Hi All, I am working/testing a BananaPi M2M target based on Allwinner R16/A33 CPU for Video decoding especially 1080p. The target board has 512MB of RAM and I am using Linux Kernel 5.10.4.
I am using a MIPI DSI pipe line, the Panel is 800x480@60Hz with Pixel clock of 30MHz. I am playing Big_Buck_Bunny_1080_10s_1MB.mp4(which uses H.264). The video plays but stutters(observed a lag) on both MPV and VLC player. I have done a quick test with v4l2-request-test(based on https://linux-sunxi.org/Sunxi-Cedrus). The video used here is big_buck_bunny_1080p_MPEG2_MP2_25fps_6600K.MPG and it ran fine and uses the cedrus driver(https://pastebin.ubuntu.com/p/XSgVM8mgs8/). I am using parameters cma=256M drm_kms_helper.drm_leak_fbdev_smem=1 on kernel command line. Please advice/suggest on how can this stutter/lag be addressed and removed for H.264 1080p format video. Is the RAM size of 512MB a problem ?
