.6.31-14; my camera is able to work with my kernel, since using player I can visualize the images.

Re: sphere driver error

Dear Elvina,
With the 2.6.31 kernel it should work. Also, if you can see live image from Player's camerauvc driver it gives a clue that kernel-side driver operates camera properly. Did you try guvcview utility? Can it be compiled properly on your system? My sphereptz driver uses the same code for ptz operations.
