I'm trying to do a simple health check of RTSP stream with curl tool.
But command like this always gives me 404 Stream Not Found error:

    curl -v --url rtsp://192.168.1.80/h264/ --user admin:1234
    * Trying 192.168.1.80...
    * Connected to 192.168.1.80 (192.168.1.80) port 554 (#0)
    * Server auth using Basic with user 'admin'
> OPTIONS * RTSP/1.0
> CSeq: 1
> User-Agent: curl/7.47.0
> Authorization: Basic YWRtaW46YWRtaW4=
>
    < RTSP/1.0 404 Stream Not Found
    < CSeq: 1
    < Date: Tue, Feb 27 2018 01:14:21 GMT
    <
    * Connection #0 to host 192.168.1.80 left intact

But it looks like that RTSP_STREAM_URI is not set. so `*` is used instead
here:
`> OPTIONS * RTSP/1.0`

For instance, I tested the same URI with VLC media player and captured
packets with tcpdump. With VLC it works and I can see the video without any
issues and data send in request to RTSP server looks like this as observed
in tcpdump:

    OPTIONS rtsp://192.168.1.80:554/h264 RTSP/1.0
    CSeq: 2
    User-Agent: LibVLC/2.2.2 (LIVE555 Streaming Media v2016.02.09)

It looks that there is an option `CURLOPT_RTSP_STREAM_URI` in libcurl under
the hood of curl tool, but I can't find command line option to set this
parameter so `*` is used as default value according to this:
https://curl.haxx.se/libcurl/c/CURLOPT_RTSP_STREAM_URI.html
And it doesn't automatically use value of --url neither.

How to set CURLOPT_RTSP_STREAM_URI in curl tool?
Thank you
