USB issues with gst-launch pipeline on Beagle Board (was: [beagleboard] Re: Use case as a HTPC with VDR)

[Paul Menzel]

Dear GStreamer-devel list,


there are some efforts to get VDR going on the Beagle Board [1]. One
option to use GStreamer for output [2]. But there are USB related
problems.

This is the quote from [1].

Can you give some hints to improve this pipeline? Do you see a problem
with it? Where can this problem be reported to?

Sorry for those questions. I must admit my head explodes getting to know
all this new stuff for me. So it would be really nice if you could point
to some information or give some hints and forgive me if I overlooked
something on the Web.


Thanks in advance and bests,

Paul
