Don't guess a timestamp of the start of the segment when running
in reverse mode, as more likely it means we're discontinuous somewhere
in the middle of the segment, and we'll fix up timestamps once
the frames are decoded and reversed.
When a PTS is not set, we still want to store the rest of the
buffer information, or else we lose important things like the
duration or buffer flags when parsing.
This adds a property to select the maximum number of threads to use for
conversion and scaling. During processing, each plane is split into
an equal number of consecutive lines that are then processed by each
thread.
During tests, this gave up to 1.8x speedup with 2 threads and up to 3.2x
speedup with 4 threads when converting e.g. 1080p to 4k in v210.

In gst_video_time_code_is_valid, also check for invalid
ranges when using drop-frame TC. Refactor some code which
broke after the check was added.

It was taking the initial input y-offset from the output value, which
only works for y=0 (in which case both are the same). If y > 0, we would
always stay behind the requested input offset and never ever read
anything from the input.
The parser might do some conversion on a stream but the stream keeps
being the same, and we need to make sure GstDiscoverer detects it is the
case.

There was already a check for that, but it failed because
subformat_guid[0] is a guint32 and that is then casted implicitely to a
guint16 when recursing... just that we checked the uncasted value.
This caused an infinite recursion and thus stack overflow.

Sometimes there is a human-oriented timecode that represents an
interval between two other timecodes. It corresponds to the human
perception of "add X hours" or "add X seconds" to a specific timecode,
taking drop-frame oddities into account. This interval-representing
timecode is now a GstVideoTimeCodeInterval. Also added function to add it to
a GstVideoTimeCode.

It is often usefull to make sure that you get a full copy of a profile.
For example you want to let the user modify it in the user interface
but still keep an unchanged version for later use.
API:
gst_encoding_profile_copy
Initialize min and max _get_property() to gets rid of these
compiler warnings:
gstappsrc.c:741:7: error: 'max' may be used uninitialized in this function
g_value_set_int64 (value, max);
^
gstappsrc.c:733:7: error: 'min' may be used uninitialized in this function
g_value_set_int64 (value, min);
^
Which happens because gcc doesn't know that GST_IS_APP_SRC will never
fail here.

This way special characters such as '@' can be used in
usernames or passwords, e.g.
rtsp://view:%40dm%4An@<IP-ADDR>/media/camera1
will now parse username and password into:
User: view
Pass: @dm:n

When parsing NUL-terminated strings, do not include the terminating
NUL byte(s). Depending on the encoding used, either g_utf8_validate()
failed due to this, or worse the call to g_utf16_to_utf8() would
return 0 items read on an empty string, causing it to fail parsing
certain frames.

Instead of enforcing the user to know and understand caps to describe
the encoding format, let him use element factory names directly.
This also makes it possible to ensure that a specific encodore/muxer
is used instead of letting the ranking system do it.
It is now possible to describe an encoding format simply specifying:
matroskamux:x264enc:vobisenc
Factor out functions in the parsing, cleaning up the whole thing.
Update documentation.
We used to only care about the name of the files even if the name
is defined in the encoding target serialized file.
That commit also allows user to define several names for a single
target file (using a ';' between the names) which allows us to have
a target for youtube that is called 'youtube;yt' or a target for
'ogg;ogv;oga' file extension.
We checked this already earlier, so this is dead code.
Leave an assert in place for consistency with the other
branch and in case the rest of the code changes.
CID 1397350.
The caps put into the stream topology by decodebin are the caps at the
moment the pads are exposed on it. This is usually before decoders
received any buffers.
In discoverer we however wait for pre-roll, which ensures that each
decoder handled buffers already. At this point, there might be more
information known about the caps already that we could make use of.
One example here is extra information stored in the SEI of H264, like
the multiview-mode. This will be known if there is a SEI before the
first keyframe, but decodebin won't put this into the topology as it
only waits for the initial caps of h264parse (which come directly after
SPS/PPS).
With this change, the multiview-mode is in the caps reported by
discoverer in many cases.
