Re-Ordered Tiling Decoding Mosiac Issues

[Lisuibiao]

Hi,

I have been into hevc tiling encoding/decoding. Mosiac issues occur when I tried to decode the tiles with diffrent order than encoding. Here's the encoding parameters:

SvtHevcEncApp -i src.yuv -w 3840 -h 1920 -tile_row_cnt 4 -tile_col_cnt 8 -tile_slice_mode 1 -umv 0 -pred-struct 0 -intra-period 30 -irefresh-type 0 -scd 0 -temporal-id 0 -b out.h265

tile_slice_mode was set to 1, which should indicate that decoding one tile is independent from any other tiles. But why when I try to decode tiles with diffrent order would cause mosiac issues?

Any help will be appreciated!

Hi @Lisuibiao I apologize for the delay in responding to your question. As far as I know, tiling feature is well tested and integrated in other applications. No issue was reported.
If you still have issue on that, could you let me know how to reproduce your issue?
