[MPlayer-dev-eng] Odd lockup at end of file when playing a realmedia rtsp stream using liba52 codec

I was playing a short length streaming realmedia audio sample on rtsp URL
mplayer -cache 50 rtsp://real.cbsig.net/g2demand/entertainmment/
mini/lateshow/records/goofy.rm
there was a lockup at the end where I had to end mplayer with CTRL-C
I looked at trying to fix the issue and
traced lockup to while loop inside libmpcodecs/ad_liba52.c
a52_fillbuff(sh_audio_t *sh_audio) {
...
while(sh_audio->a_in_buffer_len<8){
int c=demux_getc(sh_audio->ds);
if(c<0) return -1; /* EOF*/
sh_audio->a_in_buffer[sh_audio->a_in_buffer_len++]=c;
}
...
}
note demux_getc is defined in libmpdemux/demuxer.h
Here is the output using verbose loging
could someone more knowledgeable help with fixing this?
