This enables having multiple tracks of the same type which would
be treated as different things by the media server (as opposed to
different bit rate versions of the same track). According to the
smooth streaming specification, just setting the systemLanguage
tag is not enough to note that a track with the same attributes
differs from another one.

When user use the hls_wrap, there have many problem:
1. some platform refersh the old but usefull segment
2. CDN(Content Delivery Network) Deliver HLS not friendly
The hls_wrap is used to wrap segments for use little space,
now user can use hls_list_size and hls_flags delete_segments
instead it.

This way it's clear the size field accounts for the footer length plus every

The size field in the header/footer accounts for the entire APE tag
structure except the 32 bytes from header, for compatibility with
APEv1.

According to the spec[1], a value of 0 means the footer is present and a value
of 1 means it's absent, the exact opposite of header presence flag where 1
means present and 0 absent.
The reason for this is compatibility with APEv1 tags, where there's no header,
footer presence was mandatory for all files, and the flags field was a zeroed
reserved field.

Check value reduced as the code does not support larger lengths
Adds a `-hls_flags +temp_file` which will write segment data to
filename.tmp, and then rename to filename when the segment is complete.
This patch is similar in spirit to one used in Plex's ffmpeg fork, and
allows a transcoding webserver to ensure incomplete segment files are
never served up accidentally.

Blocks are marked as key frames whenever the "reference" field is
zero. This breaks for non-keyframe Blocks with a reference timestamp
of zero.
The likelihood of reference timestamp being zero is increased by a
longstanding bug in muxing that encodes reference timestamp as the
absolute time of the referenced frame (rather than relative to the
current Block timestamp, as described in MKV spec).
Now using INT64_MIN to denote "no reference".

Not starting a new segment if the elapsed microsecs since the start of the day
equals the the elapsed microsecs since the start of the day at the time of the
last cut seems plain wrong to me, Deti do you remember the original reason
behind this check?

The mov_stsc_index_valid() function is replaced with a macro to prevent
signdness issues (index is not always signed, and count is always

The comparison is also adjusted to reduce the risk of overflows.

Retain the ranges of frame indexes when applying edit list in
mov_fix_index. The index ranges are then used to keep track of the frame
index of the current sample. In case of a discontinuity in frame indexes
due to edit, update the auxiliary info position accordingly.

Allows the user to reserve space for the ODML master index. A sufficient
sized master index in the AVI header avoids storing follow-up master
indexes within the 'movi' data later. If the option is omitted or zero
the index size is estimated from output duration and bitrate.

Also removed an incorrect "align" var which wasn't used anyway (it was overwrittern).
Probably all/only .AT3 of frame size 98 are JS, too.
