Bug Report: SDP Compatibility Issue with Majestic Streamer on Ingenic T31x

[IPC-Probe]

Description

I’m using an IP camera based on the Ingenic T31x chipset, which uses the Majestic RTSP streamer. When streaming to an older client system (e.g., legacy FFmpeg/GStreamer/VLC), the video stream fails to initialize properly.
After investigation, the issue appears to originate from the SDP (Session Description Protocol) response during the RTSP DESCRIBE phase.
The profile-level-id in the a=fmtp line appears to be missing or invalid.
The sprop-parameter-sets (SPS/PPS) are not included in the SDP.

how to fix this?

thanks!
