ffmpeg wont open my file

[boing]

I have a film that was windows media comprised of WMV video and WMAudioV2 audio, I have encoded the video to m2v with HC and now I want to get hold of the audio stream so I can the mulitplex

Now when I open ffmpeg and click browse the file is not listed even if I click 'all files'

Am I missing some kind of ffmpeg codec or plugin?

You're going to have to convert your source file to WAV first, before you can use ffmpeg. The must be a program to do that, just can't think of one at the moment.

Unless I am wrong, according to the ffmpeg documentation it supports wmaudiov2: http://ffmpeg.sourceforge.net/ffmpeg-doc.html#SEC20

Right you are, but FFMPEGGUI won't do that for you. You'll have to do it via command line.

If the file doesnt show up when you browse for it just type ** for the file name,then all files will be shown.

[Soopafresh]

OK, this looks like it works:

ffmpeg -i yourfile.wmv -vn -ar 48000 -ac 2 -acodec mp2 -ab 256 target.mp2


that will make 48K 256kbs mp2 file named 'Target.mp2'


I'm curious to hear if your resulting muxed MPEG has good audio sync. Please let us know.

Did it bollocks lol

I was gutted, the audio was out of sync right from the outset, starting at about half a second out then getting so bad I gave up trying to fathom how far out it was, I have no idea how it did that and as such I would be still at a loss even if I used some utility to offset the audio

In the end I Googled for some KVCD templates and used those to acheive a smaller VCD file, it was acceptable but still thats not the point is it?

The bastard beat me LOL
