How to use ffmpeg svt-hevc encoding to start TileSliceMode mode, can you give an example of the command

[jpt666]

(Prerequisite svt-hevc encoder I have added to ffmpeg)
I tried to use the following command to push the stream successfully and play it successfully, but I am not sure whether the following command starts TileSliceMode mode, and tile is divided into 12x12 blocks. Could you please help me confirm whether there is any problem with the command, because the result of the live stream of gpac dash does not have tile? But I use gpac for local mp4 files dash has tile

ffmpeg -re -stream_loop -1 -i /home/jinpengtao_wd/desktop/8k-30s.mp4 -c:v libsvt_hevc -vf scale=3840:1920 -rc 1 -profile 2 -level 0 -tier 0 -umv 0 -tile_slice_mode 1 -tile_row_cnt 12 -tile_col_cnt 12 -f rtsp -rtsp_transport tcp rtsp://192.168.1.104/live/test

Appendix:
Local gpac for local mp4 file tile dash is the process command (svt-hevc encoder is used in part 2).
