This reverts commit 9d753824.

If the DVD subpicture caps are not part of the raw caps, uridecodebin
doesn't qualify resindvdbin as raw source and plugs decodebins, which
causes broken DVD playback because of bugs elsewhere.

This change was originally added to only expose supported, raw subtitles,
e.g. if the subtitle sink did not support DVD subpictures but a converter
to some supported format exists. It's not very important right now because
we have nothing (that is autoplugged) to convert from plaintext/pango-markup
or DVD subpictures to something else.

Otherwise the uridecodebin will be still a child of playbin2 and
its signals will still be connected. In future state changes this
will then emit unrelated signals that will confuse playbin2 or,
even worse, cause crashes and assertions.

If the source element failed here, oggdemux would crash.

Fixes #623218.

On special request. Because it's important, apparently.

For maintainability reasons and $(builddir).

Fixes #622944.

We depend on GTK+ >= 2.14 already.

If an error happens, the PAUSED state will never be reached. If an
application re-uses decodebin2 (like totem) where one would normally
set to READY between each file, the cleanup that normally happens in
the PAUSED=>READY codepath will never be called, resulting in the
following file to re-use the previous demuxer/decoder/...

There's no need to run a main loop, add a bus watch and deal with
helper structs here just to wait for an EOS message.

Use new gst_element_link_pads_full() function to link elements,
and disable all checks when linking (don't try this at home).

Down to 18s from 3m20s. Scary.

Check for the state of the ringbuffer before doing the checks of the other
buffer properties, when we're not started, we don't care about those values.

Speeds up caps nego 2 fold

Fixes unused variable warning in that case.

These are currently being marked as audio/x-m4a which is incorrect.

Only want to load core/-base plugins here.

Use %s for strings, not %d.

Previously we would read behind the end of the source lines.

Adds GST_TAG_IMAGE_ORIENTATION mapping to xmp helper lib.
Tests included.

Adds GST_TAG_IMAGE_ORIENTATION to the exif helper lib mapped tags.
Tests included.

We need to clear the pointer to our ts-offset element when we destroy the video
chain elements to make sure nobody derefs it to invalid memory afterwards.
