Sipro audio.
That's not the first time i heard about problems with this codec, but  
in your sample the sound is garbled from the beginning, and that can be  
helpful in debugging the problem.

Will have a look at this too, but it won't be an easy job.


Regarding the other file, i think there are also problems in other   
videos where frame size changes during playback.

If somebody is interested, please have a look at  
http://www.mplayerhq.hu/~rtognimp/size_change_mpeg/ and check how those  
files behave for you (i think any cat'd mpeg files with different size  
will do).

The attached patch (experimental!) detects the size change in the Real  
file, and should also reinit mplayer to handle it. But it doesn't work.
And it also discard a frame at size change (and sig11 if frame changes  
to a bigger size), but those are minor problems :)
If you replace the #if 1 in decode() with #if 0, you get solid filled  
image instead of video dat, to show that the problem is not codec  
related.

So i still have to figure out if i'm doing something wrong or if the  
working case is just a lucky one.

Ciao,
 Roberto
