0c60f0daa4 video-chroma: add chroma resampler
Add functions to up/downsample chroma in horizontal and vertical
directions. These functions work in-placeand are meant to be used on the
input/output of the pack/unpack functions.

0c2c909497 video: Always provide a buffer in gst_video_(enc|dec)oder_allocate_output_buffer()
We have no way of tell the caller of the exact error (e.g. if we're flushing),
so will have to wait until the caller uses API that returns a GstFlowReturn,
for example when pushing this buffer.

f7db63f1b8 videoencoder: Try harder to push writable buffers downstream
For this release the corresponding GstVideoCodecFrame before
pushing the buffer. The buffer will now be writable unless
the subclass still holds another reference to the buffer or
the frame.

c3651a7905 videodecoder: always send the new buffer to parse functions
When we get a new buffer, always call the parse function, even if it is a 0
sized buffer. For theora we need to also decode 0 sized buffers.
Ideally we would like to make theoradec be packetized but that fails currently
because of oggdemux and because of the assumptions that the base class makes.

5f79a8cb93 videometa: API: Add GstVideoGLTextureUploadMeta
This allows elements to specify a function to upload
a buffer content to a specific OpenGL texture ID. It
could be used by the vaapi elements to provide a way
for eglglessink or WebKit to upload a VA surface to
an GL texture without the respective sinks knowing
anything about VA.

95266cf212 video-overlay-composition: fix ayuv/argb conversion
Helps when using dvbsuboverlay in connection with vaapisink
or some other video sink that wants ARGB pixels (dvbsuboverlay
attaches pixels in AYUV format, and we then convert as needed).

Alignment should not be a problem here.

31312d586e videodecoder: Don't blindly assign DTS to PTS
DTS and PTS usually have a non-zero offset between them in MPEG-TS,
so assigning DTS to PTS is almost always wrong.  The other, newer
timestamp recovery code does it correctly if we leave it as invalid.

ceb6585d26 videodecoder: warn if frame list gets long
Decoders that get unparsed input are internally leaking nearly
every incoming buffer.  This checks that case.

c1a25d2ce7 video-format: fix interlaced 4:2:0 and 4:1:0 pack/unpack
For interlaced vertically subsampled images we need to combine alternating
chroma lines with alternating luma lines. That is line 0 and 2 are combined
with the first line of chroma samples and line 1 and 3 with the second line
of chroma samples.

664adc6e19 gst-libs: use GST_*_1_0 environment variables everywhere
The _1_0 suffixed environment variables override the
non-suffixed ones, so if we're in an environment that
sets the _1_0 suffixed ones, such as jhbuild, we need
to set those to make sure ours actually always get
used.
