chrome-webrtc-packet-log-parser
Project status
At this point the project is primerly intended to be used by checking it out and modifying main.go, however you can also use it by downloading the binaries from releases.
Overview
Go command-line application to make chrome generated webrtc diagnostic packet and event recording human readable.
For more information see here.
To regenerate proto files, call docker-compose up in this directory.
How to execute
go run main.go <log file>
Example output:
$ go run main.go webrtc_event_log_20200514_1817_191_3.log
webrtc_event_log_20200514_1817_191_3.log opened
