Yep, you're right about that - a FLV that's been generated server side (like with the Publisher.swf demo) has audio that makes FFMpeg die. It won't even just copy it (or at least I haven't managed to get it to yet) so doing anything that requires transition from one format to another with something recorded serverside is pretty much out of the question at the moment (until such time as we have tools to handle that nelly moser codec).
But if the FLV was encoded with some other tool that used MPEG Layer III (MP3) as the audio format, then it's good to go - works nicely to convert between formats. Has anyone tampered with forcing the audio recording "flavor" from within their application - or is that already a beaten path that goes no where? -N On Thu, 3 May 2007, Jake Hilton wrote: > But would the flv to avi preserve the audio?
