Convert Video for Flash Streaming

August 1, 2010 , , Comment

This is a simple script I’m using to convert the videos I take on my Canon S90 for posting online using a flash player.

#!/bin/bash
# Convert videos from Canon S90 to flash-playable streaming format
for file in "$@"
do      
        filename=$(basename $file)
        filename=${filename%.*}
        # Convert the audio stream to AAC
        ffmpeg -i $file -vcodec copy -acodec libfaac temp_vid.mp4
        # Move the H.264 MOOV atom to the beginning of the file for progressive streaming
        qt-faststart temp_vid.mp4 $filename.mp4
        rm temp_vid.mp4
        # Create a screenshot
        ffmpeg -i $filename.mp4 -f image2 -vframes 1 $filename.jpg
done

XBMC Boxee UI Switcher

July 22, 2010 , , , , Comment

I bind this script to a button on my LIRC remote to easily switch between XBMC and Boxee on my HTPC. XBMC’s interface using the Rapier skin and fanart is much more attractive, but Boxee offers great social network integration (read: Youtube).

#/bin/bash
# Switch between XBMC and Boxee
if ps ax | grep -v grep | grep xbmc.bin > /dev/null
then
	echo "XBMC running, killing process"
	kill `pidof xbmc.bin`
	sleep 7
	echo "running Boxee"
	/usr/bin/runBoxee &
elif ps ax | grep -v grep | grep Boxee > /dev/null
then
	echo "Boxee running, killing process"
	kill `pidof Boxee`
	sleep 7
	echo "running XBMC"
	/usr/bin/runXBMC &
else
	echo "No UI running, starting XBMC"
	/usr/bin/runXBMC &
fi
