RealAudio problem

[gkulcsar@…]

I've downloaded a file from www.radio.hu.
It is in RealAudio format, with the extension .rm.
When I try to open it with mplayer (no options), it crashes the ac3 (!) decoder.
When I remove the ac3 decoder (-ac -ac3), it says:

REAL file format detected.

Cannot find codec for audio format 0x74656E64.
Read DOCS/HTML/en/codecs.html!

I checked this magic number, and it identifies ac3 files (that's why mplayer
tried to open it with its ac3 decoder...).

The file plays without problems with the original RealPlayer.
What's wrong?

OK, here is the normal output, without any options:

• MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
• MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc version. If you think it's MPlayer's fault, please read DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and won't help unless you provide this information when reporting a possible bug.

Can you give the exact url for that file (or upload it on mphq)?
The use of ac3 could be right, real dnet is byte-swapped ac3.

Works fine for me with latest CVS under linux. What version are you using (where
did you get it from)? Does it work with -ao win32?

[gkulcsar@…]

-ao win32 makes no difference.
The file I downloaded is called MPlayer-mingw32-1.0pre6.zip (downloaded from
mplayerhq.hu).
Here is the first few lines of the player output:

Please test if it works with
​http://www.mplayerhq.hu/MPlayer/releases/win32-beta/MPlayer-mingw32-dev-CVS-050227.zip
If it still doesn't work you should give the full output when using mplayer with -v

I've also tried it again with -ao win32, but got the same result.

Checked again.
Now (as of 14-12-2005) it works with the latest CVS snapshot build for Windows!

Resolving as WORKSFORME, the reporter says the problem is gone.
