Media3 main branch

More version details

I am encountering an issue when trying to playback an RTSP URL with the following SDP:

v=0
o=- 1109162014219182 0 IN IP4 0.0.0.0
s=HIK Media Server V4.72.107
i=HIK Media Server Session Description : standard
e=NONE
c=IN IP4 0.0.0.0
t=0 0
a=control:*
b=AS:4106
a=range:clock=20250319T200000Z-20250319T210000Z
m=video 0 RTP/AVP 96
i=Video Media
a=rtpmap:96 H264/90000
a=fmtp:96 profile-level-id=4D0014;packetization-mode=0
a=control:trackID=video
b=AS:4096
m=audio 0 RTP/AVP 0
i=Audio Media
a=rtpmap:0 PCMU/8000
a=control:trackID=audio
b=AS:10
a=Media_header:MEDIAINFO=494D4B48020100000400000110710110401F000000FA000081000000000000000000000000000000;
a=appversion:1.0

I noticed that the a=range:clock=20250319T200000Z-20250319T210000Z results in a ParserException in Media3. Is there a way for me to fix this?
I searched on the issue page, but I couldn't find any issues related to the problem I'm facing.
