SrtUrl does not support SRT v1.4.0 or higher PACKETFILTER socket option

[tbudaiatos]

In order to be able to set properly the SRT forward error correction on connection both sides have to negotiate it.
So far it is only possible to use default setting, no FEC.

https://github.com/Haivision/srt/blob/master/docs/API/API-socket-options.md#srto_packetfilter

We would like to be able to define if FEC is enabled and optionally to define cols and rows values
as per https://github.com/Haivision/srt/blob/master/docs/features/packet-filtering-and-fec.md#configuring-the-fec-filter

packetfilter option is set in pre connection phase

Hi,
SrtUrl purpose is that srtdroid supports FFmpeg srt URL.
Since it is now public maybe we can add it.
As your use case is to set this settings in StreamPack we could add the setSockFlag in the SrtEndpoint.
Wdyt?

My POV is that this should be part of srtdroid, due to the fact that the SRT Url can contain FEC configuration
srt://recv.com:5000?latency=500&packetfilter=fec,cols:10,rows:5

srtdroid should support the format srt://[host]:[port]/?[options] and all the optios the used https://github.com/Haivision/srt defines and supports.

It should be to the end application or StreamPack if all or only some options will be used. As already stated srtdroid is a binder/wrapper for Android built on [SRT](https://github.com/Haivision/srt)
