Detailed guidelines: http://gpac.io/2013/07/16/how-to-file-a-bug-properly/

My machine 
- `Ubuntu 64bit 18.04.6 LTS`
- `memory` 32GB
- `CPU` AMD Ryzen 7 3700x 8-core processor × 16 
- `GPU` NVIDIA GeForce GTX 1660 Ti/PCIe/SSE2


Also tried with building everything on my own (besides ready build apps) with branches
- `gpac` HEAD detached at v2.2.0
- `ffmpeg` release/5.1
- `local rtsp server` gstreamer (1.20)


I have a local rtsp server streaming from  a live camera, I want to re-encode the stream to support tiles in order to drop some of them and stream it again

1st step to see if encoding works:
 - gpac -i rtsp://127.0.0.1:1234/live.sdp:gpac:enc:c=libkvazaar:input-res=1920x1080:bitrate=2000000:fintra=1:rc::kvazaar-params=tiles=3x3,slices=tiles,input-fps=30 -o http://localhost:8080/live.m3u8:gpac:dmode=dynamic:rdirs=./

and I can use a media player with no problem (there is a 30sec delay)

2nd step to drop tiles:
- gpac -i rtsp://127.0.0.1:1234/live.sdp:gpac:enc:c=libkvazaar:input-res=1920x1080:bitrate=2000000:fintra=1:rc::kvazaar-params=tiles=3x3,slices=tiles,input-fps=30 tilesplit:tiledrop=1 tileagg -o http://localhost:8080/live.m3u8:gpac:dmode=dynamic:rdirs=./

Get a lot of errors
````
[RTP] Rejecting too early packet (TS -1666837258 vs signaled rtp time 1 - diff 43389 ms)
````
3rd step to drop tiles with the addition of live profile:
- gpac -i rtsp://127.0.0.1:1234/live.sdp:gpac:enc:c=libkvazaar:input-res=1920x1080:bitrate=2000000:fintra=1:rc::kvazaar-params=tiles=3x3,slices=tiles,input-fps=30 tilesplit:tiledrop=1 tileagg -o http://localhost:8080/live.m3u8:gpac:profile=live:dmode=dynamic:rdirs=./

No files are created locally (`live.m3u8` and `media segments`) and nothing is streaming. Just the message on the terminal
