it was a FlyCamOne2 on/in the removable Funjet cockpit. The video was
recorded to a SD card on-board and not sent down. I do not recommend
this camera (at least for operation in the Arctic). Results were very
random at low temp.

 

Thank you for the info. I use the same camera strapped to the wing of my easy glider. In temperate New Zealand it is fine. 

 

I have another video problem you may help me to resolve.

 

I recently upgraded (complete iso reinstall) my dell laptop to dell unbuntu 8.10 (intrepid). kernel 2.6.27

 

I cannot load the mercurial em28xx drivers as per the wiki to make Pollin USB R1 receiver work.

 

I understand the linux org dvb em28xx drivers are preloaded on this distro and are probably stopping me from 

loading the correct mercurial drivers.

 

Do you have any ideas?

 

After three days and three new reinstalls I have reached my wit's end and obviously no video. 

    

Regards

Dear Martin  and others,

 

I have made some progress

Managed to patch Linuxtv.org em28xx devices software:
www.linuxtv.org/wiki/index.php/Em28xx_devices

-Added the following to:
v4l-dvb/linux/drivers/media/video/em28xx-cards.c

  } },
},
        [EM2861_BOARD_POLLIN_USB_R1] = {
.name         = "Pollin USB-R1",
                .valid        = EM28XX_BOARD_NOT_VALIDATED,
                .vchannels    = 1,
.tuner_type   = TUNER_ABSENT,
.decoder      = EM28XX_SAA711X,
.input           = { {
.type     = EM28XX_VMUX_COMPOSITE1,
.vmux     = SAA7115_COMPOSITE0,
.amux     = EM28XX_AMUX_LINE_IN,
} },
},

-Added the following to:
v4l-dvb/linux/drivers/media/video/em28xx-cards.h

#define EM2861_BOARD_POLLIN_USB_R1   66


-Added the follwing to /etc/modprobe.d/emb28xx (as the Pollin USB-R1
does not have an EEPROM for auto detect.)

options em28xx card=66

After make and sudo make install video is visible on mplayer using the
following instruction: mplayer tv:// -tv
driver=v4l2:width=320:height=240:norm=NTSC:input=0:device=/dev/video0:noaudio

The terminal output is as follows:

Vlc will not play the video camera output.

Spook will not work with: vlc rtsp://localhost:7070/webcam or with
mplayer.

Spook terminal output is as follows:

The first session error is reported when activation is undertaken when
mplayer is running. The second session is with just the camera running
under 4vl-dvd.
