Hello,

I am trying to set the buffer of the playback to 2 seconds using this command:
```
gpac httpin:src=http://localhost/dash/coaster2/coaster2_6x3.mpd dashin tileagg ffdec  inspect:buffer=2000:dur=5 -graph
```
However, it seems the playback buffer is overwritten by some configuration. The streaming session also hang. Here is the error:

Setting buffer less than 1000 will resume the playback again. Can you please let me know a way to set playback buffer for the inspect filter?.
