This file describes how to set up and use the RTP log analyzer.

First build the tool with

    ninja -C out/my_build webrtc:rtp_analyzer

The tool is built by default, so

    ninja -C out/my_build

is enough.

After building, run the tool as follows:

    ./out/my_build/rtp_analyzer.sh [options] <rtc event log>

where <rtc event log> is a recorded RTC event log, which is stored in
protobuf format. Such logs are generated in multiple ways, e.g. by
Chrome through the chrome://webrtc-internals page.

Options:
  -h, --help            show this help message and exit
  --dump_header_to_stdout
                        print header info to stdout; similar to rtp_analyze
  --query_sample_rate   always query user for real sample rate

The script has been tested to work in python versions 3.4.1 and 2.7.6,
but should work in all python versions.

Working versions of NumPy (http://www.numpy.org/) and matplotlib
(http://matplotlib.org/) are needed to run this tool. See this link
with installation instructions (http://www.scipy.org/install.html).
