    Re: Help with getting a high quality video conversion into flv

    I can't even get the direct copy to convert.

    Is there a possibility that this could be related to the fact that the video was taken with a Japanese phone with Japanese characters?

    You might be best to try a more recent copy of FFmpeg, I used the most recent svn. My knowledge of asf (= zero) does not really qualify me to comment on why the headers are 'damaged' .

    Well, I guess this is why nothing I have on any of my boxes will play the video other than VLC (thank you VLC) ... lol. I'll see what I can do with SVN tonight. Perhaps this will turn into a ffmpeg bug report

    Building on Andrew's suggestion:
    Code:
    ffmpeg -i taiko_repaired.asf -ar 44100 -ac 1 -croptop 120 -cropbottom 120 -cropleft 160 -cropright 160 -b 384k taiko.flv
    flvtool2 -U taiko.flv
    This crops out the crowd and makes a 320x240 video. Adjust the bitrate as neccessary. I don't have much experience with flv, so I don't know how to optimize it beyond this, excluding playing around with qmin and qmax. I used svn FFmpeg.

    Thanks again for your help, I finally got around to installing svn version of ffmpeg so I could test this on my own. I'm beginning to think that this particular video might be particularly troublesome for some reason. After converting to flv, the sound timing is way off for this video.

    Other videos from the same phone seem to be converting much better though. Thank you.
