Re: Packaging ROS for Yocto-Linux
Stefan Herbrechtsmeier <sherbrec@...>
Hi Lukas,
toggle quoted messageShow quoted text
I have interest in a ROS layer for Yocto. We are already using Yocto for your mini robot platforms but with the older player framework and our own framework. Last time I checked ROS they only support cross compiling via a native ROS installation and hide a lot of the compiling and installation process behind their own tools / scripts. Kind regards, Stefan Am 13.12.2012 09:32, schrieb Lukas Bulwahn:

You are right that 'tmp' directory needs to be removed after changing the recipe (adding inherit, or removing it). I guess we are hitting bitbake cache. Since clean tasks don't exist, 'tmp' needs to be removed to make changes take effect. I must have removed 'tmp' and missed adding it while writing. I will add the explanation. Regards, Eren -- . 73!

I'd throw in some debugging to inspect the pipelines constructed for flv vs mp4. Ross

Re: [Draft] From Bitbake Hello World To an Image
Trevor Woerner
I'm not sure if there's something about my system that is different
than what you expect, but I had to delete my 'tmp' folder before invoking './bin/bitbake firstrecipe -vDD' after inheriting the "autotool" versions in order to get the new, overridden tasks to run (since there's no 'clean' tasks).

Re: [Draft] From Bitbake Hello World To an Image
Trevor Woerner
Thank you, I enjoyed reading your document. I especially liked the top
part which talked about creating your own tasks (which 'turned the light on' for how OE/Yocto use bitbake). I also wasn't aware of the vim helpers which come as part of bitbake.

libva failing for mp4 using gstreamer under 'danny' with cedartrail BSP
Chris Tapp
I've got an X application that uses gstreamer to capture frames from video files and display them using GLES textures.
This works fine for webm and flv files, but if I try and use mp4 (or avi) then I get no frames. I'm not seeing any gstreamer errors, but the console shows: libva: VA_API version 0.32.1 libva: va_getDriverName() returns 0 libva: Trying to open /usr/lib/dri/pvr_drv_video.so libva: va_openDriver() returns 0 1) I'm building under 'danny' for cedartrail with PVR. 2) The pvr_drv_video.so file mentioned above exists. 3) The same gstreamer pipeline works fine on my host build system. 4) I'm fairly sure the required gstreamer plugins are present. Does anyone have an idea as to what might be causing this? Chris Tapp opensource@... www.keylevel.com
