Ganesh Ajjanagadde	1bed09a30e	swresample: allow double precision beta value for the Kaiser window Kaiser windows inherently don't require beta to be an integer. This was an arbitrary restriction. Moreover, soxr does not require it, and in fact often estimates beta to a non-integral value. Thus, this patch allows greater flexibility for swresample clients. Micro version is updated.

wm4	80580bb240	swr: do not reject channel layouts that use channel 63 Channel layouts are essentially uint64_t, and every value is valid.	9 years ago
Ganesh Ajjanagadde	f3fc103c6a	doc/resampler, swresample/options: use proper capitalization Proper names should be capitalized in all user facing API as far as possible. The option names themselves have not been changed since: 1. We consistently keep option names in lower case. 2. Changing them would break existing scripts. 3. I suspect that we want to be similar to Sox and its relevant options. The converse is also true: improper names should not be capitalized generally.
