ISMV lacks any sort of edit list support, as well as tfxd is
effectively the PTS of the fragment for most intents and purposes.

Thus, if b-frames are requested without negative CTS offsets you
end up with N frames' worth of delay (tfxd PTS plus the CTS offset
of the first sample). Negative CTS offsets enable the first sample
to have CTS=DTS, and thus a/v desync due to b-frame reorder delay
is avoided.

Helpful in diagnosing latency issues.

This reverts commit 7e0df591.

"complete frames" containers, even if they don't need to assemble
packets, still depended on this code for proper packet duration and
timestamp generation.

If there is a saio/saiz in clear content, we shouldn't create the
encryption index if we don't already have one.  Otherwise it will
confuse the cenc_filter.

The changed method is also used for senc atoms, but they should not
appear in clear content.

Currently float are converted to 16b uint in input part
using src depth (32 bits) in hScale16To19 and hScale16to15,
make an invalid shift for the data

So shift the value when using float input
like 16 bpc uint.

Add fix a memory leak issue as James's comments.

This also fixes the behavior with HLS_TEMP_FILE to work correctly when
