The -hls_allow_cache parameter enables explicitly setting the
EXT-X-ALLOW-CACHE tag in the manifest file. That tag indicates
whether the client MAY or MUST NOT cache downloaded media
segments for later replay.

Valid values are 1 (=YES) or 0 (=NO) and the EXT-X-ALLOW-CACHE
will not show in the manifest for other values (or if
-hls_allow_cache is not used.

This is not merged as it does not work with musl here, while
our previous solution does.

See: 170e2fd7Merged-by: Michael Niedermayer <michaelni@gmx.at>

Support musl out of box.

Amend commit 9d2cee52 that got
wrongly merged in its stead.

After this the order from the original file is stored through readorder
when doing ffmpeg -i input.ass -c copy output.mkv.

And now that the ASS muxer honors the ReadOrder, extracting the ass back
(without transcoding) restores the original order.

This is more robust and should avoid false positives in coverity
That is if the type is ever mixed up, after this patch that would
just be a null pointer dereference instead of a random possibly
out of array access

Non-standard compliant libc should be supported on a per-case basis
anyway.

Data and subtitle streams might cause false positive.
