ffmpeg unsupported codec prob

[loobyloo]

Hi there
I'm trying to get an mp3 from an flv using ffmpeg. I get the following error.

In another thread here someone recommended installing the libaveccodec 51 unstripped, which I have done, but the problem persists. Does anyone know how I can solve this?

I just took a quick look at the documentation for ffmpeg, and it looks to me like your command needs a slight tweak. I think if you put a "k" in the bitrate (-ab 320 should be -ab320k), it will work:

f
ffmpeg -i /home/cliff/Desktop/Sweden-Malena-La_Voix.flv -ac 2 -ar 44100 -ab 320k /home/cliff/Desktop/audio.mp3Give it a go and see if it works. Here is a link to the documentation I looked over:

http://ffmpeg.mplayerhq.hu/ffmpeg-doc.html

I hope this helps...

[loobyloo]

Thanks - I changed the bitrate but still get the same error.

Another puzzling thing is that mp3 is listed when I do a -formats on ffmpeg.

[Didius Falco]

I found another thread with a solution that worked for someone else. Try this:


ffmpeg -i /home/cliff/Desktop/Sweden-Malena-La_Voix.flv -acodec copy /home/cliff/Desktop/audio.mp3

[loobyloo]

Hi thanks - that at least converts the file but then Movie Player says "Could not determine type of stream."

I might give up to be honest! The world won't stop turning if I can't save this year's Swedish Eurovision song to my HD.

[Didius Falco]

I didn't even have ffmpeg installed, but I installed it and tried it out and it worked fine. I'm listening to the mp3 right now in Rhythmbox. Just loaded it in Movie Player too...are you sure you have all the codecs for Movie Player?

On Edit: here is a website with instructions on how to get the codecs:

http://www.ubuntugeek.com/install-mplayer-and-multimedia-codecs-libdvdcss2w32codecsw64codecs-in-ubuntu-810-intrepid-ibex.html

[loobyloo]

Really? That's odd. All my other mp3s work in both of those.

[Didius Falco]

is that flv on youtube? I'll download and try it out, just out of curiosity.

I'm learning as much as you are, maybe more. <G>

[loobyloo]

Yes, I saved the flv using the extension Mozilla extension UnPlug https://addons.mozilla.org/en-US/firefox/addon/2254

The (rather dire) song I'm trying to capture is at
http://www.youtube.com/watch?v=cnHr69JuiEk&feature=PlayList&p=29B0CA95AE3FF862&index=0&playnext=1

I do apologise in advance for the crimes against taste which this singer commits.

I downloaded MPlayer but it said I already had the most up to date version installed. When I go to open the file it says LAVF_header av_find_stream_info() failed. Which dfoesn't mean a huge amount :)

I googled that error, and it mostly seems to be caused by .avi and .flv files, not .mp3's.

Do you have the lame codec installed? It's in the multiverse repo. You can install it from the CLI by running:


sudo aptitude install lame

I downloaded that flv (I use DownloadHelper) and converted it and it's working in Movie Player, VLC and Rhythmbox.

I'm a little stumped if the lame codec doesn't help...

BTW, I laughed out loud at the "apology". <G>

You won't catch any flack from me, though. I'm originally from the land that spawned Vanilla Ice, so I'll just keep my stones in my own little glass house. ;)

[loobyloo]

Yes, I've got the latest lame.

It's a puzzle, but it's a nice day and I'm going for a walk before I get obssessed about this :)

[cotcot]

Try to install ffmpeg like this (http://ubuntuforums.org/showthread.php?t=786095). Ffmpeg from the repos does not have all codecs included because of license issues. The compiled version from the link is ok on that.

[loobyloo]

Thanks, that's very kind of you, but it's too much. It's not a crucial element to have ffmpeg running on my computer.

[FakeOutdoorsman]

Did you compile FFmpeg yourself? "SVN-r18532" seems way too recent for a repository FFmpeg. Here's a command that should work for SVN FFmpeg and will convert your source audio to mp3:

ffmpeg -i /home/cliff/Desktop/Sweden-Malena-La_Voix.flv -acodec libmp3lame -ab 192k /home/cliff/Desktop/audio.mp3

Didius Falco's suggestion (post 4) didn't work because your source video contains aac audio and that command is trying to force aac into a mp3 container. The command would work perfectly if the source audio is also mp3.

You also don't need the lame package for FFmpeg to encode to mp3. This is done through libmp3lame which is part of the libavcodec-unstripped-51 package (for users of the repository FFmpeg), or libmp3lame-dev for those who want to compile FFmpeg themselves. More details:

-------
So in the light of what you said, I checked if I had libavcodec-unstripped-51 or [b]libmp3lame-dev and I've got both.

[FakeOutdoorsman]

Where did you get this FFmpeg from? There is nothing listed under "configuration", so encoding with libmp3lame has not been enabled. This looks like a non-repository FFmpeg.

[loobyloo]

I think it was from http://www.ffmpeg.org/download.html#release
I don't know what an SVM is, but that's what I've got.

I look in Synamptic and it said I had ffmpeg, but from some of check update, which probably indicates an update of the "wrong" version that you mentioned.

So I reinstalled it from https://wiki.ubuntu.com/ffmpeg using the "Unstripped build of FFmpeg for Ubuntu 8.10 Intrepid". When I tried it again it came back with nothing under configuration and "unknown encoder libmp3lame.

What would be the best place to get ffmpeg from?

[FakeOutdoorsman]

Your computer is still using FFmpeg SVN, but it has not been configured to use any external encoders such as libmp3lame. If you installed it with checkinstall you can uninstall it via Synaptic, apt-get, or aptitude. If you simply installed it with "make install", navigate to your ffmpeg directory and then run:

sudo make uninstall
Now you can install FFmpeg from the repository:

sudo apt-get install ffmpeg

[loobyloo]

Thanks - it *was* from checkinstall.

I uninstalled it and reinstalled it from the repository.

I tried converting trhe file again and it came up with

Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 25.00 (25/1)

-----------
So I went to Synaptic and checked for libavcodec-unstripped-51, which was there.

Oh, dear...it's a good job I've got a bottle of red wine about a foot away!

Thanks for all your help so far. I don't know why I'm getting so obssessed about this damn thing.

worse.

[FakeOutdoorsman]

This should definitely not be this troublesome. You have the correct packages installed it seems, and the listed formats indicate that FFmpeg should be able to recognize and decode the aac and h264 streams in your flv, but it obviously is not doing so. I assume there may be a conflict with another package, but I am unsure. You could try telling FFmpeg what the audio is supposed to be:

ffmpeg -acodec libfaad -i /home/cliff/Desktop/Sweden-Malena-La_Voix.flv -acodec libmp3lame -ab 192k /home/cliff/Desktop/audio.mp3

[loobyloo]

Thank you very much - again, the audio appears to output correctly but when I go to play it Rhythmbox reports simply "Not playing" and SMPlayer does nothing at all. I'm just going to leave it now as I have a dissertation to write and children to look after.

Thanks to everyone on this thread for their patience and assistance over the last few days. I do appreciate it.

[poe]

Could it be, that you've got scratchbox installed? Maybe you use an alternative to /usr/bin/ffmpeg, just try this :-) helped me

Hi thanks Poe - I've lost interest in this now to be perfectly honest, but thanks for the suggestion.

In another thread here someone recommended installing the libaveccodec 51 unstripped, which I have done, but the problem persists. Does anyone know how I can solve this?

I installed the unstripped version 52 and it started working.
