Most of our VP56 optimizations are VP6-only and will stay that way.
So avoid compiling them for VP5-only builds.

QuickTime will play multiple audio tracks concurrently if this flag is
set for multiple audio tracks.  And if no subtitle track has this flag
set, QuickTime will show no subtitles in the subtitle menu.

This can be useful for decoding AAC object types that are not supported
by the native AAC decoder, e.g. AAC-LD and AAC-ELD.

This allows for dropping or duplication to match a particular start time.

This allows creation of frame accurate chapter marks from sources
like DVD and BD where the precise chapter location is not known until
the chapter mark has been reached during reading.

Do not segfault when writing tracks such as tmcd by writing them down
as generic DataHandlers if not known.

Prevent an assert.

Data streams have a defined timebase, do not ignore it.

Allow emitting the current cluster that is being written before
starting a new one, simplifying how to figure out where clusters
are positioned in the output stream (for live streaming).

Seeking in certain broken files would cause ogg_read_timestamp
to fail because ogg_packet would go into a state where all packets
of stream 1 would be discarded until the end of the stream.

The mov/mp4 muxer has support for handling negative timestamps
via edit lists (which customarily is used for handling the 1-frame
delay due to B-frames as well).

Using the muxer's native way of handling it is better than using
the generic offsetting. The generic offsetting is a bit too
crude when e.g. the timebase of one track is 1/fps, where the
edit lists can handle it accurately.

Implicit vector loads on POWER7 hardware can use the VSX

The hls muxer itself doesn't have any direct (object file level)
dependencies on mpegtsenc.o, and including that object file
directly doesn't ensure that it is registered so that the muxer
actually is accessible.
