rkmpv fails on Debian 11

[DmitryMyadzelets]

I've updated Debian up to version number 11 (bullseye) on Rock64 , and now rkmpv which worked flawlessly before fails with the error:

mpv: symbol lookup error: /usr/lib/aarch64-linux-gnu/libSDL2-2.0.so.0: undefined symbol: gbm_bo_get_offset

> uname -a
Linux rock64 4.4.190-1233-rockchip-ayufan-gd3f1be0ed310 #1 SMP Wed Aug 28 08:59:34 UTC 2019 aarch64 GNU/Linux

To solve the problem I need some guidance from more experienced folks.

Trying to solve the problem I learnt a lot about shared objects, symbols and dependencies. Would share one quite profound article if you don't mind.

I've built ffmpeg and mpv from the source code (master branch), but they lack HW acceleration and even audio support for Rock64. Haven't yet figured out how it's been done by @ayufan.

My major concern is whether we need a special kernel for Rock64 at all. I've seen that rockchip RK3328 is already supported in the Linux kernel 5.3 (e.g. see this pull request). Can we just use this kernel and have all HW supported?

Please, leave a comment.
