VoCore: MJPG Camera

Prepare:
1. necessary library(openwrt must have video support)
(if you do not know how to compile it, download here packages, or full firmware(no luci):
kmod-video-core_3.14.25-1_ramips_24kec.ipk
kmod-video-uvc_3.14.25-1_ramips_24kec.ipk
kmod-video-videobuf2_3.14.25-1_ramips_24kec.ipk
libjpeg_9a-1_ramips_24kec.ipk
mjpg-streamer_r182-2_ramips_24kec.ipk

copy all of them to vocore:
scp kmod-video-core_3.14.25-1_ramips_24kec.ipk root@192.168.61.1:/tmp/
scp kmod-video-videobuf2_3.14.25-1_ramips_24kec.ipk root@192.168.61.1:/tmp/
scp kmod-video-uvc_3.14.25-1_ramips_24kec.ipk root@192.168.61.1:/tmp/
scp libjpeg_9a-1_ramips_24kec.ipk root@192.168.61.1:/tmp/
scp mjpg-streamer_r182-2_ramips_24kec.ipk root@192.168.61.1:/tmp/

ssh to vocore, install:
opkg install /tmp/kmod-video-core_3.14.25-1_ramips_24kec.ipk
opkg install /tmp/kmod-video-videobuf2_3.14.25-1_ramips_24kec.ipk
opkg install /tmp/kmod-video-uvc_3.14.25-1_ramips_24kec.ipk
opkg install /tmp/libjpeg_9a-1_ramips_24kec.ipk
opkg install /tmp/mjpg-streamer_r182-2_ramips_24kec.ipk

2. one usb mjpg camera. mine get from taobao.com, cost about 12USD.

3.a vocore, need to connect with USB D+/D- and give the webcam 5V power.
3.b vocore + dock, this is much easier, directly connect to dock usb port.

Now, run

/usr/bin/mjpg_streamer -i "input_uvc.so -d /dev/video0 -resolution 320x240" -o "output_http.so -www /www/webcam"

(Note: “/etc/init.d/mjpg-streamer start” not working, have to call it directly)

Try with your browser 🙂 Plan to write a plugin for vohttpd, to make this easier.

Looks like my webcam is a little short sight…

    I have an installation error:

    Collected errors:
    * opkg_install_pkg: Package kmod-video-core md5sum mismatch. Either the opkg or the package index are corrupt. Try ‘opkg update’.
    * opkg_install_cmd: Cannot install package kmod-video-core.

    I think it happened becouse the packages were compiled for another kernel version. Can i install it without compiling? Or can you give me instruction how to compile it, please?

      Download openwrt from git, run make menuconfig, you need to check
      Kernel modules -> USB Support -> kmod-usb-core,kmod-usb-ohci,kmod-usb2
      Kernel modules -> Video Support -> kmod-video-core, kmod-video-uvc,kmod-video-videobuf2
      Multimedia(update feeds first) -> mjpeg-streamer -> Install uvc plugin, Install output http plugin
      Libraries -> libjpeg

      Then call make, you will get ipk files in bin/ramips/packages.

    Good afternoon!

    I have VoCoro and 4 UVC Cameras (So shows v4l-info)
    2 Cameras bought on aliexpress (no name)
    2 Cameras: Logitech C510 and Creativ I don’t remember model

    And so a problem in the following if I connect the Chinese cameras that MJPG streamer via the browser simply hangs also all. something is loaded constantly by the page. Happens loads also simply white screen.

    With C510 and a creative all all right. Matter in drivers?

    Still there is C510 Not at once is connected. MJPG also loads in the browser and only after couple of times of reconnections (~ / mjpg_streamer) the camera starts showing the picture. VoCore doesn’t manage to process data?

    P.S. from 32 Mb of a RAM it shows only 16. I start with parameters (/usr/bin/mjpg_streamer – i “input_uvc.so-d/dev/video0-resolution 320×240” – o “output_http.so-www/www/webcam”)
