ArrayIndexOutOfBoundsException H264Packetizer

[GoogleCodeExporter]

There is a crash after few first frames are shown on VLC. Seems to be a problem 
with signed int. How about using long instead?

        public int read(byte[] buffer, int offset, int length) {

            //length = length>available() ? available() : length;

            length = length<0 ? 0 : length;

After added sanity check above:
