Hi, so it looks like the compositor still has issues whilst trying to playback live tiled dash streams as it stops and displays:

`[Compositor] Could not detect end of stream(s) in the last second, aborting`

However, when just playing in normal mode (dashin->vout), the stream plays back smoothly.

Here are the commands used:

For the encoder:

```
#!/bin/bash

export ISIZE=6000x3000
export TILES=6x6
export OSIZE=1024x512

gpac -i test_30fps.mp4:FID=I reframer:rt=on:SID=I:FID=REGULATED\
	ffsws:SID=REGULATED:FID=Y:osize=$OSIZE:ofmt=yuv420 -+kvazaar-params=preset=ultrafast,tiles=$TILES,slices=tiles,mv-constraint=frametilemargin,input-format=P420,qp=16,rc-algorithm=lambda,input-fps=30\
	ffenc:SID=Y:FID=K1:c=libkvazaar:b=10M:size=$OSIZE:fintra=4:rc\
       	tilesplit:SID=K1:FID=1\
       	-o http://localhost:8080/live.mpd:gpac:dmode=dynamic:segdur=4:cdur=2:asto=2:llhls=off:profile=live:rdirs=outdir:template=seg_live_:SID=1  -stats -logs=all@info -lu -log-file=file_to_tiles.log
```

For the compositor playback:

```
#!/bin/bash

gpac  -blacklist=nvdec --lowlat=no compositor:src=http://192.168.123.203:8080/live.mpd#VR vout:buffer=8000 -graph -logs=dash@info -lu -log-file=play_compositor_not_ok.log
```

For the regular playback (dashin->vout)

```
#!/bin/bash

gpac -i http://192.168.123.203:8080/live.mpd dashin:lowlat=no tileagg ohevcdec vout:buffer=8000 -graph -logs=dash@info -lu -log-file=play_equirect_ok.log
```

As you can see, the content is streamed and played back from 2 different machines, on the same gigabit local network. (this could have an effect)

Both machines run:
GPAC version 1.1.0-DEV-rev1382-g08e1f404e-master
Ubuntu 21.04
