a724f9ddfb encodebin: Ensure that a single segment is pushed into encoders
Following the [design document] encodebin needs to handle sources that
output multiple streams, for that purpose and to make it simpler,
we ensure that a single segment is outputted to the encoders by using
an `identity single-segment=true` at the beginning of streams chains.

Added API to enable or disable the use of that new feature.
Added support for the encoding profile parser for that new property,
keeping backward compatibility

6be312a759 encoding-profile: set_restriction should accept null as valid
It was checking for GST_IS_CAPS only and that would fail if the new
restriction caps was NULL and its documentation says it accepts NULL as
valid input.

77b23ea0ac encoding-profile: Fix deserialization of a single profile
Instead of trying to guess what profile to build, just get the possible
elements to use with the specified caps and determine the
EncodingProfile from it.

59eacaa966 encoding-profile: Handle escaped '\:' in caps describing profiles
Otherwise it won't be possible to specify some profiles such as

    video/x-h264,profile=(string)high-4:4:4

With this patch, we can do

    video/x-h264,profile=(string)high-4\:4\:4

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.

48324cab38 encoding-profile: Remove some more fields from the caps when creating from discoverer info
parsed, framed, stream-format and alignment are only relevant for parsers and
should not matter here. We still want to be able to use an encoder that can
only output byte-stream if the input was avc.

If we e.g. have AVI with DV container with video/audio inside the DV
container, we can't handle this at this point with an encoding profile.
Instead of erroring out, flatten the container hierarchy.

fc99a61774 encoding-profile: Remove codec_data and streamheader fields from constraint caps
When converting discoverer output to an encoding profile, it makes sense to
omit these. It's very very unlikely that our encoder is going to produce bit
by bit the same codec_data or streamheader.

f31240a765 encoding-profile: Don't use preset_name string after free
When we run the loop for another time and do not have a preset name, we would
try to print the preset name of a previous iteration that is already freed.

Also move some other variables into the block where they are actually used
to prevent similar mistakes in the future.

72c05d1cbb encodebin: Add a way to disable caps renegotiation for output stream format
In some cases, the user might want the stream outputted by encodebin to
be in the exact same format during all the stream. We should let the
user specify when this is the case. This commit add some API in the
GstEncodingProfile to determine whether the format can be renegotiated
after the encoding started or not.

API:
    gst_encoding_profile_set_allow_dynamic_output
    gst_encoding_profile_get_allow_dynamic_output
