ffserver_config: cosmetic: move line_num into FFServerConfig

Moving line_num into FFServerConfig as parser state,
saves many passes of it aside of FFServerConfig pointer.

ffserver_config: cosmetic: simplify functions calls.

ffserver_save_avoption() and ffserver_opt_preset() have
redundant arguments. They can be obtained basing on media type.
This simplifies uses and reduce chance for a mistake.

movenc: Expose the fragment index as an avoption

Signed-off-by: Martin Storsjö <martin@martin.st>

movenc: Add a flag for indicating a discontinuous fragment

This allows creating a later mp4 fragment without sequentially
writing the earlier ones before (when called from a segmenter).

Normally when writing a fragmented mp4 file sequentially, the
first timestamps of a fragment are adjusted to match the
end of the previous fragment, to make sure the timestamp is the
same, even if it is calculated as the sum of previous fragment
durations. (And for the first packet in a file, the offset of
the first packet is written using an edit list.)

When writing an individual mp4 fragment discontinuously like this
(with potentially writing the earlier fragments separately later),
there's a risk of getting a gap in the timeline if the duration
field of the last packet in the previous fragment doesn't match up
with the start time of the next fragment.

Using this requires setting -avoid_negative_ts make_non_negative
(or -avoid_negative_ts 0).

lavf: Use wchar functions for filenames on windows for mkdir/rmdir/rename/unlink

This makes sure that the internal utf8 path names are handled
properly - the normal file handling functions assume path names
are in the native codepage, which isn't utf8.

This assumes that the tools outside of lavf don't use the mkdir
definition. (The tools don't do the same reading of command line
parameters as wchar either - they probably won't handle all possible

if no utf8/wchar conversion is involved.)

This is moved further down in os_support.h, since windows.h shouldn't
be included before winsock2.h, while io.h needs to be included before

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.

sidxindex: Write mimeType=audio/mp4 for audio-only representations

This fixes playback with dash.js, when the input is one separate
mp4 file per track.
