I think the min/max width/height are incorrect. From rockchip's TRM V1.0
Part1 page 374, supported image size is 64x64 to 65472x65472. And my
chromium can't use rkvdec2 because min width/height are set to 16, which
will cause error at here in rkvdec2_h264_validate_sps:

width is 16, height is 32 while ctx->coded_fmt.fmt.pix_mp.width and
ctx->coded_fmt.fmt.pix_mp.height are both 16.

After changing them to 64 my chromium can use rkvdec2 to decode h264
videos now.

Anyway many thanks to your amazing work!
