Hello,
Today I compiled 64-bit binaries for MPlayer and mencoder on a very recent OpenSolaris box
and although the video output is correct, the audio ioutput is not always OK. In particular, when
playing an MP3 file the audio output is distorted. However when I use the -ac ffmp3 switch,
the audio output is as it should be. Here is what I get on my computer's screen:
$ ./mplayer song.mp3
MPlayer SVN-r30956-4.3.2 (C) 2000-2010 MPlayer Team

Interestingly, the same happened with AC3 audio with binaries produced from SVN-r30145.
Now, the internal a52 library is not compiled:
$ ./mplayer /extra/download/videos/tha_tsimpisw.mkv

Any ideas what might be the solution to this problem?

PS In addition, I had to apply the following two patches in order to compile the source code:
