On the Acer Revo and other similar devices, using .bmp images for your backdrops can really improve performance, especially in skins like Aeon.

I wrote a little script to automatically do this and just thought I would share it since I didn't find much when I searched for something like this.

You can put this in a file in /etc/cron.hourly , just don't forget to chmod +x the file after you create it. Oh, and don't use a file name with a "." in it for your script or run-parts (cron) won't pick it up.

Code:

#!/bin/bash

DIRS[1]=/home/xbmc/.xbmc/userdata/Thumbnails/Music/Fanart
DIRS[2]=/home/xbmc/.xbmc/userdata/Thumbnails/Video/Fanart
DIRS[3]=/home/xbmc/.xbmc/media/backdrops/pictures
DIRS[4]=/home/xbmc/.xbmc/media/backdrops/settings

for DIR in ${DIRS[@]}; do
  (IFS=$'\n'
  for i in `find $DIR -type f | fgrep -e bmp -e BMP -v`; do
    FILENAME=`basename $i`
    FILENAME_NOEXT=`echo $FILENAME | cut -d'.' -f1`
    convert $i $DIR/$FILENAME_NOEXT.bmp
    rm -f $i
  done
  )
done

This requires Imagemagick to do the conversion, so make sure you have that installed first.

nevermind, sorry

Better yet, use dds files.

Code:

#!/bin/bash

DIRS[1]=/home/xbmc/.xbmc/userdata/Thumbnails/Music/Fanart
DIRS[2]=/home/xbmc/.xbmc/userdata/Thumbnails/Video/Fanart

for DIR in ${DIRS[@]}; do
        for f in `find $DIR -type f | grep -e ".bmp" -i -v`; do
                FILENAME=${f##*/};
                BASE=${FILENAME%%.*}
                NEW_FILE=$DIR/$BASE.bmp;
                if [ ! -e $NEW_FILE ]; then
                        CMD="convert $f $NEW_FILE";
                        eval $CMD;
                        rm -rf $f;
                fi
        done
done

Mine, if the file already exists, it doesn't do anything (no use wasting the CPU every hour)

My script won't do anything if the file has already been converted either because the converted files have been renamed with .bmp extension. The script only finds and acts on non-bmp files.

Duh... good call. Mine does too.

For those that are wondering "well what sort of speed up":

Here is a before:

Code:

for one show's fanart.

Here's my latest script:

Code:

#!/bin/bash

DIRS[1]=/home/xbmc/.xbmc/userdata/Thumbnails
temp="/tmp/0.$RANDOM.bmp"
for DIR in ${DIRS[@]}; do
    for f in `find $DIR -type f -name *.tbn`; do
        file $f | grep "PC bitmap" > /dev/null
        if [ $? -ne 0 ];then
            echo "converting $f";
            CMD="convert \"$f\" \"$temp\""
            CMD2="mv \"$temp\" \"$f\""
            eval $CMD;
            eval $CMD2;
        else
            echo "$f already converted."
        fi
    done
done

I kept the tbn extension because some where I read that's where it looks first.
