Trying to convert from flv to mp4 (for iPod) using mencoder.
 
I used the latest 1.0rc2 MPlayer script from SlackBuilds.org. I also have a faac package installed from SBo as well.

Here's the command I'm running to convert the flv file into an mp4 and the output I get:

Code:

Have you tried using 'ffmpeg' for the conversion instead ? I've found mencoder to produce horrible results for converting most things.

ffmpeg works without a cinch.

I think you need to use -faacopts not -lavcopts to use the aac codec.

Please don't throw out sweeping comments like that without at least giving some examples. mencoder works very well for many things. It even uses ffmpeg codecs (among others) as well, so if you are converting with the same codecs and the same settings I don't see how the quality would be different.

It's different because it's harder to get the settings right ... if not impossible ?

I tried it - it didn't work.
