The actual version of mplayer (Build SVN-r28994-4.3.2) cannot handle certain Real-Audio streams using the COOK codec. Some days ago, Radio Ukraina rtsp://real.nrcu.gov.ua:7553/encoder/ru1channel.rm changed their streams from the SIPRO to the COOK codec and enhanced the bandwidth from 16k to 20k. Since then, I can here it with better quality from my hardware-internet radio (blik radio station) and also using RealPlayer GOLD 11, but mplayer fails. mplayer rtsp://real.nrcu.gov.ua:7553/encoder/ru1channel.rm gives the message demux_real: invalid chunksize! (0) The program keeps hanging until I stop it with Ctrl-C. The whole message output (sorry, it's compiled in German language) is: Konnte Namen für AF_INET6 nicht auflösen: real.nrcu.gov.ua Löse real.nrcu.gov.ua auf für AF_INET...

(Ende) The same error already occured with Mplayer SVN-r28519-4.3.2 (Feb 10, 2009) and even with version 1.0rc2-4.2.1 (Windows XP from the year 2007). What is quite strange is that MPlayer 0.90rc4-3.3 (suse-linux, 2003) can handle the stream data without problems. I can also dump the stream to file using the -dumpfile option of the actual mplayer, but I can play this recorded stream only with RealPlayer, not with mplayer. It looks like a bug to me, and I'd be glad if you could fix it.
