The SDP looks be able to be parsed by the following code:
package main
import (
"fmt"
"github.com/pion/sdp/v2"
)
func main() {
s := &sdp.SessionDescription{}
err := s.Unmarshal([]byte(`v=0
o=NVR 1585015269 1585015269 IN IP4 0.0.0.0
s=3GPP Unicast SDP
c=IN IP4 0.0.0.0
t=0 0
a=range:npt=0-
a=control:*
m=video 0 RTP/AVP 96
a=control:video_0
a=rtpmap:96 H264/90000
a=fmtp:96 profile-level-id=42002a;sprop-parameter-sets=Z0IAKp2oHgCJ+WbgICAgQA==,aM48gA==;packetization-mode=0
m=audio 0 RTP/AVP 8
a=control:audio_0
a=rtpmap:8 PCMA/8000`))
if err != nil {
panic(err)
}
fmt.Printf("parsed:\n%+#v\n\n", s)
b, err := s.Marshal()
fmt.Printf("roundtrip:\n%s\n", b)
} output:

Could you post your code and error log?

I'm not very sure SDP allows empty lines.
I'll check the RFC and BNF definition of SDP.

In my understanding, extra newlines in SDP is not fully adapting the specification. (I'm not 100% sure.)
But other SDP parsers, for example one in VLC media player, allow to have extra newlines.
#46 will fix the issue.
