Hi all!

Found this message on xine-devel, so i performed some test

All test with new codecs were done with dll from real player 10 beta  
for win (i was too lazy to register on Helix site) (installation fails  
in wine, but you can find everything uncompressed in /tmp !)

Video:
rv10 samples played ok with linux RV9 dll
BTW they included a single decoder for both RV8 and RV9 in realplayer10  
(drvc.dll), so the two formats should be very similar.

Audio:
raac files fail with faad (simply added raac 4cc to faad, no other test  
performed)
Trying to use raac.dll doesn't work: first i got an error because of  
missing symbol (RASetFlavor), after removing the check MPlayer  
segfaults in wraInitDecoder (Opencodec is successful).

5.1 file works ok if i replace our cook codec with cook.dll (tested on  
a 2 speaker system). The codec reports realaudio 10. Didn't test it on  
old cook files, but it have to be backward compatible.

raac files have audio section version 5 (ra5), but they have the first  
fourcc as vbrs instead of the usual genr.

Streaming these files gives me two unknown rdt values at the end  
(probably this is not specific of these files).

The lossless file doesn't even starts: MPlayer finds 3 unsupported  
streams type, no audio and no video. There is no ra block in the file.

That's all for now.
Someone familiar with AAC please take a look at raac files, if it's AAC  
it shouldn't be too hard to parse it to something faad can decode.

Ciao,
 Roberto
