Issue with Wildcard in StreamMap

[bchah]

Describe the bug
When using StreamMap with a wildcard in StreamName, FFmpeg raises two errors: "No streams to mux were specified" and "could not create header". The connection occurs (and correctly passes the name of the stream) but no packets appear to be sent.

To Reproduce
Steps to reproduce the behavior:

• Create stream map XML
• Define <StreamName> as * or containing a * (like stream_*)
• Enable stream map in publisher
• Start stream and observe issue

Expected behavior
Use of a wildcard should not prevent the push from occurring properly.

Logs

omelog.txt

Here is the StreamMap config:

<?xml version="1.0" encoding="UTF-8"?>
<PushInfo>
  <Push>
    <Enable>true</Enable>
    <StreamName>*</StreamName>
    <VariantNames>original_video,aac_audio</VariantNames>
    <Protocol>srt</Protocol>
    <Url>srt://192.168.0.187:9998?streamid=publish:${Stream}:from:ome</Url>
  </Push>      
</PushInfo>

Server (please complete the following information):

• OS: Docker Ubuntu
• OvenMediaEngine Version: 0.17.3 and DEV branch

Additional context

• I tested with SRT push
• Changing the StreamName to a full stream name (like "helloWorld") fixes the issue
• I noticed that using ${SourceStream} or ${Stream} as the name had no action as well. I would expect at least ${SourceStream} to act as a passthrough and create pushes for all streams.
• Happy new year! 🥳

@bchah Thanks for reporting. I'll check it out and make improvements.

After testing, I checked that wildcards work well.
The log the error happened because the OutputProfile stream named (StreamName)_preview only had the Image option in its settings.

[Stream Info]

When using SRT for pushing, only Video and Audio data types are transmitted.

I will add the ${SourceStream} macro to soon.

Thanks.

Improved StreamName to allow use of the $<SourceStream> macro. but, I did not add the $<Stream> macro because I don't think there will be any cases where it will be used.

This will be reflected in the next release.

GIVE ME SOME WATER :)

Cheers.

Ah, I see now why the issue occurred. Thank you and I will give it a test with the improvements you made. They look very well hydrated 🤓
