it's a bug in the original dshowaudiosrc, as you can see in around line 360 of <a href="http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/sys/dshowsrcwrapper/gstdshowaudiosrc.c">http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/sys/dshowsrcwrapper/gstdshowaudiosrc.c</a> there is no PROP_DEVICE_NAME case in the switch. <pre><code>static void gst_dshowaudiosrc_set_property (GObject * object, guint prop_id, const GValue * value, GParamSpec * pspec) { GstDshowAudioSrc *src = GST_DSHOWAUDIOSRC (object); switch (prop_id) { case PROP_DEVICE: { if (src->device) { g_free (src->device); src->device = NULL; } if (g_value_get_string (value)) { src->device = g_strdup (g_value_get_string (value)); } break; } default: G_OBJECT_WARN_INVALID_PROPERTY_ID (object, prop_id, pspec); break; } } </code></pre>The fix is in the patch. <div class="gmail_quote">2009/3/18 <<a href="mailto:cammille@polytech.unice.fr">cammille@polytech.unice.fr</a>> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">In the sound properties on WIndows, my device to capture the sound is named : "Realtek HD Audio Input" So I try : gst-launch-0.10.exe dshowaudiosrc device-name="Realtek HD Audio Input" ! audioconvert ! vorbisenc ! oggmux ! filesink location=bar.ogg But I have an error which is : ** (gst-launch-0.10:77172): WARNING **: ..\..\sys\dshowsrcwrapper\gstdshowaudios rc.c:378: invalid property id 2 for "device-name" of type `GParamString' in `Gst DshowAudioSrc' <div><div></div><div class="h5"> > 2009/3/18 <<a href="mailto:cammille@polytech.unice.fr">cammille@polytech.unice.fr</a>> > >> I would prefer to not recompile dshowaudiosrc if it's possible. >> My microphone is not muted.
