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.

Otherwise we would end up with a bogus ->audiochain->ts_offset field
which would cause segfaults/assertions when trying to modify the
'ts-offset' property in update_av_offset().

Was easy to trigger when using a list of audio+video files mixed with
video-only files in totem.

Use _peek_string_index instead of _get_string_index to avoid
a string copy

In buffer_alloc, if the buffer caps are new, call
gst_pad_peer_accept_caps once only, it's useless to call it in the
cases where we know it will always fail.

Fixes bug #621190

Update common for latest gstdoc-scangobj and inspect xml files for
escaping and pad template order changes. Update other gtk-doc files
for API additions and object hierarchy changes.

Use the pad caps when they are available to continue the autoplugging. If the
pad caps are set, they are fixed and then we can directly continue autoplugging.
