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.
