FFmpeg auth fail with long rtsp urls

[Ruslan]

Summary of the bug:
Trying to get long url rtsp stream with Authorization cause Authorization problem (method SETUP failed: 401 Unauthorized)

How to reproduce:

This works (Length of uri is 116)

% ffmpeg -i "rtsp://user:password@192.168.0.8:554/Streaming/tracks/401?starttime=20170720T221248Z&endtime=20170720T221330Z&names=00000000033222"  -vcodec copy -an video.mp4

This don't works

% ffmpeg -i "rtsp://user:password@192.168.0.8:554/Streaming/tracks/401?starttime=20170720T221248Z&endtime=20170720T221330Z&names=000000000332221"  -vcodec copy -an video.mp4

Length of uri is 117

RTSP DESCRIBE succeed, but SETUP command add /trackID=video that cause url size to be 131 in second case.

It looks like authenticated urls has limit for 130 chars.
Setting or not setting port in url doesn't affect as in RTSP requests ffmpeg always add port, but IP address affects. So having 192.168.0.245 instead of 192.168.0.8 reduce working path by 2 chars.
For not protected urls there are no such problem.
