php - using FFMPEG to convert to MP4 with maximum browsers compatibilty -

i'm converting wmv flv using ffmpeg, , problem flv videos big! 15 minutes video's size ranges between 150mb , 1gb! i'm using next ffmpeg command convert , split wmv videos : nohup nice -1 ffmpeg -y -ss 00:00:00 -t 00:15:00 -async 1 -i input.wmv -acodec libmp3lame output.flv , i've tried converting mp4 before , video size much smaller flv video. questions are:

would mp4 videos have compatibility issues browsers? would work on iphone, ipad? (i know flv videos doesn't work on iphones or ipads) what best ffmpeg command convert mp4 without losing quality of video?

a few points...

video size has bit rate, dimension, , codec. not have container. you can expect 15 minutes of video large, assuming want more postage stamp stamp viewing area. normal. any time re-compress something, going lose quality. there no way around this. might able maintain quality recompressing @ higher bitrate, defeats trying accomplish.

bottom line, unless need to, don't it. encode videos @ appropriate bitrate begin with.
