Add new required elements and constrain presence and values for existing
ones based on the spec.
Signed-off-by: James Almer <jamrial@gmail.com>

In combination with the streaming option it constrains the value of a few elements,
to prevet clients from buffering too much data before starting presentation.

Implemented as as a frag_duration muxer option and key=value entry in the
adaptation_sets muxer option. It has the same syntax as the seg_duration option.
A new frag_type option is also introduced to select the kind of fragmentation.

Implemented as as a seg_duration key=value entry in the adaptation_sets muxer
option.
It has the same syntax as the global seg_duration option, and has precedence
over it if set.

Revert regression introduced in 6af050d7

Width and height expressions in scale and scale2ref filters can now
reference frame index, timestamp and packet position.

Allows finer identification and logging of invalid expressions and use
of a single list for symbols and their index for both scale and
scale2ref.

Retains parsed expressions which allows for better
error-checking and adding animation support.

Needed when filtergraph reinit is disabled for the ref input.

Better readability and allows reuse

Since bae8844e, the packet is automatically unreferenced in
ff_read_packet() when an error is returned; but the documentation of
this of AVInputFormat.read_packet has not been updated accordingly.

The current code only checks when writing the trailer whether the video
format and Codec ID are actually compatible with the container. At this
point, a lot of data will already have been written (in vain, of
course), so check during the init function instead.

nonsense. So postpone this check.
