HI， I want to do tile streaming and follow the instruction in https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide

However, after I package the video and ran the following code:

MP4Box -add video_tiled.hvc:split_tiles -new video_tiled.mp4
MP4Box -rem 3 video_tiled.mp4 -out test_tile_lost.mp4

I had some problems opening the output video (video_tiled.mp4 test_tile_lost.mp4). I tried several ways to open but all failed:

1） gpac -i video_tiled.mp4 
No filter chain found for PID video_tiled.mp4 in filter fin to any loaded filters - NOT CONNECTED

2）ffplay video_tiled.mp4
No decoder could be found for codec none
Failed to open file 'video_tiled.mp4' or configure filtergraph

3） I open the mp4 file with the some players and it turns out that  hvt1 and hvc2 decoder are required.

Besides, I also found some problems with the gpac, like when I ran:

gpac -gui
[Compositor] Failed to load a video output module.
Failed to load filter "compositor:player=gui": I/O Error

I am new to this and I have looked the issues and cannot find the solutions.  I think I have the same issue with https://github.com/gpac/gpac/issues/1550#issue-665001400  , but it is closed.

Thanks a lot if you could give some suggestions !
