I am trying to use GPAC for transferring DASH files over ROUTE protocol as per ATSC 3.0 standard. Following documentation from the GPAC wiki shows a basic howto guide.
https://wiki.gpac.io/Howtos/route/
On that basis of above howto I am doing the following::
1. I have a directory with correct dash manifest and audio/video segment files. There i am issuing the following command:
`   gpac -i index.mpd dashin:forward=file -o route://225.1.1.0:6000`
   
2. and then I am trying to play it using the following command:
`  gpac -play route://225.1.1.0:6000`

Error:
`[Socket] Asked to set socket receive buffer size to 524288 but system used 425984
[AudioOut] No audio output modules found, cannot load audio output
Filter aout failed to setup: I/O Error
Failed to load filter "aout": I/O Error
session error: I/O Error
Filters not connected:
routein (src=route://225.1.1.0:6000) (idx=1)
No filter chain found for PID PID1 in filter routein to any loaded filters - NOT CONNECTED`

3. Also I tried to do the following and then play udp stream in VLC:
  `gpac -i route://225.1.1.0:6000/ -o udp://225.1.1.10:1234/:ext=ts`
  
  But none of them seem to be playing anything at all.
