| | | | | | | | | | | to showwavespic by name The 'sqrt' and 'cbrt' scalers were added in commit 80262d8c86e94ff9a4bb3a9e3c2d734e04ccb399, but their symbolic option values only made available to the showwaves filter, not showwavespic, despite the scalers working properly by their numerical option values.

* lavfi/loudnorm: add an internal libebur128 libraryMarton Balint2016-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also contains the following changes to the library: - add ff_ prefix to functions - remove cplusplus defines. - add FF_ prefix to contants and some structs - remove true peak calculation feature, since it uses its own resampler, and af_loudnorm does not need it. - remove version info and some fprintf(stderr) functions - convert to use av_malloc - always use histogram mode for LRA calculation, otherwise LRA data is slowly consuming memory making af_loudnorm unfit for 24/7 operation. It also uses a BSD style linked list implementation which is probably not available on all platforms. So let's just remove the classic mode which not uses histogram. - add ff_thread_once for calculating static histogram tables - convert some functions to void which cannot fail - remove intrinsics and some unused headers - add support for planar audio - remove channel / sample rate changer function, in ffmpeg usually we simply alloc a new context - convert some static variables to defines - declare static histogram variables as aligned - convert some initalizations to mallocz - add window size parameter to init function and remove window size setter function - convert return codes to AVERROR - fix indentation Signed-off-by: Marton Balint <cus@passwd.hu>

* lavfi/sidedata: add filter for manipulating frame side dataMarton Balint2016-10-13
| | | | | | | | | | | This is a similar filter to f_metadata, only it works on side data. Since adding side data from a user provided arbitrary binary string is unsafe, because current code assumes that a side data of a certain kind has the proper size, this filter only implements selection and deletion. Also, no value matching support is implemented yet, because there is no uniform way to specify a side data textually. Signed-off-by: Marton Balint <cus@passwd.hu>
