ef55c8a6b7 riff-media: Don't recurse in for nested WAVEFORMATEX
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.

629e8229a7 videotimecode: New GstVideoTimeCodeInterval type, ability to add to a GstVideoTimeCode
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.

57ff3ea72f appsrc: fix compiler warning
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.

cd101ce8f0 id3v2: fix splitting strings in ISO-8859-1 and UTF-16 formats
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.

51cd2bd926 encoding-profile: Allow using factory names in serialization format
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.

85979f996d encoding-target: Allow using name and targets from serialized file
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.

15123c0455 discoverer: Get caps from the element's srcpad if possible
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.

010b9547d3 audio-converter: optimize endian conversion
Optimize LE<->BE conversion by adding a dedicated fast path instead of
using the generic converter. Implement transform_ip function in order to do the
endian swap in place.

This saves buffer allocation for the intermediate format, can be done in place
and also performs the conversion in one step instead of unpack-convert-pack.

For all bit widths the naive algorithm is implemented, which provides the best
performance when compiled with -O3. ORC was considered but eventually removed
as it requires a dedicated function for in-place conversion (due to the
"restrict" parameters).

A more complex algorithm for the 24-bit conversion with unrolled loop and
32-bit processing is implemented in the #if 0 section. It performs better if
compiled with -O2. With -O3 however the naive algorithm performs better.
