I've been using GPAC v2.0 for some time now. I'm trying to upgrade to the latest release, that of v2.2.1, but I'm facing some issues.

# Use Case
From and RTMP Stream, create multiple qualities of Low Latency HLS with specific configurations using linked filters.

> The exact command works perfectly in v2.0, but in v2.2.1 it fails on the first filter. It seems like some issue with fetching from source.

```

```
Has there been any such change that deprecates this command? If so, how can I achieve the same/similar (or maybe better) result with the new release?
