"0xF0 opcode seen in SMC chunk"

[torbjorn.e.andersson@…]

I realize that this is not a complete bug report - I don't have Internet access
to my Linux box, so all I currently have is what I brought to this computer -
but perhaps it will be enough as the problem does not appear to be
machine-specific. If not, I can add more information later.

At least two of the QuickTime movies on ​http://www.lysator.liu.se/juggling/ fail
to render correctly in MPlayer 1.0pre7:

​http://www.lysator.liu.se/juggling/video/MichaelMenes1986.mov

It opens a window, and I believe it's the right size, but all it shows is
semi-random jumble black-and-white patterns. The sound plays fine, but I believe
that part is done by one of the Windows codecs.

I have tried the "Gatto" movie both on my Linux box and on a Windows box with
the experimental MinGW version of MPlayer. The movie renders fine (albeit
without sound) in xine, which is encouraging since I believe they use the same
underlying library for this codec.

Here are the messages I get during playback:

[r_togni@…]

Both files contain a video tracks encoded with two different codecs: a single
frame using "smc " and the rest of the tracks using "SVQ1" (use mplayer -v to
get all the details).
Mplayer does not support this yet, and prints the "MOV: WARNING: Variable FOURCC
detected!?" message.

Works with default lavf demuxer, also works with -vc +ffsvq1.
Native mov demuxer bugs will no longer be fixed.
