    i've built webcamoid from source (v5) and it insists on there being /usr/bin/lrelease-qt4 when my current Qt4 install has only /usr/bin/lrelease .. i fixed this with a symlink but why is this command name hardcoded instead of discovered?
    webcamoid is working fine with the webcam supplied with my Public Lab Desktop Spectrometry Kit ( http://www.publiclab.org/wiki/dsk ).
    i have a Creative Webcam Live!, too, but webcamoid crashes when i try to use it:

      Hi, lrelease path can be changed with the QMAKE_LRELEASE variable, see here.
      About the SIGFPE error, seems to be an error inside your FFmpeg libraries and not in Webcamoid. Anyway, let's assume that /dev/video0 is your non working webcam, does this command works for you?:

      ffplay -f video4linux2 -framerate 15 /dev/video0

    the ffplay test works fine with the webcam that crashes webcamoid.

      mmm... that's odd, Webcamoid shares much of its code with ffplay and ffmpeg, so this error must not happen. since the error is inside the avformat_find_stream_info() function I have no idea how to solve this right now.

      (stating the obvious) perhaps a wrong or missing parameter in webcamoid being passed along?

      These links relates this problem with pulseaudio, so maybe changing these lines to:

      "AudioOutput objectName='audioOutput' audioSystem='alsa',"
      "AudioInput objectName='mic' audioSystem='alsa' !"

      could solve the problem.

      Ok, let's take a more drastic approach, change this line to:

      /*if (avformat_find_stream_info(this->m_inputContext.data(), NULL) < 0)
      {
      this->m_inputContext.clear();
      emit this->error(QString("Cann't retrieve information from \"%1\" stream.").arg(this->location()));

      return false;
      }*/

      and recompile.

      These lines keep's my attention:

      Stream #0:0: Video: mjpeg, 640x480, -2147483 kb/s, 1000k tbn

      However, this is extending too much can you fill a report with all back traces and relevant information in the issues page?
