Hi,
I am trying to use Kvazaar as a GPAC filter with input being rtmp live stream currently from OBS, but in future maybe from other camera. 

I tried it with local mp4 file and it is working correctly (I got mpd file and a lot of m4s files). When I put just rtmp://myUrl/live instead of file.mp4 I got this:
![gpac_5](https://user-images.githubusercontent.com/82051773/118245945-a7a0ce00-b4a1-11eb-8f1c-9700a610fc29.png)
and no output files, and when I add :dmode=dynamic at the end of the command, I get _*** buffer overflow detected ***: gpac terminated_ . Is there something else I should do if my input is live? Should I do it in other way? Basically I would like to split live video into tiles, encode tiles to different qualities, and play it while somehow telling which quality of each tile to use.
Thanks

The issue indicates a buffer overflow when using the GPAC tool with a live RTMP stream, which can lead to potential security vulnerabilities such as Denial of Service (DoS) or arbitrary code execution if exploited. This is a serious concern as it suggests that the application does not handle input validation properly, especially with dynamic data streams.
