I convert through Mencoder it is working fine but I am having real poor quality for wmv to flv. I tried changing $cmd_all = $cmd_mencoder; to $cmd_all = $cmd_ffmpeg; and I am getting this error. Any help on this ?
Code:
CONVERT COMMAND: /usr/bin/ffmpeg -i /home/me/public_html/mysite/video/abc.wmv -acodec libmp3lame -ar 22050 -ab 32 -f flv -b 700 /home/me/public_html/mysite/flvideo/1205406862499217463.flv
