Current mechanism of using AdaptationSet @group is not spec compliant.
The spec compliant mechanism is to use supplemental descriptor with

Three options are supported right now:
- reuse=1|0
Allow or disallow reusing UDP sockets. Default 0.
- interface=a.b.c.d
Address of the interface over which to receive UDP multicast
streams.
- timeout=microseconds
Timeout in microseconds. Default to unlimited.
A UDP url should be of the form udp://ip:port[?options], here
is an example:
udp://224.1.2.30:88?reuse=1&interface=10.11.12.13&timeout=12345
Also deprecate --udp_interface_address flag in favor udp options.

The original code accumulates sample durations in seconds (double)
and then generates new segment / cluster by comparing the accumulated
value with configured value.
There may be loss of precision when accumulating values in double.
For example, with a GOP of 96 frames and frame rate of 24 fps; the
accumulated frame duration for 96 frames is 3.999999999999, which is
very close to 4.0 but not 4.0. Problem would arise if segment
duration is set to 4. The created segments would have a duration of
8 seconds instead of 4 seconds.
The new code accumulates sample durations in uint64_t relative to
input time scale; the configured segment duration will be converted to
timescale for comparison. This avoids loss of precision.

Language tags can have subtags, such as "por-BR". While the base tag
should be 3 characters, the entire tag can be longer. Rather than
parse out the base tag and check that it is size 3 without the subtag,
we can just trust the ISO tag converter to do the right thing.
