Dne sreda, 29. september 2021 ob 18:04:39 CEST je Andrzej Pietrasiewicz napisal(a): > The G2 decoder block produces NV12 4x4 tiled format (NV12_4L4). > Enable the G2 post-processor block, in order to produce regular NV12. > > The logic in hantro_postproc.c is leveraged to take care of allocating > the extra buffers and configure the post-processor, which is > significantly simpler than the one on the G1. Quick summary of discussion on LibreELEC Slack: When using NV12 format on Allwinner H6 variant of G2 (needs some driver changes), I get frames out of order. If I use native NV12 tiled format, frames are ordered correctly. Currently I'm not sure if this is issue with my changes or is this general issue. I would be grateful if anyone can test frame order with and without postprocessing enabled on imx8. Take some dynamic video with a lot of short scenes. It's pretty obvious when frames are out of order. However, given that frames themself are correctly decoded and without postprocessing in right order, that shouldn't block merging previous patches. I tried few different videos and frames were all decoded correctly.
