help extracting audio

[flashcabaja64]

do i need any codecs for goldwave to read rmvb files. if there is any can you tell me???

i want to extract the audio out of the rmvb file to wav.

Well assuming that it renders via dshow you would need real codecs and Gabest's real media filter.

If I wanted to decode a rmvb's audio to wav though I would just use mplayer.

haha yea i dled mplayer but i dont know how to use it. can you possibly guide me through the process of making the wav file using mplayer?

also where can i dl those codecs

[Baldrick]

Start->run or use the command prompt and type:
"c:\mplayer.exe" -ao pcm:file=output.wav "c:\input.rmbv"

Replace c:\ to the location of the files.

heres the error i got

where do i dl the codecs at?

Are you sure, you got a Windows executable? AFAIK .so is a Unix/Linux extension for shared object.

The above command will run realtime by the way. You need to add -vo null -vc dummy, that way it will run much faster. Also you could have just searched as I and probably others have posted the info numerous times already.

As for the error, it also shows that it fails to load the dll equv's of the .so's. You need to download the windows real codecs from the mplayer site and place them in your codecs dir. I think I also posted this info somewhere around here before.

If your rmvb file had used aac audio instead of cook (I thought most did) then it should have worked without the need for real's codecs.

I'd post a direct link to the codecs, however the mplayer site seems to be down right now.

srry i dont understand im so confused.

[Dragonsf]

Obviously the program needs some dlls which aren't avaiable on your computer. Mplayer seems to be a Linux development and needs those .so file (Unix equivalent to .dll) for execution. Maybe you got the wrong files (Linux .so don't work with Win) or you got no file at all. Is cook.so on your machine?

[flashcabaja64]

kool. i got it. i searched and i found my problem. i just needed to install real alternative. THANKS ANWAYS

[celtic_druid]

You don't need the .so files under windows, just the dll's which can be downloaded from the mplayer site (if it is up), no need for real alt. In fact you don't even need all of the dll's just the one in the error. With out -vo null -vc dummy you would also need dll(s) for the video.

ok i went to the mplayer site and dled the codec files. which folder do i put them all in????

[celtic_druid]

In the codecs directory. Should also read them from your system dir or probably anywhere in your path.

[flashcabaja64]

i dont know wheres the codec direcory. do i have to make one???

[celtic_druid]

In all my packages there is an empty dir "codecs". Not sure what you have though.

[flashcabaja64]

i dont follow. what do you mean by "all my packages".

[celtic_druid]

Package as in mplayer/mencoder compiles with conf, etc. files all "packaged" in an archive (7-zip in my case).

[flashcabaja64]

ok i installed the codecs but when i type that thingy in the command prompt it tells me that the cook.so file and some other file (i forgot) couldnt load. i know those files are for linux but will that interrupt my encoding? also where does the audio goto after itz converted?

also in your previous post you said to add -vo null -vc dummy, where am i suppose to add that?
