This is intending to fix the case described in https://lists.ffmpeg.org/archives/list/ffmpeg-devel@ffmpeg.org/thread/AAZ7GJPPUJI5SCVTDGJ6QL7UUEP56WOM/ Where FCBParam optim is used uninitialized a min_err of 1<<30, allows the struct to be never initilialized as all err (which is int32_t) can be larger than min_err. By increasing min_err above the int32_t range this is no longer possible Untested, as i do not have the testcase Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>i
