Re: [Gumstix-users] Overo Waterstorm using Yocto, Caspa not working properly, No such driver: v4l2

[takeoo111111 <tak...@go...>]

Hi,
I used the configuration of caspa-stream-raw but without the package
installed. As there was no error using gstreamer, I thought all necessary
plugins would be there already.
After installing it (from repository), it works. But the network stream is
very very slow (lag >30 sec) even if I use Jpeg compression with a very low
resolution and quality.
But, as we are not planing to use a video stream (just single frames) it
seems to be OK for us. 

However Mplayer is still not working, showing the same error as before. Even
preloading does not help.
LD_PRELOAD=/usr/lib/libv4l/v4l2convert.so mplayer tv:// -tv
driver=v4l2src:device=/dev/video6 -vo png -frames 1
As gstreamer is working I think hat the problem is located somewhere in
mplayers configuration files. But I seems everything alright to me.

You are right Thijs, it was OK for testing but is way to old to use it in an
productive environment.

Of topic:
We are going to use the system, as an student experiment (PATHOS-REXUS), for
horizon detection in an REXUS sounding rocket under space like conditions
(up to 100km height). Therefore the system is tested under extreme 
conditions ( e.g. down to 10^-4 bar,  very fast rise from -40 to 60°C, 100g
shock...). If someone is interested in the test results, don't hesitate to
contact me.
