<div dir="ltr"><div>As you may know the Pidgin IM client uses gstreamer and farstream on Linux, but that capability hasn't been implemented on Windows. The Pidgin IM client uses a MinGW build system with some specialized build instructions at <a href="https://developer.pidgin.im/wiki/BuildingWinPidgin">https://developer.pidgin.im/wiki/BuildingWinPidgin</a>. I'm attempting to get gstreamer/farstream working in Pidgin on Windows.<br>
<br>After a lot of effort, I got things to compile and start up by:<br><ul><li>Making some MinGW build tweaks to farstream itself, described at <a href="https://bugs.freedesktop.org/show_bug.cgi?id=62793">https://bugs.freedesktop.org/show_bug.cgi?id=62793</a></li>
<li>Downloading precompiled binaries for gstreamer 1.1.0.1, glib 2.32, GTK+ 2.24, etc. as described at <a href="http://pidgin.10357.n7.nabble.com/Video-Voice-on-Windows-progress-fails-to-load-fsrtpconference-plugin-td125410.html">http://pidgin.10357.n7.nabble.com/Video-Voice-on-Windows-progress-fails-to-load-fsrtpconference-plugin-td125410.html</a>. (Note that I've since rebuilt libnice 0.1.4 from scratch just fine under MinGW using a pregenerated ./configure.)</li>
</ul></div><div><div><div></div><div>With GST_DEBUG set to '*:9', as Pidgin starts up I can see that some plugins are loaded just fine and others fail. It looks like:<br><ul><li><b>fsmsnconference</b>, <b>fsrtcpfilter and fsrtpconference fail to load</b></li>
<li><b>fsrawconference, fsvideoanyrate load just fine </b></li></ul>For "deployment" of the plugins I just copied the DLLs to C:\Users\cp\.gstreamer-1.0, set GST_PLUGIN_PATH to point there, and copied other dependent DLLs into the pidgin.exe directory. Using Dependency Walker seems to show no missing dependencies. So I guess I wonder if anyone has any thoughts on:<br>
<ul><li>What kinds of things would cause loading a plugin to fail?
</li><li>Can you suggest any extra debugging steps I might try?
</li><li>Do you see a pattern in terms of which plugins load and which ones fail that might point me in the right direction?<br></li></ul>I appreciate any help you can offer. Thanks!<br><br></div><div>-- Conrad<br><br><br>
