I converted a video from wmv to flv with mmpeg and the quality is terrible. I also get these:

Error while decoding stream #0.1  
[wmv2 @ 0x546b50]J-type picture is not supported338.8 bitrate= 279.7kbits/s

When I do the same conversion with On 2 Flix, it looks great.

Here is the line I am using to reencode:

/usr/bin/ffmpeg -pass2 -y -i test.wmv -ar 44100 -f flv test.flv

I tried using -sameq too. It looked good, but it was 55meg, the On 2 version was 15.

I’m using the version of ffmpeg my hosting company put on - I don’t know what version it is or how to update it. I like On 2 Flix, but I only have an old Windows version of it, and I’m trying to do the encoding server side on my linux machine.

Any ideas how to fix this?
