Gnolin/Python - decoding 2 video streams

[Matt Veenstra]

Hi,

I am now trying to get 2 video streams connected end to end in gnolin
and I am still missing a some pieces.

I have 2 streams.  Each in a "gnlfilesource".  Each filesource in
"gnlcomposition".  I have a callback for "pad-added" to each
composition.  From what I have found and read.  "gnlfilesource"
handles its own decodebin.

The callback is never called in the case of 2 video streams.  I get a
decodebin error.  Below...
'gstdecodebin2.c(3135): gst_decode_bin_expose ():
/GstPipeline:mypipeline/GnlComposition:gnlcomposition1/GnlFileSource:gnlfilesource1/GstURIDecodeBin:internal-uridecodebin/GstDecodeBin2:decodebin20:\nno
suitable plugins found'

If I do the 2 audio streams this works.  And I can connect this to an
"input-selector"
If I use just gnlfilesource without the compositions I have the same
problem as well.

It still seems like I am missing something fundamental.  Do I need to
build my own input's using "gnlsource" and not "gnlfilesource"?

Thanks,
Matt
