App does not stream RTSP - missing line on RTSP Server response - how to suppress

I'm working with a non-compliant RTSP server, but I really want to use Exo libs. I want to know a way to suppress the following issue on my camera response:

App will try to play:
```
D/RtspClient: PLAY rtsp://192.168.99.1/media/stream2 RTSP/1.0
User-Agent: ExoPlayerLib/2.16.1
CSeq: 4
Session: 2tgy24fmtzkfnz25hne2caa4
Range: npt=0.000-
```
And here is the incomplete response:
```
D/RtspClient: RTSP/1.0 200 OK
CSeq: 4
Date: 1 1 1970 1:58:36 GMT
Session: 2tgy24fmtzkfnz25hne2caa4
```

This missing line causes the app to raise an exception: "Server did not provide timing for track".

As the issue #9664 suggests, I commented the lines 515-520 from `RtspMediaPeriod`, but I can't play my stream yet. The following happens:

```

As you can see, after the first PLAY in UDP, occurs the TEARDOWN. After this TEARDOWN, the app sends OPTIONS again and again.

Is this due to that missing line? If yes, how can I suppress it? If not, what's going wrong?

Thank you all!
