Overriding tcUrl and other options with ffplay (BASH)

Category: BASH

Various non-standard RTMP applications rely on the the values of attributes that are commonly passed in as part of a PLAY call, such as tcUrl, pageUrl etc. Sometimes this is for authentication (and content protection) purposes, sometimes it's to implement a DNS name based namespace so that different domains can share the same app. With ffmpeg and ffplay it's possible to override tcUrl and other variables with a command line option
