about decode size limit

[amazingfate]

There are two locations defining decoder size limit: meson_options.txt and libv4l-rkmpp-dec.c. By default we use the values defined in meson.
But that is a global config overwriting all the decoders.
AV1 decoder on rk3588 supports 8K while the h264/h265 decoders support up to 4K. So why do we need global size limit defined in meson?

for old chips, there're some customers want to set limits in build scripts and based on chips

i think 3588 supports 8k h264/h265 too?

Got it. So just configuring meson_options.txt to 8K dec limit should be enough for rk3588. frmsize defined in libv4l-rkmpp-dec.c confused me.
