Hi guys,

I've been doing some research but i can't seem to get my head around what i'm doing wrong.
i'm having problems displaying video from /dev/video0

with mplayer i just get a green screen. when i ctrl-c i get a black screen and have to hard reboot the pi.
When i use mplayer to write the capture to a file, i get an empty file.
i use the following command to try and display the video capture device.

Code: Select all

mplayer vcd:///dev/video0 -dumpstream -dumpfile out.raw & omxplayer out.raw -o hdmi

When i use cvlc to open the capture device i get the following message.

-- logger module started --
main error: no suitable interface module
main error: interface "globalhotkeys,none" initialization failed
dummy: using the dummy interface module...
vcd error: could not read TOCHDR
vcd error: no movie tracks found
main error: open of `vcd:///dev/video0' failed
main error: Your input can't be opened
main error: VLC is unable to open the MRL 'vcd:///dev/video0'. Check the log for details.
-- logger module stopped --

command:

Code: Select all

cvlc vcd:///dev/video0 --logfile=vlc.log --file-logging

I have the following capture device

This is just to test if i can capture the video device.

The ultimate goal is to capture the video device and output the content to a mounted network drive. no displaying on the pi is required.

Hope someone can help me with this.

Thx

Does dmesg show any noteworthy error messages in the log??

As for video capture in general this doesn't perform well on the Pi because the ARMv6 processor isn't fast enough or suitable for processing video data especially at 720/576 resolution.
Unless your capture device provides hardware encoding i.e. mjpeg/mp4/mp2 then you're going to have to sacrifice frame rate and resolution to make this workable on the Pi.

i'm no dmesg expert so i'll just post the contents.

the device is a GrabBeeX+ Video Encoder btw

How do you want to transfer 20 Megabyte/sec. across the network (if you get it to work)?. HW h264 encoding (using gstreamer-1.0 perhaps) might be the only solution.

This part is quite clear..

I think you may be able to add to /etc/modules

Code: Select all

em28xx card=6

To have it choose one of the 89 different configurations. ( 6 was just chosen because I saw Terratec was mentioned together with GrabBeex in a google search )

thanks for the usefull information. but i'm not very hany with unix.

i created a file called em2710 in /etc/modprobe.d.
there i added

Code: Select all

options em2710 card=21

since that is the actual vendor if the device.
dmesg still displays the same messages.

Posted: **Tue Jul 01, 2014 1:08 pm**

i renamed the em2710 to em2820.conf and changed the code inside to
options em2820 card=21
but that still didn't help.

Posted: **Tue Jul 01, 2014 1:24 pm**

I didnt put "xx" in my example as a variable, the module is really called "em28xx".

Code: Select all

find /lib/modules/ -name "em28*"

Posted: **Tue Jul 01, 2014 1:39 pm**

your command delivered some results

/lib/modules/3.12.22+/kernel/drivers/media/usb/em28xx/
/lib/modules/3.12.22+/kernel/drivers/media/usb/em28xx/em28xx.ko

/lib/modules/3.12.22+/kernel/drivers/media/usb/em28xx/em28xx-rc.ko

which file do i change?

Posted: **Tue Jul 01, 2014 1:58 pm**

ok, i changed the file under /etc/modprobe.d/.
now the drivers seem to load fine but i still get the message that video0 can't be opened
