Michael Niedermayer 82bf8c8783 hls: Copy the time base from the chained demuxer
When a variant stream isn't mpegts but e.g. raw adts, the
default time base (90k) isn't correct.

Martin Storsjö eb33ba04e0 hls: Return all packets from a previous variant before moving on to the next one
This serves as a safeguard; normally we want to use the dts
comparison to interleave packets from all active variants. If that
dts comparison for some reason doesn't work as intended, make sure
that all packets in all variants for a certain sequence number have
been returned before moving on to the next one.

This avoids breaking some slightly incorrect (dts > pts) timestamps

Hendrik Leppkes 779e6c2b98 lavfi: add attribute_align_arg to all public entry points
Previously it was partly only added to central functions called
internally, however if GCC would inline these into the public fuction, the
alignment attribute would not take effect.

Instead, add it to all public entry points to avoid these problems.

Martin Storsjö 54ba52077c arm: Comment out unused labels in simple_idct_arm
When building for iOS in thumb mode, gas-preprocessor.pl doesn't
mark unused labels as thumb functions (as it does for other
local labels, where it can figure out that they are functions
due to being referenced in branch instructions). This leads to
linker warnings for some of those local labels, such as:

ld: warning: ARM function not 4-byte aligned: __a_evaluation from
libavcodec/libavcodec.a(simple_idct_arm.o)

Therefore, comment them out since they don't have any function.
They do still have a value in documenting key points in the
assembly source though.

This enables the use of much larger input arrays, which
