从CPU占用率看明显是软解压，请问 如何才能让MPV实现硬解压播放？谢谢

主线内核的Armbian没有rkmpp。目前也无法实现mpv硬解播放。只有kodi可以，参考：[app] Kodi on armbian with hardware accelerating decode

在Armbian_22.05.3_Rock-3a_bullseye_edge_5.18.0.img系统下运行
boy@rock-3a:~$ kodi

在rock-3a-debian-buster-xfce4-arm64-20220311-0428-gpt.img系统下运行
rock@rock-3a:~$ kodi
libEGL warning: DRI2: failed to authenticate

从CPU占用率看还是软解压.在rock-3a-debian-buster-xfce4-arm64-20220311-0428-gpt系统中的表现比在Armbian_22.05.3_Rock-3a_bullseye_edge_5.18.0.img系统中差，CPU占用更高

1，需要编译支持v4l2-request的ffmpeg
2，需要编译kodi，使用编译参数-DAPP_RENDER_SYSTEM=gles
3，在wayland桌面环境下运行kodi-standalone --windowing=wayland
4，kodi界面中启用Allow using DRM PRIME decoder和 Allow hardware acceleration with DRM PRIME

“主线内核”没有，那么radxa提供的系统，用的那个修改版4.19内核有硬解码么？

有，可以用mpp，都是瑞芯微的方案，我没试过，应该是没问题的。

请问，这个rkmpp具体支持什么。哪里可以看到呢？我想知道支不支持硬编码
