Field ffmpeg reported 'Option rw_timeout not found' and exited, causing a reconnect loop. rw_timeout is an avio/protocol option, not an RTSP demuxer option; the RTSP socket timeout is build-specific (-stimeout / -timeout). Omit it for portability — a dead TCP connection still ends decode and triggers reconnect. Keeps transport and low-latency flags. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
