A quick suggestion would be to inspect the config.txt for

Also try GPU_MEM = "256" just to make a confirmation of my

Thanks Alex. I will try that. I'm going to have another look today
and see if I can get to the bottom of it</blockquote>

Hi Alex,<br>
<br>
I've been taking a look at various things. I don't have a solution
though unfortunately at present<br>
<br>
- The GPU_MEM = "256" doesn't help unfortunately<br>
<br>
- The raspivid call is failing here, when it tries to instantiate a
camera component<br>
<br>

<br>
This seems to be because there is no supplier registered for the
camera component. Why I am not sure...<br>
<br>
...<br>
<br>
As I was investigating this I came across OpenMAX Bellagio which
seems to provide an intermediary registry of OpenMax components.<br>
<br>
I'm not sure whether this relates to the RaspiVid issue but I
believe it does relate to an issue I am seeing when I try to run a
Gstreamer pipeline<br>
<br>
gst-launch-0.10 -v videotestsrc pattern=smpte !
'video/x-raw-rgb,width=1920,height=1080' ! omx_h264enc ! rpth264pay
! udpsink=192.168.0.13 port=5000<br>
OMX-Component not found with current ST static component loader.<br>
<br>
Now apparently we are supposed to have run omxregister-bellagio
which registers up components.<br>
<br>
(omxregister-bellagio is provided by the
poky/meta/recipes-multimedia/libomxil recipe.)<br>
<br>
On Raspbian there are a set of components registered with bellagio,
and provided by individual libomx-foo packages.<br>
(e.g. libomxvideosrc.so, libomxfbdev.so, libomxclocksrc.so,
libomxcamera.so, libomxaudio_effects.so, libomxxvideo.so)<br>
<br>

<br>
These are missing on my Yocto Poky RPi image.<br>
<br>
It looks as though at some time in the past these components may
have been present in the core bellagio build, but then at some point
they were broken out into separate components tarballs.<br>
<br>
e.g. <a class="moz-txt-link-freetext" href="http://sourceforge.net/projects/omxil/files/components/">http://sourceforge.net/projects/omxil/files/components/</a><br>
<br>
I can't see recipes for these anywhere so I am wondering if they
need to be added in...<br>
<br>
Cheers,<br>
