This allows storing the .ismv/.isma/.ismc files separately from
the .ism file on a server, without having to manually edit the
.ism file after generating it with the ismindex tool.

This typo has existed since this code was added in c1658257.
Newer versions of clang pointed out that this comparison always
was true (since the result of the negation is either 0 or 1, while
AVDISCARD_ALL has the value 48).

default-base-is-moof shall be set to track fragments compatible with DASH
Media Segments. So, this is a fundamental support for ISOBMFF ver. DASH.
This is meaningful only when base-data-offset-present is absent and two or
more track fragments are present in a movie fragment.

This obviates a dependency of the LJPEG encoder on mpegvideo.

Add ability to handle multiple palettes and objects simultaneously.
Each simultaneous object is given its own AVSubtitleRect.
Note that there can be up to 64 currently valid objects, but only
2 at any one time can be "presented".

When running on a 64 bit kernel, /proc/cpuinfo lists different
optional features than on 32 bit kernels (because some of them
are mandatory in the 64 bit implemenations).

The kernel does list the old features properly if they are queried
via /proc/self/auxv though - however this file is not always readable
(e.g. on most android systems). The getauxval function could also
provide the same info as /proc/self/auxv even if this file isn't
readable, but this function is not always available (and thus would
need to be loaded with dlsym for compatibility with older android
versions).

The android cpufeatures library does this slightly differently,
by assuming that these are available if the "CPU architecture"
line is >= 8, see [1] for details.

It has been suggested to include the old, non-optional features in
/proc/cpuinfo as well, but that suggested patch never was merged.
See [2] for the discussion around this suggestion.

This will come in handy during dsputil splitting.

Properly generate pts for the frames sent to the encoder, avoid
using private and deprecated AVStream.pts.

It makes more sense to print the timebase exactly as it is set. Also,
this avoids a divide by zero when av_dump_format() is called on a format
context before writing the header.

With optimzations disabled compilers have trouble doing dead code
elimination on 'if (foo && 0)' expressions, while 'if (0 && foo)'
still works, so use the latter to avoid problems.

Bug-Id: 707

The JPEG spec requires it to be this.
