gst_plugin_feature_get_name
This is a macro, the alternative:
```
import gobject.Value;
Value name;
feature.getProperty("name", name);
name.getString();
```
or if you don't want to use GValue.
```
to!string((cast(GstObject)feature.getPluginFeatureStruct()).name);
```
g_list_next

g_return_if_fail
Also a macro, witch basically does this:
```
if ( !expression )
return;

What are you thinking of when saying "ported"? gst-inspect is a good demonstration of iteration through the available gstreamer elements and their options. I want to modify that code to generate a model that could be used for persisting a pipeline configuration. https://github.com/GStreamer/gstreamer/blob/master/tools/gst-inspect.c So far, I've looked up about 80 calls used in that program, and only these few don't have c aliases in the d interfaces. I haven't looked to see if these are macros, or perhaps I could be looking at an incompatible version of gst-inspect.c. Anyway, looks pretty good so far. gst_plugin_feature_get_name g_list_next g_return_if_fail g_value_get_boolean

I use only Debian Sid and Fedora Rawhide, with occasional descent into some ancient version of MacOS (Apple refuse to upgrade older laptops, some agist excuse ;-) so I can't help with anything platform specific relating to Windows. Both Debian Sid and Fedora Rawhide have packages for GStreamer and LDC so installation is very easy. > With very little effort, though, I converted the hello_world > example to generate a video test pattern and use vidoeconvert and > autovideosink, and that popped up right away on Windows in a 64 > bit build ... so, nice going! > > The gstreamer example built without error in msvc 2013 with > visualD and DMD32 D Compiler v2.073.2 DMD is not packaged for Debian, but there is D-Apt so it is available, or Fedora, so LDC tends to be the "go to" D compiler. I haven't tried the example codes, but My GStreamer programs in D work nicely. I am just starting to rewrite Me TV from C++14 to D. -- Russel. = Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Roadm: +44 7770 465 077 xmpp: rus...@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder signature.asc Description: This is a digitally signed message part
Re: GStreamer and D
wow! I hadn't tried this gtkd library before. I was hunting for the gstreamer in particular. The hello_world alsa-sink audio example failed on Windows. The debugger indicates no sink, which I guess is reasonable. With very little effort, though, I converted the hello_world example to generate a video test pattern and use vidoeconvert and autovideosink, and that popped up right away on Windows in a 64 bit build ... so, nice going! The gstreamer example built without error in msvc 2013 with visualD and DMD32 D Compiler v2.073.2

GStreamer and D
Has anyone got any examples of using GStreamer from D. I found that GtkD packages a GStreamer API which is great, but there are very few example codes – at least that I have found. -- Russel. = Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Roadm: +44 7770 465 077 xmpp: rus...@winder.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder signature.asc Description: This is a digitally signed message part
