CC: friendly ping @BKPepe @neheb @1715173329

I've fixed build and have tested on x86 - all goes well.

Missing dependency or unsupported platform?

[vooon]

@1715173329 hmm, i thought second patch from master should fix riscv64. MIPS most likely not supported.

New plugin which works with Video4Linux interface is arch dependant.

[vooon]

@1715173329 i've updated patch set to include RV64 PR and fix to build on MIPS 24k (non-mipsel).

[BKPepe]

So many patches, have you reached upstream repository about them? Would be nice to have them upstreamed.🙏

[vooon]

@BKPepe RV64 patches must be incorporated in AlexxIT/go2rtc#1651 (namely 3, 4 & 5).

Patch 2 is already in master, but it actually requires patch 6 too.
