FFMPeg unsupported codecs problem

[alexandernst]

I'm trying to convert a flv video to mp3 but I'm getting an unsupported codecs error message.
Why is that?
Thanks

Re: FFMPeg unsupported codecs problem

How are you trying to convert - what GUI application or CLI command - and what is the exact error message?

Re: FFMPeg unsupported codecs problem

ffmpeg -i video.flv audio.mp3

And I get "Unsupported codec for output stream #0.0"

This is ffmpeg version output:

Re: FFMPeg unsupported codecs problem

I just used winff .........the GUI for ffmpeg to convert a .flv to mp3 and it did ok even though the konsole output sead it faled press eney key to continue.

the resalting Mp3 is good though................just a FYI if you use firefox and do this sort of thing a lot you mite want to try the firefox extenshon downloadhelper it will dl stuff from youtub and the like and do the converting to.

Re: FFMPeg unsupported codecs problem

I'm not a noob :S
I wrote this post because there is apperantly an error with ffmpeg's package.

pd: And I already know about that plugin for firefox. Thanks anyways

Re: FFMPeg unsupported codecs problem

Who said you were? From your OP:

ffmpeg -i video.flv audio.mp3

My read of the link I provided would indicate that your CLI above is syntactically incorrect. You are trying to extract the audio only from a video file.

Re: FFMPeg unsupported codecs problem

Google would have returned me the same thing...

And, FYI, -vn is not necesary as I'm trying to convert to audio only format, so there is no place for errors, +I have been converting videos this way since ever. But ffmpeg broke when I did the upgrade from 9.04 to 9.10, and that's why I sad that there is a problem with the package.

Re: FFMPeg unsupported codecs problem

Yes I do. I also have libavcodec52 so it should work, but it doesn't.

this is strang as I allso uped to 9.10 from 9.04 did you reenabel the medeabuntu repo as the up grade will coment it out # as part of the proses mabey uncoment it and do the update dst-upgrade thing and see if it gets fixed?

Re: FFMPeg unsupported codecs problem

Yes, I already did that too. I enabled medibuntu, installed ffmpeg, did dist-upgrade, etc etc etc.
Any other ideas?

Re: FFMPeg unsupported codecs problem

Error:

Unsupported codec for output stream #0.0

With the ffmpeg and with the mp3 => Bug:384451 Unsupported codec for output stream #0.0:

so whats the problem then? Main does not ship any mp3 encoder, it can
only be found in multiverse. That's where the unstripped version is so
it can be built against it.

With the Karmic:
> Package: libavcodec-unstripped-52

ffmpeg utility library - transitional package

This package can be safely removed if no other packages depend on this

The libavcodec-unstripped-52 (Karmic) will install > Package: libavcodec-extra-52:

ffmpeg codec library

This is the codec library from the ffmpeg project. It supports most existing encoding formats (MPEG, DivX, MPEG4, AC3, DV...).

This package contains a unrestricted version of the libavcodec shared object that should only be used by Debian packages.

Have you tried it ?
