I'm trying to integrate `GF_FileIO` to my project and I've managed to read regular/static files but the same code fails for DASH input. It manages to get the manifest and then it tries to read the manifest again (then immediately closes it). Even if I force my code to recreate the request and feed a valid stream it fails immediately.

The error I'm getting:
```
[DASH] Error - cannot connect service: wrong file type gfio://0xf61b08
[DASHDmx] Error - cannot initialize DASH Client for gfio://0xf61b08: Requested URL is not valid or cannot be found
Filter dashin failed to setup: Requested URL is not valid or cannot be found
```
Actual test URL: https://livesim2.dashif.org/livesim2/mup_30/testpic_2s/Manifest.mpd

What I'm trying to understand is how does DASH/HLS is utilizing `GF_FileIO`. For regular files, it seems to be easy. Lifecycle seems to be like this `open->tell/eof->read->close`. However, I think for DASH this is a bit different, right?
