Sorry, I missed that EXTENSION is actually MAX/2 nowadays!
That's quite a lot, shouldn't this patch then make probetest fail?
MAX is not great for ASCII 64 bit IMHO, same for EXTENSION
with 32-bit ASCII, though it seems to at least pass probetest?
The ones I meant by "lazy" are the ones never returning more
than MAX/4 (and btw. I think the MAX/4 or EXTENSION/2 uses should all be replaced
with AVPROBE_SCORE_RETRY or AVPROBE_SCORE_STREAM_RETRY as appropriate).
Not all will be fixable, but the "lazy" demuxers are:
adp, eacdata, frmdec, icodec, tiertexseq
