cargo-c will produce a pkg-config file making it easier to statically
link plugins.
Also add 'static' features for plugins depending on < 1.14 as this is the
minimal required version to use static linking because of ABI changes in
core.
There is no way to dynamically ask Cargo to build static or dynamic lib
so we have to build both and pick the one we care when doing the meson
processing.
Fix#88
The audiornnoise element can be used as playbin audio-filter for instance, to
suppress noise in the audio stream.
This plugin relies on the nnnoiseless crate which implements the noise removal
algorithm of the Xiph RNNoise library, in Rust. Some demos and documentation of
the RNNoise C library can be found on:
https://people.xiph.org/~jm/demo/rnnoise/Fixes#114
Only two uses of unsafely setting the pad functions is left:
- fallbacksrc for overriding the chain function of the proxy pad of a
ghost pad
- threadshare for overriding the pad functions after creationg, which
probably needs some fixing at some point
