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

	2

	3 Run the tool as follows:

	4

	5 python rtp_analyzer.py <rtc event log>

	7 where <rtc event log> is a recorded RTC event log, which is stored in

	8 protobuf format. Such logs are generated in multiple ways, e.g. by

	9 Chrome through the chrome://webrtc-internals page.

	10

	11 The script has been tested to work in python versions 3.4.1 and 2.7.6,

	12 but should work in all python versions for which there is a version

	13 of the dependencies.

	16 ------------

	18 The analyzer script needs numpy (http://www.numpy.org/) and

	19 matplotlib (http://matplotlib.org/).

	20

	21 A version of Protocol Buffers is needed as well. One is distributed

	22 along with WebRTC in `thirdparty/protobuf/python`. This tool also

	23 needs a file `rtc_event_log_pb2.py` which is automatically generated

	24 from `webrtc/call/rtc_event_log.proto` and placed in

	25 `out/<TARGET>/pyproto/webrtc/call/` with every WebRTC compilation. To

	26 use it, WebRTC needs to be compiled before using this tool.

	27

	28 An alternative to compiling WebRTC is to install your own version of

	29 Protocol Buffers and `protoc`, the Protocol Buffer compiler.

	30

	31 If you use your own version of protobuf, generate the python file in

	32 this folder with

	33

	34 protoc -I $WEBRTC_ROOT/webrtc/call $WEBRTC_ROOT/webrtc/call/rtc_event_log.pro to --python_out ./
