fix(v2): drop rw_timeout ffmpeg option rejected by the RTSP demuxer

Browse Source 
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.
