this is somewhat a magic number, which can be understood from reading section "7.1.2 Exponent Strategy" of the ac3 specification, in short: Three exponents each represented as number 0-4 are grouped together and base-5 encoded, so the maximal correct value is 25*4 + 5*4 + 4 = 124.

Currently when using target_level with EAC3 it produces silence. This small patch fixes target_level for decoding EAC3. Example: ffmpeg -y -i /tmp/test.wav -acodec eac3 -dialnorm -14 -ac 6 -b:a 384000 /tmp/test.m2ts ffmpeg -y -target_level -24 -i /tmp/test.m2ts -acodec pcm_s16le -f matroska /tmp/out.mkv ffplay /tmp/out.mkv Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

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>
