The stream is being transcoded repeatedly in an infinite loop, ultimately leading to a program crash. Is this a bug in SRS, or is there an issue with the configuration?

The setup is primarily using default settings, with the addition of transcoding configuration.

When configuring the transcode profile, if an application name or stream name is not specified after 'transcode', it will transcode all streams. This results in the output stream being transcoded, creating an endless loop of transcoding. Therefore, when setting up the transcode configuration, it is necessary to specify either an application name or a stream name. For example, if the specified application name is 'live', the output should be renamed to something different to avoid an infinite transcoding loop. It is suggested that this information be clearly stated in the documentation to prevent mistakes by those who are new to this process.
