I am having a few issues with gstreamer on wandboard-quad using Dora
branch with kernel 3.0.35-4.0.0. I have been using fsl-image-test
with extra packages loaded from local.conf for easy testing. The
first issue I have is that gst-plugins-base is missing the pango
plugin. Is this intentional or a bug? How can I add it in?
Second, I am having difficulty with the alpha channel when using
mfw_v4lsink. Because I am using fsl-image-test, the console is always
present. Setting VSALPHA=1 does nothing. If I change the sink to
mfw_isink it all works, but I don't want to use isink at the moment.
How can I either: a.) Fix the alpha blend with v4lsink, or b.) get
rid of the console in the background?
When using multioverlay with mfw_isink with console commands (and
following this doc: https://community.freescale.com/docs/DOC-93788)
when the video file reaches the EOS, the VPU crashes and prints the
following to the screen:
Got EOS from element "pipeline0".
Execution ended after 108164009014 ns.
Setting pipeline to PAUSED ...
Setting pipeline to READY ...
Can not open dll, libgstfsl-0.10.so: cannot open shared object file:
No such file or directory.

Spinning. Please run 'gdb gst-launch 1684' to continue debugging,
Ctrl-C to quit, or Ctrl-\ to dump core.
This forces me to reboot the board in order to use the vpu again. Gdb says
#0 0x40180e14 in ?? ()
#1 0x40180e04 in ?? ()
#2 0x40180e04 in ?? ()
Backtrace stopped: previous frame identical to this frame (corrupt stack?)
Lastly I am not able to display jpeg images. Following this tutorial
(https://community.freescale.com/docs/DOC-93790), results in the error
'source fmt error'. I have Tried with multiple jpegs of different
resolutions from different sources, all with the same result. This
also seems to lock up the VPU, forcing a reboot in order to play video
again.
Thanks for the help
