LDR with register offset and PC as base register is not available in
the Thumb instruction set so the addition must be done separately.

Make it consistent with the other function-like macros.

Allow extensibility.

Option for Voice Activity Detection is added to speex encoder.

Speex detects non-speech periods and encodes them with just enough bits
to reproduce the background noise, aka ``comfort noise generation''.

While a 25 fps stream can in general store frame durations in 1/25
units, this is not true for the timestamps. For example a 25fps
and a 25000/1001 fps stream when they are stored together might have
a matching 0 timestamp point but when for example a chapter from
this is cut the new start is no longer aligned. The issue gets
MUCH worse when the streams are lower fps, like 1 or 2 fps.

This commit thus makes the muxer choose a multiple of the
framerate as timebase that is at least about 20 micro seconds precise

With this, when we use a finer timebase than neccessary to store
durations the demuxer still knows what the original timebase was.

This way audio frames can be exactly stored even when they are not

Silence a GCC warning. A leftover of the disabled version is still

This needs to be accessible for libavfilter in the next commit.

Split away option settings, sanity checks and general setup.

Mostly cosmetic changes adding some intermediate to shorten the lines.

This takes into account planar vs. packed when comparing to find the closest
sample format match.
