To reduce performance issues with 8x serial pipelines, please refer to chapter# 40 of Section VI: Appendices for IRQ Balancing scheme in PG252 [TODO: To be updated by 27th October, 2021].

2.2 Limitations

For playback in DP, video input resolution should match to DP's native resolution. This constraint is due to the support of the GUI. In the GUI case if we allow video source other than native resolution(by setting full screen overlay) then the graphics layer will disappear. To recover back GUI user need to kill and relaunch the GUI app. To avoid such condition TRD only supports video input resolution which is equal to DP's native resolution.
