This almost works with wine 6.0-rc5, except that it crashes, apparently due to
this:

00d8:err:gstreamer:gstdecoder_init_gst Failed to play stream.
0138:err:gstreamer:watch_bus avisubtitle0: Could not decode stream.
0138:err:gstreamer:watch_bus ../gst/avi/gstavisubtitle.c(235):
gst_avi_subtitle_parse_gab2_chunk ():
/GstBin:bin0/GstDecodeBin:decodebin0/GstAviSubtitle:avisubtitle0:
Wrong magic word

Weirdly, it works fine with gst-play-1.0, so I don't know why it breaks with
winegstreamer.
