Doh! # 24/02/2007: 0.01h - Blah, add something to -vf for now. >0.01g needs that. # 05/02/2007: 0.01g - Do scaling after the other filters, update -af comments # 04/05/2005: 0.01f - Fixed to work with MPlayer 1.0pre7 # 17/04/2005: 0.01e - Fixed bug with video filters not working (sorry) # 24/03/2005: 0.01d - Modifications by Joost Rohde: scaling # Also, defaults changed again. # 18/09/2004: 0.01c - Default video quality 5 (like it better) # 17/09/2004: 0.01b - Add user settable parameters (to the script) # ...just some things I've needed. # Perhaps some other modifications (don't remember) # 23/07/2004: 0.01a - Add detection of FAT/NTFS partitions. # Default video quality 3, default audio quality 2. # (thanks to Nilesh Bansal for suggestions) # Add detection of mplayer and encoder_example. # More verbose output. # 22/07/2004: 0.01 - initial release # User settable parameters # Extra parameters to video processing, without -vf prefix # eg. rotate=2 -> rotate picture left 90' # eq2=1.5,rotate=1 -> adjust gamma and rotate picture right 90' # hqdn3d -> reduce noise (increase compressibility) v_extra="eq2=1" # current version introduced a bug that you have to have something here... :) # Extra parameters to audio processing # eg. -af format=s16le -> convert audio to 16-bit (required by encoder) # -srate 44100 -> convert sample rate to 44.1kHz # (note that you need that "-af") a_extra="" # Extra parameters to the encoder # eg. -f 1000000 -F 66667 to fix some .wmv-problems (1000000/66667 -> 15fps) e_extra="" # ----------------------------------------------------- # FAT/NTFS detection if [ \( `df . --exclude-type=ntfs | wc -l` -lt 2 \) -o \( `df . --exclude-type=vfat | wc -l` -lt 2 \) ]; then echo Sorry, mkfifo \(which is used\) doesn\'t work on FAT/NTFS partitions. echo \(if you get this message by mistake, you can remove the \"FAT/NTFS detection\" echo from the script code\) echo exit fi # Check for MPlayer mplayer > /dev/null 2>&1 if [ $? -ne 0 ]; then echo You need mplayer!
