fe42f94ce1 dashenc: Don't segment all video streams when one stream gets a keyframe
This makes sure that segments actually start at a keyframe (and
makes sure we don't split segments twice in a row, with one segment
consisting of only a handful of packets), when one stream uses b-frames
while another one doesn't.

f856d9c2f3 dashenc: Don't require the stream bitrate to be known
Don't write any bitrate attribute if it isn't known. As long as one
doesn't want automatic bitrate switching, playback can work just
fine even if it isn't set.

If strict standard compliance is requested, this is still considered
an error, since the attribute is mandatory according to the spec.

Based on a patch by Rodger Combs.

5f8fcdd448 dashenc: degrade gracefully if a stream's bitrate is unavailable
If a stream's bitrate is not set, this attempts to use its rc_max_rate;
if neither is set, it avoids writing a bandwidth attribute at all.

fe5e6e34c0 lavf: Add an MPEG-DASH ISOFF segmenting muxer
This is mostly to serve as a reference example on how to segment
the output from the mp4 muxer, capable of writing the segment
list in four different ways:
- SegmentTemplate with SegmentTimeline
- SegmentTemplate with implicit segments
- SegmentList with individual files
- SegmentList with one single file per track, and byte ranges

The muxer is able to serve live content (with optional windowing)
or create a static segmented MPD.

In advanced cases, users will probably want to do the segmenting
in their own application code.
