Marton Balint	6af67dcc35	avfilter/af_astats: add support for optimized min/max/peak calculation Signed-off-by: Marton Balint <cus@passwd.hu>	6 years ago
Marton Balint	5cc4b79b29	avfilter/af_astats: rework sample loops The channel loop is now the outer loop for both planar and interleaved. This is needed by the next patch, and the speed difference is negligable if any. Signed-off-by: Marton Balint <cus@passwd.hu>	6 years ago

Marton Balint	e85f37d51e	avfilter/af_astats: add support for selecting measured statistics set_metadata with many entries is not very efficient, and with small audio frames the performance loss is noticable. Also with this very simple calculations (like peak) can be even further optimized. Unfoturnately there are some small differences in metadata and av_log info output, so factorizing calculations and output might not worth the hassle.
