Re: Wait is is a codec problem

Originally posted by cliff76
I finally stopped being stupid and downloaded the .mov file I was toying with and tried it in gmplayer instead of the plugin. I got the same results (video no sound) except this time there was an error popup. The popup said "can't find codec for audio format 0x324D4451". Now I searched google for the error (like any other law abiding Linux using citezen would do in this case) and found some references that said maybe mplayer needs to be compiled after the codecs are installed? I dunno. All I know is that I installed using synaptic over apt-get and that I couldn't install the codecs afterward. something the gui was complaining about mplayer-gui not being installed or installable. Now my question is how do I get mplayer to use the codecs that I downloaded? I installed them in both /usr/ lib/ and /usr/local/lib/. If I have to rebuild mplayer then what's the easiest way to do that? Remember I installed with apt-get. I'm running on Fedora core 3.
Well ya, you need to install them before you compile it. I think it says that somewhere in the documentation. I suggest uninstalling it if you can, then installing it again.

Just out of curiosity, did you try to set "ao=" to anything other than arts? I had a similar problem and had to set ao=alsa9, I assume because my system's running alsa.

I had the same problem with mplayer plugin on firefox. i could see the video on but could not hear the sound. Here is what i did to fix it.

download: all-20050115.tar.bz2
extract all-20050115.tar.bz2 to /usr/lib/
must have root privileges to do that.
name the folder "all-20050115" to win32
so now you must have a folder /usr/lib/win32 with all the codecs necessary for mplayer.

now try watching the movie again and see if it works. If it doesn't let me know.

My problem was something to do with oss. I switched to alsa and sound returned. I also configured mplayer to use alsa.

I had the problem with no sound and I followed the steps from the user morneo and finally got sound.

But the problem is now that I can't rewind or fast-forward (even when the next frames are already buffered).

Figured it out a week ago! I was putting the codecs in the wrong place! I had them in /usr/lib/codecs and it appears that all multimedia apps look for them under /usr/lib/win32. So What I did was I created a symbolic link to the codecs folder under /usr/lib and called it win32 to replicate the expected file structure. Why didn't I just move the files? Well I was thinking that maybe somewhere down the road something would be looking under /usr/lib/codecs and I wanted to make sure it could still be found there.

I'm still having misc. problems with Xmms audio output driver. I choose the aRTs output driver and I get sound for a while. I then go home leaving my computer on but shutting down Xmms and return the next day where the aRTs audio driver no longer produces sound. I switch to OSS and I get sound! strange and I still don't understand the way sound works. Maybe someone can clear this for me?
