I'm still having doubts about having installed PDGST propertly. When I open all of your tests patches pd can create all pdgst objects except dv1394src (linux ?), audio/x-raw and of course the one I would need : pix_gst2pix (and the reciprocal function).

while i highly appreciate a proper subject, it was not the reason for
not answering. i guess it was only so many emails you can write...

no

i don't think it's the problem. as long as you can create e.g.
[videotestsrc], gstreamer is fine.

hmm, i don't have PdGST installed on my machine here, so i cannot
properly answer that question.
iirc, there should be an example that does not involve Gem, but only
gstreamer objects. that should work,

no.

i don't think its is your fault at all.

this basically means that you have PdGST compiled against a different
version of Gem as you are using.
Gem (>=0.93) has "imageStruct::fromRGB(const char*)", whereas your error
indicates that pix_gst2pix was compiled against a Gem that has
"imageStruct::fromRGB(char*)".

make sure to point pdgst to the Gem sources that come with the 0.93.3
binaries (they should be in Gem/dev/ or so)
