* 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>
