 Hello,
 
 I am trying to get gstreamer on a Beaglebone Black. After some tries and
 looking to the example on the am335x-evmsk, i didnt get it working yet.
 So i am wondering what i did wrong, i get this message:
 
 root@beaglebone:/# gst-launch-0.10 filesrc location=HistoryOfTI-480p.m2v

 I'm running the Daisy branch without any non-custom recipes.\
 
 Hmm. I've never tried this myself. Adding Kevin to the cc' in case he's
 tried this, or can see if he gets similar results.

Hmm, I got the following resulst:
root@beaglebone:~# gst-launch-0.10 filesrc location=cinedemo.m2v ! 
mpegvideoparse ! ffdec_mpeg2video ! ffmpegcolorspace ! fbdevsink 
device=/dev/fb0 -v
WARNING: erroneous pipeline: no element mpegvideoparse

It seems that the plugins such as mpegvideoparse and fbdevsink are not
enabled for BBB BSP. Have you made any change to gstreamer recipe?

Thanks,
Kevin

[linux-yocto] [PATCH] vexpress: Pass LOADADDR to Makefile

2014-07-15 Thread Yang Shi 
Due to upstream commit 938f94cde74b33d6d3580c6fe65ebe918a770ae2
(ARM: 7656/1: uImage: Error out on build of multiplatform without LOADADDR),
vexpress BSP need LOADADDR for making uImage, so pass LOADADDR in the Makefile
for vexpress.
