>mmap</code> are obviously the safest since they do not require any
parsing, but they can require humongous amounts of bandwidth (ie: tens
of Gbps for a 4K window). Older picture encodings like <code>png</code>
and <code>jpeg</code> are probably the safests due to their maturity.
Video encodings as well as newer picture encodings (often derived from
the new generation of video compression techniques, like
<code>webp</code> and <code>avif</code>) are probably less safe due to
their level of complexity - see
