Help for dshowaudiosrc

Hello,

I'm trying to use dshowaudiosrc on Windows but I have some problems.

For example, I try :

gst-launch-0.10.exe dshowaudiosrc ! audioconvert ! vorbisenc ! oggmux !
filesink location=foo.ogg

And hen I talk in my micro the file foo.ogg is empty.
I already verified if my micro functions correctly. It does.

If I try :
gst-launch-0.10.exe audiotestsrc ! audioconvert ! vorbisenc ! oggmux !
filesink location=foo.ogg it works !

Where is the problem ?

Re: Help for dshowaudiosrc

Hi,

2 solutions.

****The first one (user) is to click on volume icone from task bar then Options->properties then select "Enregistrement" ("Recording") then select microphone then OK then unmute microphone.

****The second solution (using code), is to recompile dshowaudiosrc using this patch:
http://bugzilla.gnome.org/show_bug.cgi?id=517203 (just see the last post)

Then the following code could be used to list, select and configure the input channel of your choise (S/PDIF, lineIn, Mic etc..)

----------------------------- list audio input ------------------------
vector<string> listAudioInputs(const string audioDeviceName)
GstElement* audiodevicesrc = create_element("dshowaudiosrc", "audiodevicesrc");
g_object_set(G_OBJECT(audiodevicesrc), "device-name", audioDeviceName.c_str(), NULL);

GstPad* pad = gst_element_get_static_pad (audiodevicesrc, "src");
gst_pad_get_caps (pad);
if (pad)
     gst_object_unref(pad);

vector<string> l_inputs;
GstMixer *mixer = GST_MIXER (audiodevicesrc);
const GList* list = gst_mixer_list_tracks (mixer);

for (const GList* item = list; item != NULL; item = item->next)
{
    GstMixerTrack *track = (GstMixerTrack*)item->data;
     l_inputs.push_back(string(track->label));
}

if (audiodevicesrc)
{
     gst_element_set_state (audiodevicesrc, GST_STATE_NULL);
     gst_object_unref(GST_OBJECT (audiodevicesrc));
}

return l_inputs;
}
------------------------------------------------------------------------------------------------------

---------------------------- select record input and set volume -------------------------------------
void setAudioInput(const string audioInput, int volumePercentOfMax)
{
GstMixer *mixer = GST_MIXER (audiodevicesrc);
GstMixerTrack *track = NULL;
const GList* list = gst_mixer_list_tracks (mixer);
for (const GList* item = list; item != NULL; item = item->next)
   {
      GstMixerTrack *track_next = (GstMixerTrack*)item->data;
      if (audioInput == std::string(track_next->label))
           track = track_next;
        else
           //mute other audio inputs
           gst_mixer_set_mute(mixer, track_next, TRUE);
   }
if (track)
{
vector<gint> volumes(m_audioNbChannels, (gint)(volumePercentOfMax * track->max_volume / 100.0));
     gst_mixer_set_record (mixer, track, TRUE);
     gst_mixer_set_volume (mixer, track, &volumes[0]);

}
}

------------------------------------------------------------------------------------------------------

They are some bad things in this code but the idea is there.

You can also use property probe on dshowaudiosrc to list all the audio device names installed on your system.

Help for dshowaudiosrc

I would prefer to not recompile dshowaudiosrc if it's possible.
My microphone is not muted. So I don't understand why it didn't work. With
the windows magnetophone I can register my voice. Very strange...

I don't find any information about property probe.. so I don't know how to
use it.

Re: Help for dshowaudiosrc

I would prefer to not recompile dshowaudiosrc if it's possible.
My microphone is not muted. So I don't understand why it didn't work. With
the windows magnetophone I can register my voice. Very strange...

Maybe how are not using the device you are excepting to use. In panel configuration, sound, you can see if you have several audio devices. If yes, you have to set device name on dshowaudiosrc. (check the volume too)

I don't find any information about property probe.. so I don't know how to
use it.

Re: Help for dshowaudiosrc

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'

Re: Help for dshowaudiosrc

it's a bug in the original dshowaudiosrc,

as you can see in around line 360 of http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/sys/dshowsrcwrapper/gstdshowaudiosrc.c
there is no PROP_DEVICE_NAME case in the switch.

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;
  }
}

The fix is in the patch.

2009/3/18 <[hidden email]>

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 :

Re: Help for dshowaudiosrc

Hi,

Try with the files in attachment.
I will investigate if you get the same error.

Le 19 mars 2009 12:08, <[hidden email]> a écrit :

Hello,
Si je ne me trompe pas vous êtes français. Alors ça sera beaucoup plus
simple pour moi de vousparler en français.

Voilà je suis allé sur cette page :
http://bugzilla.gnome.org/attachment.cgi?id=126508&action=diff

Et j'ai fait les modifications des fichiers gstdshowaudio.c et .h.
J'ai ensuite créé les fichiers :
- gstdshowaudiomixertrack.h
- gstdshowaudiomixertrack.c
- gstdshowaudiomixer.h
- gstdshowaudiomixer.c

Si je ne me trompe pas on en a besoin...

Le problème est que lorsque je compile j'ai des erreurs du type :
Erreur 3 error C2014: une commande de préprocesseur doit commencer comme
premier espace autre que
blanc c:\gstreamer-winbuild\gstreamer\gst-plugins-bad\sys\dshowsrcwrapper\gstdshowaudiomixer.h 164 libdshowsrcwrapper

L'erreur est à cette ligne : interface_as_function ## _supported (Type
*this, GType iface_type)

Et donc à partir de là j'ai plein d'autres erreurs.

Je ne comprends pas ce que je fais de mal.
J'aurais voulu télécharger directement tes correctifs mais je n'ai pas pu.

J'attends votre réponse, merci de m'aider.

Cordialement,
Lorenzo Cammilleri

2009/3/18 Julien Isorce <[hidden email]>

it's a bug in the original dshowaudiosrc,

as you can see in around line 360 of http://cgit.freedesktop.org/gstreamer/gst-plugins-bad/tree/sys/dshowsrcwrapper/gstdshowaudiosrc.c
there is no PROP_DEVICE_NAME case in the switch.
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;
  }
}
The fix is in the patch.

2009/3/18 <[hidden email]>

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'
