7b390a8bbd vpxenc: Add new bit-per-pixel property to select a better "default" bitrate
As part of this also change the default bitrate value to 0. The default
value was 256000 previously. In reality, if the property was not set the
bitrate value would be scaled according to the resolution which is not
very intuitive behavior. It is better to use 0 for this purpose. Now
together with newly introduced property "bits-per-pixel" 0 means to
assign the bitrate according to resolution/framerate.

The default bitrates are now
 - 1.2Mbps for VP8 720p@30fps
 - 0.8Mbps for VP9 720p@30fps
and scaled accordingly for different resolutions/framerates.

Previously the default bitrate was also not scaled according to the
framerate but only took the resolution into account.

This also fixes the side effect of setting bitrate to 0. Previously
encoder would not produce any data at all.

Addition from Sebastian Dröge <sebastian@centricular.com> to assume
30fps if no framerate is given in the caps instead of not calculating
any bitrate at all.

1b27badcfd videoencoders: use template subset check for accept-caps
It is faster than doing a query that propagates downstream and

0e10e92953 vp9enc: provide support for multiple pass cache files
Some files may provide different caps insight of one stream. Since
vp9enc support caps reinit, we should support cache reinit too.
If more then file cache file will be created, the naming will be:
cache cache.1 cache.2 ...

Based on patch by: Oleksij Rempel <linux@rempel-privat.de>

eb365cc3bb vp[89]enc: Don't set timebase from the framerate
The framerate very often is just an indication of the ideal framerate, not the
actual framerate of the stream. By just using the framerate, we confuse the
rate control algorithm algorithm as multiple frames will map to the same PTS
or have durations of 0.

51ebca3c03 vp{8,9}enc: Tell the encoder about actual timestamps and durations of frames
... instead of just counting frames. The values are supposed to be in timebase
units, not frame units. This fixes various quality problems with VP8/VP9
encoding and in general makes the encoder behave better.

Thanks to Nirbheek Chauhan for noticing this bug.

d0e8a385e0 vpx: mark arnr-type properties as deprecated and set them to no-op
ARNR type control in libvpx has been deprecated so this commit mark the
vp8enc and vp9enc associated properties as deprecated and change their
behavior to just display a warning message.
