H265 RTP Streaming

[Tharun K]

Hello all,

As the subject says, I am trying to stream H265 transcoded from FFMPEG. I was successful with H264, so I am now trying with H265. I have gone through the Google Group but haven't found any solution.

FFMPEG command: ffmpeg -rtsp_transport tcp -i rtsp://<IP of Camera>/Steaming1/Channel1/101  -c:v libx265 -b:v 1M -r 24 -g 60 -an -f rtp rtp://127.0.0.1:8004

Janus Configuration:

I've tried both ways, commenting and uncommenting videofmtp but to no avail

This is the error I am getting when testing on Safari (version 15.5, which support H265)

Error:  WebRTC error... Failed to set local answer sp: Failed to set local video description
recv parameters for -section with mid-'v'

Also, attaching the SDP offer 



I am new to this field, any help would be appreciated.

Thanks,
Tharun
