[FFmpeg-user] is it possible to use two passes to generate segments?

[Giuliano Catrambone]

Hi,
     here follows all the console output:

ffmpeg -y -i ./maradona.wmv -vcodec libx264 -vprofile main -preset slow 
-b:v 300k -vf scale=480:360 -vbsf h264_mp4toannexb -flags -global_header 
-map 0 -f segment -segment_time 10 -segment_list ./index.m3u8 -threads 1 
-pass 1 -passlogfile /tmp/ff_maradona.ts -an /dev/null
