Add the ability to download from file:// URLs. This requires the MPD manifest to specify an absolute BaseURL element at the MPD, Period or Representation level, or to use absolute URLS for all media segments.

Add support for the ffmpeg “concat demuxer” as a concatenation helper for multiperiod manifests, as an alternative to the existing ffmpeg “concat filter” support. To use this concatenation helper, all Periods must use the same encoding (same codecs, same time base, etc.), though they may be wrapped in different container formats. This concatenation helper is very fast because it copies the media streams, rather than reencoding them.

In a typical use case of a multi-period DASH manifest with DAI (where Periods containing advertising have been intermixed with Periods of content), for which it is possible to drop the advertising segments by using --minimum_period_duration or using an XSLT/XPath filter on Period elements, the content segments are likely to all use the same codecs and encoding parameters, so this concat helper should work well.

Use it with --concat-preference mp4:ffmpegdemuxer for example.

Fix an additional possible off-by-one error in calculating the segment count for $Time$-based SegmentTemplate manifests.

Fix duplicated merge of BaseURLS for video segments. Patch from @jonasgrosch.

Log additional diagnostics information when the verbosity level is greater than 0 or 1 for external commands run for muxing, concatenating, subtitle extraction/merging, and decrypting. The logged information includes the full commandline.

Fixed: the concatenation of multiperiod manifests using the ffmpeg concat filter was erroneously adding an empty audio track when none of the input Periods contained audio.
