This test limits the amount of palette_run syntax element decoded for the index mode of the current palette implementation. When the colour index is larger than a threshold, the palette_run is not signalled. The issue of the parsing dependency noted for this contribution will be investigated.

Some gain was shown – 0.0 to 0.5% per source content category (all-intra).

Note: Parsing depends on reconstructed palette index values.
