Nikolas Bowe	96cd6f672e	avcodec/(e)ac3: Fix target_level for EAC3. 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>	8 years ago

Tim Walker	33275a0de0	ac3dec: change logging of skipped E-AC-3 substreams. Change log level from warning to debug: the E-AC-3 "core" substream can be successfully decoded without the additional and dependent substreams, and their presence is already indicated via avpriv_request_sample in ff_eac3_parse_header.

Ganesh Ajjanagadde	7b11eead1b	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>	9 years ago

Martin Storsjö	8f24c12be7	ac3dec: Don't consume more data than the actual input packet size This was handled properly in the normal return case at the end of the function, but not in this special case. Returning a value larger than the input packet size can cause problems for certain library users. Returning the actual input buffer size unconditionally, since it is not guaranteed that frame_size is set to a sensible value at this point.
