If we're in continuous mode where we'll play the entire CD from
start to finish, send a TOC event downstream so any downstream
muxers can write a TOC to indicate where the various tracks
start and end.
The DATE field may contain dates, partial dates, or dates with
time. Store the result in GST_TAG_DATE_TIME, so we can express
properly which fields are present or not, and can store the
time if there is one, and can serialise and deserialise the
tag without loss of information and without making up
information that's not there.
Instead of using short YYYY-MM-DD form we will store
long YYYY-MM-DDTHH:MM:SS+TS date and time.
According to this documentation we can do it:
http://wiki.xiph.org/VorbisComment#Date_and_time
This datetime format is needed by apps where more information
is needed. For example voice, meeting recording, etc.

Check that we have a valid output_state before attempting to use it to calculate
the duration of a buffer. It is possible that we don't have a state yet, for
example when we are dropping the first buffers.
Make sure the frame deadline was set before calculating the
max_decode_time. Fixes problems with ffmpeg skipping frames when
it doesn't need to, when the input doesn't have full timestamping
(divx in avi)
Interpolating the timestamps from the picture numbers
does more harm than good, getting it wrong in a lot of
cases (especially reverse playback). Removing it in favour
of simply incrementing the timestamps until there's
something better
Use g_list_free_full instead of walking lists twice when freeing
them.
Remove pointless clause in gst_video_decoder_chain that doesn't
actually have any effect.
Other changes to make the code slightly more like the 0.11
version.
Move processing of the gather list into the flush_parse function.
Add a last ditch attempt to apply timestamps to outgoing buffers
when walking backwards through decoded frames. Requires that each
gathered region has at least one timestamp.
Make sure to remove decoded packets from the decode list when
they are sent - otherwise the list just grows on each cycle, with
more and more frames being decoded and then clipped away.
Break out of the processing loop early on a bad flow return to make
seeking more responsive.
Use the gst_video_decoder_clip_and_push_buf function in reverse
mode, instead of pushing all buffers arbitrarily.
A couple of small efficiency gains in the list handling, by moving
list elements directly and not reallocating, and by reversing
and concatenating the gather list instead of moving it one node
at a time.
Rename the gst_video_decoder_do_finish_frame function to
gst_video_decoder_release_frame.
Rename gst_video_decoder_have_frame_2 to
gst_video_decoder_decode_frame and pass the frame to process
directly, rather than using the current_frame pointer as a holding
pen.
Move the negative rate handling out of the function to where it
is needed, and remove the process flag.
The frames are the owners of the buffers. In cases where a decoder
would keep around reference frames, we need to ensure they don't
disappear early.
To handle this, we pass downstream a complete sub-buffer of the output
buffer, ensuring that the buffer will only be released when downstream
is done with it *AND* the frame is no longer used.

Don't replace the initial frame's timestamp with a bogus
one calculated from the (incorrect for Ogg) frame number just
because the 'sync time' hasn't changed.
Also, don't output a bogus warning about the output_frame being
NULL when it's being dropped/skipped due to QoS.
Use a separate variable to describe the amount of lines that will be used in
packing instead of abusing the h_sub variable. Some formats might have no
subsampling but need to operate on multipe lines.
RGB8_PALETTED -> RGB8P
Fix the definition of paletted formats, store the palette in the second
plane.
Make sure we copy the palette correctly in gst_video_frame_copy()
Don't do alignment on the palette in videopool
Remove Y800 and Y16 wich are the same as GRAY8 and GRAY16_LE
Add const to the GstVideoFormatInfo when used in argument
Add GRAY8 and GRAY16 pack/unpack functions
Add support for supporting chroma subsampling correctly in the pack
function.
Fill in the pack and unpack functions for most formats.
Add some missing pack/unpack functions to the orc file.
Add a flag argument to the pack and unpack function so that we can expand it
later when needed. We could for example prefer a High Quality pack/unpack
operation later.

Add 10 bits I420 format definitions
Move encoded format as second entry in the array so that it doesn't end up in a
weird place when we add formats.

DTS type I-III specify the burst length in bits. Only type IV (which we
do not currently support) needs it to be specified in bytes. Thanks to
Julien Moutte for pointing this out.
When closing the connection, unref the currently used sockets. This should close
them when not in use. We need to do this because else we cannot reconnect
anymore after a close, the connect function requires that the sockets are NULL.
Clear the GError after g_socket_connect tells us that the connection is pending.
If we don't do this, glib complains when we try to reuse the non-NULL GError
variable a little below.
They're hardly used, and probably more confusing than anything
else, and it's not clear that anyone would really need to be
able to tell them apart at the media type level.
This makes sure that we wait until we received all tags for the
subtitle streams and have all information that is collected by
the discoverer.
Fixes bug #673504.
When need to push out all the previously received events, concatenate all the
events from the previous frames (instead of leaking the old ones)
Improve debugging a little

Frames receive a refcount when added to the frames list so release that refcount
in gst_video_decoder_do_finish_frame(). Also release the ref on the frame
because gst_video_decoder_do_finish_frame() takes ownership of the passed frame.
This allows subclasses to override it, as is necessary for e.g. the
video-crop meta. It is now necessary that after decide_allocation()
there is always a allocator and a configured buffer pool inside the
query.
Video base classes and theora plugin still needs to be ported again

Some container formats (like AVI) set DTS on the buffers instead of
PTS.
We detect this by:
* detecting if input timestamps are non-increasing
* detecting if the order the frames come out is the same as the order
they were inputted (meaning the implementation is reordering frames).
If the decoder reorders frames, but input buffer timestamps were not
reordered, that means the buffers has DTS and not PTS as their timestamp.
If this is the case, we use set the PTS of the outgoing frames in the
same order as they were given to the decoder.
This fixes the issue for any decoder using this base class (yay).
