Convert flv to mpeg2

[ronnielsen1]

I'm trying to change some flv videos to be able to play on a dvd player and after numerous attempts and googling I was able to play a lower quality dvd. I was trying to use dvdauthor for my latest attempt but it insists on mpeg2 files and not the avi or mpq I'm ending up with. Does anyone have any advice?

A suggestion from a discussion at the Puppy Linux forums. One of the posts suggests the following ffmpeg command for converting flv to mpeg-2:

ffmpeg -i file.flv -ab 128 -ar 44100 -b 500 -ac 2 -s 320x240 file.mpg

If commandline is not your thing, there is a Linux GUI for Mencoder: AutoMen for Linux. I think it's Free software, but I'm not sure. According to this review, it supports flv

If you get really stuck, there's a freeware program called Mediacoder, which mostly works with WINE. Apparently, it converts from flv to mpeg-2.

run this with wine. It works amazingly!

[EDIT]

I should really learn to read previous posts completely ^_^

Shouldn't the resolution be increased to 720 x 480?

[ronnielsen1]

Ok, I was able to change the videos but is there a way to increase resolution so the dvd has a good picture?

The target option in ffmpeg will automatically set the other options (frame size, bitrate, codecs, buffer sizes) and make an appropriate output:

ffmpeg -i input.flv -target dvd output.mpg

[ronnielsen1]

ffmpeg -i input.flv -target dvd output.mpg

This works great on some but on others it returns an error similar to:

ffmpeg -i Walkin_down_the_road.flv -target dvd WalkingDownTheRoad.mpg

Could not determine norm (PAL/NTSC/NTSC-Film) for target.
Please prefix target with "pal-", "ntsc-" or "film-",

I've experimented with a few ntsc options and I didn't guess right.
I'm also wondering. When playing the videos in VLC they're still not real good video (yes, it does change it to dvd resolution) Is there a way to get a better picture or to have a smaller size video (Not take up the whole tv) in order to have a better picture?

Try this:

ffmpeg -i input.flv -target ntsc-dvd -padtop 120 -padbottom 120 -padleft 180 -padright 180 -s 360x240 output.mpg

It declares a frame rate and adds black padding to cover the rest of the screen.
