RTSP stopped working on Wyze Cam v3 (firmware 4.36.16.7064)
I've had the official Wyze RTSP firmware running on a Cam v3 for a while, feeding into Frigate/ffmpeg — worked fine initially. After updating a few firmwars ago, RTSP has completely stopped responding.
Symptoms:
- Camera is reachable on the network (ping works, TCP port 554 accepts the connection).
- Any RTSP client (ffmpeg, tested with -rtsp_transport tcp) connects at the TCP level ("Successfully connected") but the RTSP handshake itself fails immediately — Invalid data found when processing input. Even at ffmpeg's most verbose debug logging, no RTSP reply is ever logged, meaning the server isn't sending back anything ffmpeg recognizes as a valid RTSP response.
- Same failure on both the standard /stream0 path and other paths tried.
- RTSP is confirmed enabled in the camera's local settings, credentials unchanged from when it was working.
What I've ruled out:
- Not a credentials/auth issue — the failure happens before any auth challenge would occur.
- Not a network/firewall issue on my end — TCP connects fine, and other devices on the same subnet/VLAN work as expected.
Has anyone else seen RTSP break after the initial release of the RTSP feature, specifically? Trying to figure out if this is a known regression in recent firmware builds before I roll back or file a support ticket.
Any workarounds appreciated.
