Converting Flash to AVI

[Kreuger]

Following this guide I tried to encode a flash file off youtube (.flv) into an avi file. It didn't work. I tried this:

mencoder episode.flv -ofps 15 -vf scale=300:-2 -oac lavc -ovc lavc -lavcopts vcodec=msmpeg4v2:acodec=mp3:abitrate=64 -o episode2.avi

but ithis is what happened:

Audio LAVC, couldn't find encoder for codec mp3

So I guess it can't find an mp3 encoder but I've converted files to mp3 (from flac) via LAME before. Why isn't it working?

Edit:

I just tried it with ffmpeg as well using

ffmpeg -i episode.flv -s 320x240 -r 15.00 -b 300 -f avi -vcodec xvid -acodec mp3 -ab 96 episode.avi

and it created the file but it was 0bytes.

what distribution are you using? You probably need to install the mp3 encoder lame or something, varies on the distro. If ubuntu, install the stuff here: https://help.ubuntu.com/community/RestrictedFormats

[Kreuger]

I have lame. I used it before to convert songs, I already said that.

or you can just convert flash to video using programs such as Flash to Video Encoder Pro, i think it's more convenient, just in one step-and you see the result!

Which is a closed-source, proprietary, paid for Windows app...

[markwolfe Veteran]

^^^ Does it run in wine? :whistle: :rofl:

[Kreuger]

Not for me and it's only a trial so it's rather useless. There's now a script for Konqueror that's supposed to do it, but I had problems with it.

[Rob2687]

Do mencoder -oac help and it will list the audio codecs available.

This seems to work for me..

mencoder test.flv -oac mp3lame -ovc xvid --xvidencopts pass=2:bitrate=-1 -o test.avi

MPlayer was compiled without libmp3lame support.

--xvidencopts is not an MEncoder option

Exiting... (error parsing command line)

I installed it via Synaptic. I guess I'll have to compile it myself? But what about the xvidencopts is not an mencoder option? Is that a typo on your part?

[Rob2687]

Yes...Remove the extra '-'

So just -xvidencopts pass=2:bitrate=-1

You can change pass to 1 or remove it the pass= option...I don't think there will be much difference in video quality.

Are you running Ubuntu? The SVN mplayer builds are kinda broken for me lately. I think since RC1. I'm trying to get the 1.0pre8 builds to compile. Unless there is someway to compile mencoder by itself...

[Kreuger]

Yeah well Kubuntu. maybe I'll just grab the source (not svn but the stable) and do it that way. I've never been able to get it to compile. Always had troubles with it so I think it's best to go with the stable.

[Rob2687]

I get the same brokeness in trunk and the RC1 release. I've narrowed the problem down to an issue with the video outputs when using gmplayer. Not sure if it's mplayer or something else that's causing it. (Probably that piece of crap fglrx or something) Only the X11 output + software scale works right.

Anyways...What problems did you have compiling it before?

[Kreuger]

I don't recall but it seems to have worked fine now. I still get the error about xvidencopts.

Edit: I'm going to try to recompile it with xvid flags shown here

Edit 2: When I tried to compile, it wouldn't let me use

Couldn't find video filter 'xvid'.

Edit 3: I found a site that suggested a frontend called encode2mpeg and using this command

encode2mpeg file.flv -o file.avi -ffourcc DIVX -avionly -encode 3 -usesbr 2

I was able to convert it to avi but it had bad quality sound. Just got to figure out the best way to use it. Edited November 4, 2006 by Kreuger

[Rob2687]

Well you can also get libxvidcore4-dev in from multiverse. Configure mplayer --enable-xvid and make sure it's listed under the enabled codecs.

[Kreuger]

I have it installed. I enabled it when I compiled and it shows in the list of codecs so I dont know what's wrong with it.

[Rob2687]

I'm not sure why it would be doing that...

Did you uninstall the old mplayer and all that before installing your compiled version?

[Kreuger]

Nah I left it. I think it overwrote it.

[gasp]

for converting flash I can offer Macvide FlashVideo Converter...but this prog for mac...
