cd309f31a0 vp9dec: Add warnings for unsupported frame formats 
At least output an element warning on the bus when we
encounter a frame format GStreamer doesn't currently support.

This also remove copies for VP8, which was not correctly in place
in previous related patch.

189c291805 vpxdec: Use GstMemory to avoid copies 
With the VPX decoders it's not simple to use downstream buffer pool,
because we don't know the image size and alignment when buffers get
allocated. We can though use GstAllocator (for downstream, or the system
allocator) to avoid a copy before pushing if downstream supports
GstVideoMeta. This would still cause a copy for sink that requires
specialized memory and does not have a GstAllocator for that, though
it will greatly improve performance for sink like glimagesink and
cluttersink. To avoid allocating for every buffer, we also use a
internal buffer pool.

b848c1b6ff vpxdec: Use threads on multi-core systems 
This adds an automatic mode to the threads property of vpxdec in order to
use as many threads as there is CPU on the platform. This brings back
GStreamer VPX decoding performance closer to what is achieved by other
players, including Chromium.

2e412a447a docs: update example pipelines in element docs 
Mostly gst-launch -> gst-launch-1.0
Use autovideosink/autoaudiosink more often.
Sprinkle some converters here and there.

501a53b26d vpxdec: Fix calculation of width in bytes 
Right now we only support I420, but vpx seems to support more formats.
This will prevent hard to find bug in the future.

9eb22a533b vp9dec: Get input width/height from the codec instead of the input caps 
They are reported properly by libvpx if the correct struct members are used.
This also fixes handling of resolution changes without input caps changes.
