rtsp_redirect_resolver

Returns rtsp source final destination

Problem:

RTSP RFC defines method called "REDIRECT". Despite the fact RFC was finished at April 1998 it is still possible to some RTSP clients not to support such a feature
Program resolves final destinations of input RTSP sources
That could be described in simple scheme:

RTSP client without REDIRECT support will end up on Read Source1 error

Client -> Source1 -X- Source2 -> Source3 -> Content

By using rtsp_redirect_resolver Source1 resolves to Source3 that is readable by client

Client -> Source1 -> Source2 -> Source3 -> Content

Build:

make build

Run:

make args='<run arguments>' run

Usage:

rtsp_redirect_resolver <format> sources...

where format is one of:
args - prints result in single row, all final sources separated by single space, each
nl - prints result in multiple rows, all final sources separated by newline \n
json - print result as json array to redirect_sources.json file
csv - print result as table to redirect_sources.csv file
http:<port>:<refresh_interval_seconds> - returns result on HTTP API at 'GET localhost:<port>/', input sources are refreshed and resolved every <refresh_interval_seconds>

supported sources:
http|https - fetches url that contains json array and adds it to input list
json - parses local file containing json array and adds it to input list
rtsp|rtsps - just adds source to input list
csv - parses local csv file and adds it to input list

example:
rtsp_redirect_resolver args rtsp://127.0.0.1/stream1 https://mybroadcast.com/broadcasts ~/local_broadcasts.json
rtsp_redirect_resolver http:8123:3600 rtsp://127.0.0.1/stream1 https://mybroadcast.com/broadcasts ~/local_broadcasts.json
