I've successfully patched our gstreamer plugin to build with gstreamer-1.0, but how do I test it? Does someone have a sample document that uses gstreamer?

The patch is attached for anyone interested. Parts may still be wrong, eg. filter names. Changes between GStreamer 0.1 and 1.0 are documented here:

I've begun having a look.

We currently test for gstreamer in configure.ac but don't use the result, re-running pkg-config in a main/avmedia's makefile.

Changing the version number to 1.0 breaks the build due a missing header file. Removing that "#include" gets it a little further, but it breaks due to changed gstreamer API functions. There is also lots of warnings about deprecated GDK functions. I'll continue trying later.

We should really get rid of gstreamer 0.1 ASAP one way or the other: given how it's been unmaintained since 2013, it may well have security vulnerabilities. We can't ship it to users since its license is incompatible, but having users install it separately still invites trouble.

Hello, Peter.

Thank you for reply and for adding additional info into AOO wiki.

Yes I'm posted on that project is short of developers this time.
I hope that current implementation still will hold several years
because gstreamer-0.10 of long process of skiping this brach
in linux distributibes.

Maybe during this transition period at least the way to  standalone build
of appropriate multimedia AOO library will be found if it possible at all.

Unfortunately I suppose I have no enough programming skills
to understand how build system works and the difference between gstreamer-0.10 and 1.0 API/ABI .
