Hi. I am trying to implement gstreamer install plugins. Can someone take a look at the attached patch ? Documentation can be seen at [http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstpbutilsinstallplugins.html](http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-base-libs/html/gst-plugins-base-libs-gstpbutilsinstallplugins.html) ---

Hello, Perhaps it could just be added to Ruby-gnome? If problems result from this users could email you? Gstreamer is nice but I remember it was not easy to keep maintaining it. (Documentation about Gstreamer is also not perfect yet in my opinion.) ---

It seems that RG\_DEF\_CONVERSION isn’t needed. Do you have a sample script that needes RG\_DEF\_CONVERSION? 2. GstInstallPluginsReturn in gst\_install\_plugins\_result\_func(), async() and sync() should convert by GENUM2RVAL(result, GST\_TYPE\_INSTALL\_PLUGINS\_RETURN) not INT2FIX(). 3. block in async() shuold be guarded from GC by keeping a reference to block. You can use G\_RELATIVE(self, block). (You need to unreference the block after the block isn’t needed. But I don’t have English skil to explain how to do it.

I guess best solution should : use G\_CHILD\_ADD in place of current G\_RELATIVE, unreference the block inside gst\_install\_plugins\_result\_func function with G\_CHILD\_REMOVE macro. It requires to pass both the block and mGstInstallPlugins to the gst\_install\_plugins\_result\_func function. I guess it is possible by using the last argument of the function. In gst-install-plugins5.diff I have try another solution. I store the block in an Array object which is an (hidden) instance variable of Gst::InstallPlugins. I delete the block from the array after use. ---

Ah, you’re right. Could you commit gst-install-plugins6.diff instead of 4.diff? ## Thanks, kou ---

I delete the block from the array after use. It will work but we want to use common way to do the same thing. (keeping block’s reference) I think that gst-install-plugins4.diff with comment about G\_CHILD\_ADD() and G\_CHILD\_REMOVE() is better patch in your 3 patches. Please commit it! ## Thanks, kou ---
