The iPhone application itself is available at spotcrime.com/iphone.php.

The iPhone application has been a success so far and is being used by thousands of iPhone users every day. It is currently the seventh most popular travel application in the Apple iPhone Travel Webapps directory.

Developing this application was a fun project for us because we were able to learn the “ins and outs” of the custom programming functions available to iPhone web applications. Some neat features of the webapp:

• Rotating your phone will cause the map to go full-screen
• User-friendly buttons for navigating the map: the buttons are round and somewhat transparent, making the most of the small screen
• Easily navigable list of cities for which crimes are reported

Next, you can use this command to encode the video:

ffmpeg -y -i INPUT -vcodec libx264 -acodec libfaac -ab 128k -ac 2 -b 640k -threads 4 -flags +loop -cmp +chroma -partitions 0 -me epzs -subq 1 -trellis 0 -refs 1 -coder 0 -me_range 16 -g 300 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -maxrate 10M -bufsize 10M -rc_eq \’blurCplx^(1-qComp)\’ -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 OUPUT

The -vcodec and -acodec options specify the h264 encoder with aac audio. -ab is audio bitrate, if you want to change that, and -b is the video bitrate. You can also specify a size with “-s widthxheight” for instance “-s 640×480″. The -threads option gives you multithreading, I run a quad-core so I have it at 4. All the other flags are h264 options for higher quality. I don’t understand many of them, but it looks nicer with them on.

If you want, you can add “-pass 1″ to the command and run it, and it will generate a log file. Then run it again with “-pass 2″ and it will use the log file for superior variable bitrate results. I highly suggest this.

Lastly, you should pack up the file for iPhone and iPod compatibility:

AtomicParsley OUTPUT -iPod-uuid 1200 –overWrite

Where OUTPUT is the file that you generated with FFMPEG.
