------- Comment #26 from Lutz Mueller  2007-01-01 18:21 UTC -------
Our ways crossed - I continued to work on the driver and renamed it
gstrealvideodec - in order to be able to provide in the same directory the
audio decoder (gstrealaudiodec). I can't see the work you checked in CVS yet
(anonymous access). What should I do? Can you still rename the decoder or
should I write the audio decoder in another directory?

Regarding the default paths: The debian package w32codecs installs the codecs
in /usr/lib/win32. The default paths should probably be determined by the
configure script.

There is one issue I fixed today in the video decoder: Right after the call to
dec->init in the setcaps function, I've hardcoded some bits. You need to
replace the code by the code below:

  res = dec->init (&data, &dec->context);
  if (res)
    goto could_not_initialize;

  if ((v = gst_structure_get_value (s, "codec_data"))) {
    GstBuffer *buf = g_value_peek_pointer (v);
    guint32 *msg = g_new0 (guint32, 11 + GST_BUFFER_SIZE (buf));
    guint i;

    if (!msg)
      goto could_not_allocate;
    msg[ 0] = 0x24;
    msg[ 1] = 1 + ((dec->subformat >> 16) & 7);
    msg[ 2] = (guint32) &msg[9];
    msg[ 9] = dec->width;
    msg[10] = dec->height;
    for (i = 0; i < GST_BUFFER_SIZE (buf); i++)
      msg[i + 11] = 4 * GST_BUFFER_DATA (buf)[i];
    res = dec->custom_message (msg, dec->context);
    g_free (msg);
    if (res)
      goto could_not_send_message;
  }

(...)

could_not_allocate:
  dlclose (dec->handle);
  dec->handle = NULL;
  GST_DEBUG_OBJECT (dec, "Could not allocate memory.");
  return FALSE;
