    Hello guys,

    I've recently used FFMPEG to convert videos to FLV format. however, upon conversion, the video looks really awful. I'm not sure how to describe it since I'm not an expert with video encoding/decoding. If you want to see what I mean, please go to the URL below:

    Output: (FLV format)
    http://209.123.16.37/video_watch.php?movie=616

    Input: (WMV format)
    http://209.123.16.37/g/smart.wmv

    This is the command that I used:

    FFMPEG -i source.wmv -acodec mp3 -ar 22050 -ab 32 -b 200 -r 15 -y -vcodec flv -output.flv

    I'm not sure what's wrong with this but if you'll check out other videos in the site, some of them works fine while some still does not.

    Any help would be very very very much appreciated.

    Thank you.

    The command is correct.

    Your source contains j-type pictures which are not supported and cannot be decoded by ffmpeg.

    I can't handle hearing that "dude" say "They were DEEE-coys" any more.

    mencoder file.wmv -srate 22050 -oac mp3lame -lameopts cbr:br=56:mode=3 -ovc raw -o "raw.avi" -mc 0

    ffmpeg -i raw.avi -vcodec flv -b 500 -r 15 -acodec copy -y test.flv

    flv.zip

    alright, I'm not sure what to do here. I guess there might be a problem with FFMPEG on our server. (Correct me if i'm wrong here)

    I've applied the value 'copy' for the argument acodec (-acodec copy) but when I do this, no file is being generated. I'm not sure how to enable error logging since its on a remote machine and there's no way for me to access it. I'll need to contact our Admin and inform him about this.

    Thanks for the assistance again. Will write back if I found a way to check the error log.
