Tools

[ TSGen ] - Updated: 9/29/03
Program to model frame loss (or packet loss) in streaming video. Requires input from cdfgen and autogen tools. Output is a time series of numbers whose statistics closely match the first-order statistics and autocorrelation of the input.

[ autogen ] -
Program to calculate and output the autocorrelation values of an input file up to a user-specified lag.

[ cdfgen ] - Updated: 9/04/03
Program to calculate and output the empirical CDF of an input file.

Note: For an example trace to test the above tools on, download this.

----------------------------

[ ssrc ] -
Program to display the SSRC numbers (if they exist) of incoming packets. This product includes software developed by the Politecnico di Torino, and its contributors. Requires Packet.lib, Packet32.h, DEVIOCTL.H, Ntddndis.h, and a video stream that uses RTP. Designed for use with vpgrab.

[ vpgrab ] -
Program to capture MPEG 1/2 video stream packets and display lost and received packets. Requires the SSRC number of the stream. This product includes software developed by the Politecnico di Torino, and its contributors. Requires Packet.lib, Packet32.h, DEVIOCTL.H, Ntddndis.h, and a video stream that uses RTP.

[ pktconvert ] -
Program to generate counts from an input of 0's and 1's. Used for converting the 0's and 1's displayed by vpgrab into counts of 0's and 1's.

[ empgen ] -
Program to generate empirically distributed random variables from counts of 0's and 1's. Output are counts of 0's and 1's that are of the same distribution as the input. Designed for use with pktconvert.

[ bingen ] -
Program to generate 0's and 1's from an input of packet counts. Designed for use with empgen.

----------------------------

[ MPEG Frame Catcher ] -
Catches packets and displays information on MPEG1/2 streams including timestamp, size, temporal reference number, sequence number, and frametype. This product includes software developed by the Politecnico di Torino, and its contributors. Requires Packet.lib, Packet32.h, DEVIOCTL.H, Ntddndis.h, and a stream that uses RTP.

[ MPEG Frame Catcher Output Parser ] -
Parses the output of the MPEG Frame Catcher and consolidates the packets into frames. This parser outputs the timestamp and the frame, with the timestamp being the timestamp of the first packet in the frame. Accepts only the output of the MPEG Frame Catcher.

[ parser.pl ] -
This Perl script parses index logs from the packet analyzer program called Analyzer. It can filter out any unwanted packets, seperate the data into two sets for each IP address and two sets for the packet size and delta time between packets for each of those IP addresses. The script is easily modified to fit any use.
