Larix mobile app and SRS

[KariKuusik]

When setting Larix mobile app to stream over rtmp it handshakes, but never sends the stream name, only app.
After that SRS drops the connection.
My SRS version is 7.0.93

This is not an empty stream name problem as initially suspected. The logs show that Larix successfully completes the RTMP handshake and connects to the /live application, but then fails to complete the RTMP publish workflow.

If it were truly an empty stream name issue, SRS would log:

[ERROR] serve error code=2051(StreamNameEmpty)(Invalid stream for name is empty) : rtmp: empty stream

But we only see error 1007 (ERROR_SOCKET_READ), which indicates a network-level socket read failure, not an application-level validation error.

Please provide more information.
