video - Converting Real Media with ffmpeg -
i have number of old crusty real media files need convert , hoping write script batch process them. i'm able real media -> avi conversion ffmpegx, when try replicate conversion ffmpeg, errors out like:
[avi @ 0x10084fa00] large number of skipped frames 117425 > 60000 it may have funky format of these real media files:

including ffmpeg command (thank @mondain teaching me stream mapping!) , output:

it appear file contains several streams , when working ffmpeg, need select ones want convert. 1 assume want audio / video pair @ highest quality within file. here how use "map" option target streams: http://trac.ffmpeg.org/wiki/how%20to%20use%20-map%20option
if had file use command:
ffmpeg -i [real-input-file] \ -map 0:8 -map 0:7 \ -c:v libx264 \ -c:a libfaac -b:a 32k \ output.mkv
