stallTimeout

How long a read may wait without progress before the session ends with PlaybackError.SourceStalled. Duration.INFINITE waits for ever.

The count runs only while the engine waits for the source: a packet read, an open that reads through a MediaIo, or the read of an external subtitle file. A packet from the source or bytes from the reader start it again, so a slow source that still delivers never stalls. An open through the backend's own protocols is bounded by their timeouts instead. An external subtitle file that stalls is skipped with a warning instead. Ending a read needs a source that can interrupt; the FFmpeg backend can.
