This allows for wider compatibility with older devices, such as those
running iOS 3. The only difference between HLS version 2 and version 3 is
that version 3 supports non-integer EXTINF values, and as such, we can

The previous code expected a segment of type CLUT definition to exist
in order to accept a set of segments to be complete.
This was an incorrect assumption as the presence of a CLUT segment
is not mandatory.

Adding a new AVHWAccel also adds a new CONFIG variable for it
and said config variables are typically used to calculate the
size of stack arrays. In such a context, an undefined CONFIG
