libswresample: move condition to start of loop. · 2c5c37ad


This avoids several issue like calculating sum/maxcoef
incorrectly due to adding up matrix entries that will
be overwritten, as well as out-of-range writes to
s->matrix if the maximum allowed number of channels is used.

Reimar Döffinger authored 10 years ago


A branch to avoid some calculation seems unlikely to have any benefits.

libswresample: Avoid needlessly large on-stack array. · 2231d5b6

Reimar Döffinger authored 10 years ago


We only actually need to use a tiny part of it.
Unfortunately we seem to have no real test coverage on
the code, so this is a bit risky.
