you need to understand why it is empty and not allow it to be empty.

you need to understand why it is empty and not allow it to be empty.

if rtsp DESCRIBE not have sprop-sps sprop-pps sprop-parameter-sets 。The code copied by some people doesn't parse these contents and push the stream 。
update parser.go like this
`
func (self CodecData) SPS() []byte {
if len(self.RecordInfo.SPS) > 0 {
return self.RecordInfo.SPS[0]
} else {
return nil
}
}

func (self CodecData) PPS() []byte {
if len(self.RecordInfo.PPS) > 0 {
return self.RecordInfo.PPS[0]
} else {
return nil
}
}

why in your https://github.com/deepch/RTSPtoWebRTC/blob/master/config.go
if codecVideo.SPS() != nil && codecVideo.PPS() != nil && len(codecVideo.SPS()) > 0 && len(codecVideo.PPS()) > 0 {
//ok
//log.Println("Ok Video Ready to play")
}
`
if codecVideo.SPS() == nil is panic
