Switched to another version, which is the latest development branch, the "develop" branch, and the issue is no longer present.

Looking at the logs, there seems to be an issue with the MPEG-TS stream. The initial fields are incorrect, causing an assertion error. Could you please check if the streaming is in MPEG-TS format?
