1) This is the ffmpeg list, maybe you want
http://lists.mplayerhq.hu/mailman/listinfo/mencoder-users

2) With a filter you have to reencode, and you don't specify good
codecs for iphone etc. etc.

In ffmpeg there is the transpose filter, so something like this
should get you started:

ffmpeg -i $in-landscape -vf transpose=1,scale=360:480 \
       -c:v libx264 -preset fast -crf 22 \
       -c:a libfaac -b:a 128k out-portrait.mp4

qt-faststart out-portrait.mp4 out.mp4

> then video will rotate 90 degree successful and also video will upload on
> Amazon S3 and all the information will store in the database table.that all
> stuff work completely.but when user want to see the video on site then it
> will show on error like:200,paly stream not found clip[]..full URL of
> video.. 
> 
> If i don't rotate the video and upload video from app then it will open
> normally with out any error like above.. 

This sounds more like a permissions (not public) or metadata
(wrong content-type) problem in the s3 bucket for the files in
question. Double check in the aws console.
