[FFmpeg-devel] [PATCH] [Issue 632] AAC pulse data is applied incorrectly
Thu Sep 11 02:16:22 CEST 2008
This patch is pretty straight forward if you look at the relevant
section if 14496-3. Basically the pulse data should be applied to
match the sign of the underlying spectral coefficient (counting zero
as negative). While requantizing the spectral coefficient we must be
sure to not divide by zero.
Note: This does not fix all the problems with the stream in Issue 632;
there is still some bitstream decoding issue and possibly a TNS issue.
