libwavpackenc: remove libwavpackenc wrapper 
The manual states "there is virtually no reason to use that encoder.".

It supports less sample formats than the native encoder, is less efficient
than the native encoder and is also slower and pretty much remains untested.
libwavpack also isn't being fuzzed, which given that we plug the parameters
without any sanitizing them looks concerning.

Anton Khirnov 68918d3b7f lavu/buffer: add a convenience function for replacing buffers 
A common pattern e.g. in libavcodec is replacing/updating buffer
references: unref old one, ref new one. This function allows simplifying
such code and avoiding unnecessary refs+unrefs if the references are
already equivalent.

Gyan Doshi 1e5b3f77d9 avcodec/libopusenc: add option to set inband FEC 2020-09-09 11:40:06 +05:30
Nicolas George ddba05afe4 lavfi/vsrc_testsrc: switch to activate. 
Allow to set the EOF timestamp.

Also: doc/filters/testsrc*: specify the rounding of the duration option.

The changes in the ref files are right.

For filter-fps-down, the graph is testsrc2=r=7:d=3.5,fps=3.
3.5=24.5/7, so the EOF of testsrc2 will have PTS 25/7.
25/7=(10+5/7)/3, so the EOF PTS for fps should be 11/7,
and the output should contain a frame at PTS 10.

For filter-fps-up, the graph is testsrc2=r=3:d=2,fps=7,
for filter-fps-up-round-down and filter-fps-up-round-up
it is the same with explicit rounding options.
But there is no rounding: testsrc2 produces exactly 6 frames
and 2 seconds, fps converts it into exactly 14 frames.

The tests should probably be adjusted to restore them to
a useful coverage.
