It will overflow if somebody keeps streaming for a time long enough.

start_time is in stream timebase units while end_time is
in AV_TIME_BASE ones.

recording_time is in AV_TIME_BASE units.

Consider the corner case with a list size larger than the wrap
number.

Avoid calling av_get_frame_filename twice, once to generate the
segment filename and once to generate the playlist.

The segment path is desumed from the playlist path, recording a
relative path in the playlist while serving the file could lead
to misleading results.

Thread safe version of the common basename and dirname.

Also fixes linking in various configs with only individual parts enabled
because the RTP muxer chaining code depends on the general RTP code,
which is now accounted for.

This option disables all programs, libraries and other parts of Libav
that get built as part of the compilation process.

Fixes decoding of 9/10 bit per pixel h264 videos as reported in
https://bugzilla.libav.org/show_bug.cgi?id=404 .

This function used to be shared with the xxan decoder, but that is not
true anymore.

The background changes from 128 (used by the default/cmdutils
get_buffer()) to 0. This looks more correct.

Do not overwrite linesize set by get_buffer().

The last frame in the FATE test is not decoded anymore, since the file
is cut and a part of it is missing.

If s->filename doesn't contain any period/filename extension to strip
away, the buffer will be too small to fit both strings. This isn't
any buffer overflow since the concatenation uses av_strlcat with
the right buffer size.

The description as updated in 6e5c44b0f made it sound like it is
handled exactly like the pts, which it is not. Clarify that it
is the packet that triggered returning the frame instead of just
the last avpacket (in case of frame threading, it won't be the
dts of the last packet).

Building libavfilter without that functionality makes little sense.

Also move mpegvideo_select statement to the correct position.

Remove some pointless comments and empty lines.
