* feat: improve RTMP control message compatibility with non-standard cameras
- Add flexible chunk stream ID validation for control messages
- Support common non-standard chunk stream IDs (2,3,4,5,6) used by various cameras
- Maintain backward compatibility with standard RTMP clients
- Fix connection issues with PTZ cameras using chunk stream ID 4
This resolves compatibility issues with IP cameras that don't strictly follow
RTMP spec while maintaining full support for standard RTMP implementations.
Previously, cameras using non-standard chunk stream IDs would fail with
'unexpected chunk stream ID' errors. Now MediaMTX provides nginx-rtmp level
compatibility with real-world camera implementations."
* add tests
* entirely remove control chunk stream ID validation
