I'm running:
- Lubuntu 10.10
- MPlayer 2:1.0~rc4~try1.dsfg1-1ubuntu1+medibuntu1
- w32codecs 1:20110131-0.1medibuntu3
While trying to play a streaming rtsp clip with mplayer, I get an error message saying: Cannot find codec for audio format 0x55.
According to here, audio format 0x55 is "MPEG-1 Layer 3 (MP3)", and should be supported by l3codeca.acm. I do have l3codeca.acm in /usr/lib/codecs. However, when mplayer tries to load this codec, it says (see full log below):
Opening audio decoder: [acm] Win32/ACM decoders
Loading codec DLL: 'l3codeca.acm'
Loaded DLL driver l3codeca.acm at 212d000
ACM_Decoder: Unappropriate audio format
Could not load/initialize Win32/ACM audio codec (missing DLL file?).
It looks like this guy has the same issue, but he is playing a local file.
According to mplayer's Codec Status Table, this codec "conflicts with security kernel patches", but I'm not sure what that means.
Any ideas? I don't specifically need this to work in mplayer, I just want to be able to play it. However, vlc and openRTMP didn't work for me either (although I may not have been using openRTMP correctly).
Here's all the information mplayer spits out:
