Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk

Add stereo rematrixing support to the AC-3 encoders. This improves the audio quality significantly for stereo source with both the fixed-point and floating-point AC-3 encoders.

ac3enc: add channel coupling support Channel coupling is an optional AC-3 feature that increases quality by combining high frequency information from multiple channels into a single channel. The per-channel high frequency information is sent with less accuracy in both the frequency and time domains. This allows more bits to be used for lower frequencies while preserving enough information to reconstruct the high frequencies.

avcodec/ac3: always use hardcoded tables The table in question is a 253 byte one. In fact, it turns out that dynamic generation of the table results in an increased binary size. Code compiled with GCC 5.2.0, x86-64 (size in bytes), before and after patch: old: 62321064 libavcodec/libavcodec.so.57 new: 62320536 libavcodec/libavcodec.so.57 Thus, it always make sense to statically allocate this. Tested with FATE with/without --enable-hardcoded-tables. Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
