| | | | | | MSVC requires an explicit cast from void * to void when applying the ternary conditional operator to switch between methods that return void.

* avfilter/af_astats: rework sample loopsMarton Balint2019-03-21
| | | | | | | 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>

* avfilter/af_astats: add support for selecting measured statisticsMarton Balint2019-03-21
| | | | | | | | | | | 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. Signed-off-by: Marton Balint <cus@passwd.hu>
