f52fd7a68b video: Don't use extra plane and componenent for tile format 
Instead of using extra plane, we encode the number of tiles in x and y in the stride of
each planes (i.e. y_tiles << 16 | x_tiles) and introduce tile_mode, tile_width and
tile_height into GstVideoFormatInfo structure.

5b8e1925b5 videodecoder: use new segment earlier for reverse playback 
For reverse playback, the segment event will only be pushed when
the first buffer is actually pushed. But for decoding frames and storing
those into the list to be pushed the output_segment.rate value is used
to determine if it is forward or reverse playback.

In case a previous segment event (or none) is in use it will mistakenly
think it is doing forward playback and push the buffers immediatelly and
try to clip buffers based on an old segment (or an uninitialized one, leading
to an assertion)

This patch fixes this by copying the segment earlier if on reverse playback

27c1261c72 video-format: Document usage of GST_VIDEO_FORMAT_ENCODED 
This must only ever be used in caps in combination with a non-system
memory GstCapsFeatures, and where it does not make sense to specify

just document that it must not be used for capsfeature-less caps.

79ef75888c videodec/enc: clear reconfigure flag if negotiate succeeds 
So that it avoids to send an allocation query twice.
One from an early call to gst_video_encoder_negotiate from a

clearing the GST_PAD_FLAG_NEED_RECONFIGURE even on success.

cd52ff313e videodecoder: try to negotiate the buffer pool even though there is no o/p format 
We could have allocation query before caps event and even without caps inside
the query. In such cases , the downstream can return a bufferpool object with
out actually configuring it. This feature is helpful to negotiate the bufferpool
with out knowing the output video format. For eg: some hardware accelerated
decoders can interpret the o/p video format only after it finishes the decoding
of one buffer at least.

so will have to wait until the caller uses API that returns a GstFlowReturn,
for example when pushing this buffer.

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.

This allows elements to specify a function to upload

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.

with the first line of chroma samples and line 1 and 3 with the second line
