I'm using Tinker Board (old one) with kernel `linux-image-current-rockchip`:

$ uname -a
Linux tinkerboard 5.8.18-rockchip #20.11 SMP PREEMPT Mon Nov 23 15:00:32 CET 2020 armv7l armv7l armv7l GNU/Linux

I builded libva with this script:
https://github.com/xmixahlx/pbp-tools/blob/073b0775b48d837103bc0cccde7435cc9900ff6c/pbp-install-libva
(with changes from `--libdir=/usr/local/lib/aarch64-linux-gnu` to `--libdir=/usr/local/lib/arm-linux-gnueabihf`)
Builded and installed without errors:

$ file /usr/local/lib/arm-linux-gnueabihf/libva.so.2.1000.0 
/usr/local/lib/arm-linux-gnueabihf/libva.so.2.1000.0: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[sha1]=432f2294306d050356ab992ab286af1ab16f0eac, not stripped


Then I builded libva-v4l2-request with this script:
https://github.com/xmixahlx/pbp-tools/blob/073b0775b48d837103bc0cccde7435cc9900ff6c/pbp-install-libva-v4l2-request
(with same changes from `--libdir=/usr/local/lib/aarch64-linux-gnu` to `--libdir=/usr/local/lib/arm-linux-gnueabihf`)
Builded and installed without errors:

$ file /usr/local/lib/arm-linux-gnueabihf/dri/v4l2_request_drv_video.so 
/usr/local/lib/arm-linux-gnueabihf/dri/v4l2_request_drv_video.so: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, BuildID[sha1]=4beee597e8643682867c9558e100e498c534f845, not stripped


Then I builded mvp with this commands:

$ git clone https://github.com/mpv-player/mpv-build.git
$ cd mpv-build
$ sudo apt-get install devscripts equivs fakeroot
$ mk-build-deps -s sudo -i
$ dpkg-buildpackage -uc -us -b -rfakeroot -j4


I got `mpv_2020.12.04.7c4465cefb_armhf.deb` and installed it.
vainfo looks ok, mpv linked with new compiled libva, but mpv gives me errors. How can I fix it? Did I need custom kernel patches to get h264 working with mpv?
