python2.7 bindings

Antoine Martin
Hi list,

Are there any plans to release some python2.7 bindings using ossbuild?
(any approximate release schedule?)
Are there any known issues? Is building documented anywhere I've missed?

I tried loading the project into VS2008 and after adding all the include
paths, I eventually stopped at:
"LINK : fatal error LNK1104: cannot open file 'glib-2.0D.lib'"
Does this mean I have to build the whole of gstreamer+glib+... using VS?

Every other bit of software that I use either provides a python 2.7
installer or can be installed with minimum fuss via setuptools or
distutils. pygst is the last missing piece of the puzzle...

Thanks
Antoine

Hi antoine,

You don't need to rebuild everything. We provide pre-compiled binaries
for all the external dependencies and a SDK with all the headers and a
the import libraries needed to link against gstreamer and its
dependencies. If you look close at the error, there is typo in
'glib-2.0D.lib', with and extra 'D' :)
Regarding python2.7, could you please open a new issue for that? I'll
try to have it ready in couple of days.

I was aware of the "typo" but since I didn't type anything, it must have
been generated by something in the VS build files. Which means they
don't work as-is, right?

I fixed a bunch of libraries that were misnamed in the project file: the
glib-2.0D.lib and a bunch more had libfoo.lib (unix style) instead of
foo.lib
Eventually the build went a little further, but it still failed with:

gstmodule.obj : error LNK2019: unresolved external symbol
_pygst_add_constants referenced in function _init_gst

Is this of any use to you? If so, do you want it in the bug report?

Cheers
Antoine

It's probably not appropriate to hijack the gstreamer mailing list for ossbuild-related issues. Please file an issue (bug report/feature enhancement request) at http://code.google.com/p/ossbuild/issues/entry (our email filter might add the word "blocked" to that url -- please remove it). We can discuss it from there. Thanks!

Sorry about that, I didn't realize there was a seperate mailing list for
release schedule information related questions.

You may want to add a note on the following page as this is where I
looked for rules before posting:

Gst-Editor

Is the graphical pipeline editor dead?

When I try compiling it, it wants to link against an old gstreamer.

OSSBuild is a separate, independent project and not an official GStreamer Windows build. At some point it'd be nice for that to happen, but there's still lots of work to be done before it can be accepted as such. Its main point is to provide builds of open source software -- not necessarily GStreamer-only (although at this point, realistically, that's what it's mainly targeting). It doesn't currently have a mailing list, so filing an issue on the Google code site and then starting a discussion there is how it's handled (for now). Hope that provides a bit more clarity (it's admittedly confusing).

continuous loop run of gstreamer

Kaustubh Raste
In reply to this post by Brian Michalk
Hi,

I want to create app which will continuously re-run the command-line
pipeline for x times.
I have used the example code from
"http://www.gstreamer.net/data/doc/gstreamer/head/manual/html/chapter-he
lloworld.html" to create the app.

Can this be done by using g_main_loop_run? If yes, how? (So that I need
not have to write application again)
If no, can you suggest method to do so.

NOTE: I do not want to use any player as I am using my own plugin in
pipeline.

you can find half ports on code.google.com, but those would also depend

Gstreamer, Git setup for newbie

Brian Michalk
In reply to this post by michael smith-6-3
I'm sure this is in the archives somewhere, but Sourceforge searching of
archives is terrible.

I've read the documentation for developers, and I used Git to download
the Gstreamer code, but the documentation is a bit light on exactly
where the plugin directories need to go, and which files are being
edited for configuration.

Do all GIT downloads go into the same directory, or should I cd into the
gstreamer directory and git download the plugins to there?

I'm compiling from tarballs now, and that seems to be going much better.

separate folders are better. I wrote the scripts here for my personal
use, but maybe they'll give you  basci idea of how the thing works:

Re: continuous loop run of gstreamer

Sudarshan Bisht

   You can use this example and do slight modification in bus callback, i.e. whenever bus callback receives EOS , instead of quiting the loop play pipeline again.
And once your counter (as you want to run it x times) hits the mark then quit the loop.
