Scripts: Converting media to Android G1

[the3kgt2]

I have a home media center and wanted to be able to sync all recorded tv, podcasts, and pictures to my Android G1. This could be used for other phones and media players too. They can be modified for better resolution and sound quality, but I suggest leaving them where they are...these settings are perfect for the G1. Change the folder directories to suit your system. Put these scripts in your crontab.

Converting recorded TV and podcasts:

#!/bin/bash
# Convert video files to mp4 for the Android G1
#
# Warning: different folder hierarchy may cause problems
#
# Compile ffmpeg with these options:
# ./configure --enable-gpl  --enable-postproc --enable-nonfree --enable-postproc --enable-libfaad --enable-swscale --enable-avfilter --enable-pthreads --enable-libxvid --enable-libx264 --enable-libmp3lame --enable-libdc1394 --enable-libfaac --disable-ffserver --disable-ffplay --enable-libamr_nb --enable-libamr_wb --enable-libvorbis --enable-decoder=h263 --enable-encoder=h263 --enable-decoder=h264 --enable-encoder=h264

Nice. Thank you much. You can actually do the second one with imagemagick already But the first one could be very useful, thanks again.

[the3kgt2]

The convert command is part of imagemagick. You mean there's already a script that converts entire directories?

[jmadero]

yeah I'll have to remember how I did it but I have before on a really large set of pictures that I had that were each over 2 megs and I wanted them way more compact
