Using the first names of authors sounds somewhat unprofessional
and might be considered offensive which is not intended.
The new names use the initials of the authors due to simplicity
and the possibility to apply it consistently without the need
to find political correct names for each future case where
alternative codecs might exist. Also its shorter ...

If someone has a better idea, like maybe 2 random letters
and people prefer it then iam happy to switch to that ...

This filter is not required anymore with aformat. Drop it at next bump.

This is heavily based on 2831b307 by Anton Khirnov <anton@khirnov.net>

In particular, show h value in degrees.

This also drops support for "flat syntax" and "reinit" command.

"reinit" command is not very robust and complicates the logic more than
necessary, since requires to reset all the options in the command.

*This is a syntax break*.

We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

lavfi should never modify the filter through that pointer.

Fixes an overflow of the sample count field within the audio stream header
chunk if audio stream data exceeds 2GB.

Similar to 937325f3.

The ',' separator is deprecated with aformat, and thus causes various
arnings when transcoding audio.
