Hi, this pair of commits adds cutoff support to libmp3lame, and documents the option "global" to lavc such that it is clear that it is *not* generally available.
Noted and requested in this thread: http://ffmpeg.org/pipermail/ffmpeg-user/2016-December/034703.html Testing: Encoded an MP3 without the patch, with the patch, and with the patch and a meaningful low cutoff value. Checked the spectrum using the showspectrum filter, and noted a significant cutoff. No proper frequency analysis done, just assuming libmp3lame does its thing correctly.
