SRT Publisher url generating #1847

OME Version 0.18.0

The docs says that the publisher url should be specified in this format: srt://edge.com:9030?streamid=default/app/stream/playlist
But when I try to connect, I see this error in the logs:

[2025-05-27 11:05:07.122] E [SPSRTPub-s9030:133] AccessController | access_controller.cpp:221  | Could not resolve the domain: default

I also tried to specify a link in this form, but also unsuccessfully:
srt://edge.com:9030?streamid=default.edge.com/app/stream/playlist

[2025-05-27 11:16:17.563] E [SPSRTPub-s9030:133] SRTPublisher | srt_publisher.cpp:440  | Could not find vhost/app: #default.edge.com#app

If use the old link format (srt://edge.com:9030?streamid=srt://default.edge.com/app/stream/playlist?), then everything works fine with the following warning:

[2025-05-27 11:11:00.510] W [SPSRTPub-s9030:133] SRTPublisher | srt_publisher.cpp:303  | The srt://... format is deprecated. Use {vhost}/{app}/{stream} format instead: srt://default.edge.com/app/stream/playlist

What am I doing wrong?

Thanks to your report, I discovered an issue where the SRT Publisher could not properly resolve the vhost or app.
(This occurs when the VirtualHost.Name and Host.Names.Name are different.)
Since I don't have time to fix it right now, please use the following method as a workaround for this issue:

              <Names>
                <Name>*</Name>
              </Names>

This seems to have occurred because there is no default virtual host. Could you please upload your Server.xml?

Since the name of the virtual host you created is d7d02a3f-14bc-4229-815a-2593d4094f94, you need to access it using d7d02a3f-14bc-4229-815a-2593d4094f94/app/stream instead of default/app/stream.
If you want to use the default, you can either replace that name with default when you create the virtual host, or refer to this example and add a <VirtualHost> to your Server.xml.

I must have explained it incomprehensibly.
I deliberately replaced the vhost name to "default" in both links and logs so as not to complicate things.

I have now added to server.xml vhost and app, but the result is the same((

Thanks to your report, I discovered an issue where the SRT Publisher could not properly resolve the vhost or app.
(This occurs when the VirtualHost.Name and Host.Names.Name are different.)
Since I don't have time to fix it right now, please use the following method as a workaround for this issue:

              <Names>
                <Name>*</Name>
              </Names>

@dimiden, thanks for the help! I added the following name to the config and it worked:

            <Name>default</Name>
            <Host>
              <Names>
                <Name>default.edge.com</Name>
                <Name>default*</Name>
              </Names>

I understand that you have already resolved this, and if you are using the above settings, there is nothing you need to change. I'm just leaving this comment for your reference.

I resolved the issue where using the vhost/app/stream format previously caused it to behave differently from other Providers/Publishers and was not intuitive. From now on, please use the host/app/stream format instead.
