Description Christophe Fergeau 2004-07-21 09:16:45 UTC

I've got a .mov file (its size is 1 MB, I can attach it if needed) which
triggers a crash in qtdemux with this backtrace:

qtdemux_parse_trak calls qtdemux_audio_caps with 
    stream->caps = qtdemux_audio_caps (qtdemux, fourcc, NULL, 0);
ie data is NULL, but then it does

    case GST_MAKE_FOURCC ('Q', 'D', 'M', '2'):
      /* FIXME: QDesign music version 2 (no constant) */
      return gst_caps_new_simple ("audio/x-qdm2",
          "framesize", G_TYPE_INT, QTDEMUX_GUINT32_GET (data + 52),
          "bitrate", G_TYPE_INT, QTDEMUX_GUINT32_GET (data + 40),
          "blocksize", G_TYPE_INT, QTDEMUX_GUINT32_GET (data + 44), NULL);

ie it assumes data is not NULL, hence the crash (at least this is my guess).

Comment 1 David Schleef 2004-07-22 21:50:08 UTC

Yes, please attach the file.

I fixed the actual crash in HEAD, but it probably won't play now.

Comment 2 Christophe Fergeau 2004-07-22 22:06:12 UTC

It's available from http://djdeath.dyndns.org/~djdeath/hop.mov actually. It's
only the 1MB of a 60MB file, I hope it's enough.

Comment 3 Ronald Bultje 2004-10-01 11:27:59 UTC

We don't have a QDM2 decoder. Otherwise, the crash is fixed. Video plays fine, also.
