When playing back a live DASH with tiles using the compositor and a BIFS scene description, it looks like the playback stops after one segment. With this warning:

```
[Compositor] Could not detect end of stream(s) in 10001 render pass, aborting
``` 

Note: it also happens very often whilst using the compositor as a source like:

```
gpac compositor:src=http://localhost:8080/live.mpd vout:buffer=8000
```

Encoding command:
```
gpac\
 -i test_30fps.mp4:FID=I reframer:rt=on:SID=I:FID=REGULATED\
 ffsws:SID=REGULATED:FID=Y:osize=1024x512:ofmt=yuv420\

[Here are the files related to this issue](https://www.mediafire.com/file/0z12jns5kxvomhk/compositor_bt.zip/file)

- the logs from the player when the mp4 file is used in the .bt file
- the logs from the player when a DASH input is used
- the video file itself
- both .bt files

Side questions:

- How can we influence upstream parameters from the compositor? (lowlat/tiledrop)
- The playback using live DASH sources seems very choppy too, maybe this is also related to this issue.
