Get on the server with the flv files and use:

ffmpeg -i input.flv -sameq -ar 22050 output.mp4

Replace "input.flv" with the source filename and "output.mp4" with your
desired output file name. That should do it.

I tried that earlier but don't no how to deal with the errors.

Try rerunning the command but include "-strict experimental" (line
below may be wrapped due to mail message width...should be all on one
line):

ffmpeg -strict experimental -i 3852374-xxxx_bashing_.flv -sameq -ar
22050 output.mp4

I thought perhaps the problem was with the original file and so
tried a different one:

I am using ffmpeg installed via yum a few days ago, should be the
latest, greatest. I've Googled it extensively, tried whatever I
found much like a rat in a mze ...

Does the solution require using ffmpeg?

I use "handbrake" a gui tool for all my conversion needs and it works great.

It isn't a Fedora download, and you have to use the download from their site for F16 but it works fine in F17. Just an option if you care to explore.

OK, good, I just converted the Flash file I last tried to do with
ffmpeg using handbrake and VLC plays it full screen. It works for me
... I'll give it a better work out tomorrow. End of day here, that's
several problems solved today!

Thanks Ed,

Bob
