RTMP: Support publish with Server without StreamKey using OBS

[winlinvip]

To publish rtmp://ip/live/livestream?k=v to SRS, the correct way to use OBS:

• Server: rtmp://ip/live
• StreamKey: livestream?k=v

However, sometimes the StreamKey has maken lots of people confused, they will literally use as bellow, easpecially for fresh man:

• Server: rtmp://ip/live/livestream?k=v
• StreamKey: Empty

And it's easy to understand.

Solution

So, SRS might should support to extract the stream from Server if StreamKey is empty.

That is, if config OBS as:

• Server: rtmp://ip/live/livestream?k=v
• StreamKey: Empty

Covert it to:

• Server: rtmp://ip/live
• StreamKey: livestream?k=v

And it's compatible with SRT.

Notes

If use SRT, you should put the whole string to Server and leave the StreamKey empty, like this:

• Server: srt://cvm.ossrs.net:10080?streamid=#!::r=live/cfpkdc,m=publish

And there are serval questions about the OBS config:

• Problem with config Ingest RTMP to connect OBS to Restreamer: Could not access the specified channel or stream key
• How to publish rtmp://example.com using OBS

It's confusing.
