Sorry for re-posting the patch twice. To send to the mailing list I had
to change the settings of my local postfix and made a mistake.
Anyway, just for convenience providing the list of changes since the
previous revision of the patch:

MediaCodec supports parameter "video-bitrate" to change the bitrate
on fly. This commit adds capability to use it.
It adds option -bitrate_ctrl_socket to the encoder which makes
the encoder to create an UNIX socket and listen for messages
to change the bitrate.
An example of ffmpeg execution:

Add external encoder VVenC for H266/VVC encoding.
Register new encoder libvvenc.
Add libvvenc to wrap the vvenc interface.
libvvenc implements encoder option: preset,qp,qpa,period,
passlogfile,stats,vvenc-params,level,tier.
Enable encoder by adding --enable-libvvenc in configu
This patch is based on the latest patchset from Thomas Siedel

I'm trying to write typo-detection bot. This is the only problem it noticed in
this patchset, but more nits incoming elsewhere.

Note1: when the EOF pts is not accurate enough, the last frame
can be dropped by vf_fps with default rounding.
Note2: vf_scale use framesync since e82a3997cdd6c0894869b33ba42430ac3,
so this is a very commonplace scenario.
For example:
./ffprobe -f lavfi testsrc=d=1,scale,fps -of flat \
-count_f
This a new ping but I post the patch again to get fate cleanly completed
on patchwork.
BTW, the initial design of framesync/EOF was in n3.4-dev-1799-g4e0e9ce2dc,
so one can say that time has past...
Thank you in advance for the review.
