Re:Re: [Linphone-developers] the video under windows is not stable

[zengengzhuo]

I've successfully compiled mediastream2 in Linphone 3.1 the other day and via winvideods.c the DirectShow works well. thanks～

But there is another problem, the mediaStack can't set the microphone and the speaker's volumes.

Could anyone help me ? Thanks.

=====================================================================

static void winsnddscard_set_level(MSSndCard *card, MSSndCardMixerElem e, int percent){
    MMRESULT mr = MMSYSERR_NOERROR;
    DWORD dwVolume = 0xFFFF;
    dwVolume = ((0xFFFF) * percent) / 100;

 switch(e){
  case MS_SND_CARD_MASTER:
            /*mr = waveOutSetVolume(d->waveoutdev, dwVolume); */
         if (mr != MMSYSERR_NOERROR)
         {
                ms_warning("Failed to set master volume. (waveOutSetVolume:0x%i)", mr);
                return;
         }
        break;
        case MS_SND_CARD_CAPTURE:
  break;
  case MS_SND_CARD_PLAYBACK:
  break;
        default:
   ms_warning("winsndds_card_set_level: unsupported command.");
 }
}
