This is the output of idmedia on one of those fiels: |
| 11 |
|
| 12 |
ID_VIDEO_ID=0 |
| 13 |
ID_AUDIO_ID=0 |
| 14 |
ID_FILENAME=/home/buanzo/work/dd/DD_25_2005.MPG |

mplayer -identify -frames 0 -ao null -vo null -vc dummy "$@" 2>/dev/null | grep ID_ |
| 30 |
} |

The file is exactly 4566906464 |

This is a digital dump, probably really compressable, as I have already seen it. But they usually |
| 35 |
encode with wmv, which is, by no means, better. |
