A_eac3 Codec Download
Claretha Beuter
I've just tried to play a video file in Kodi with the audio codec: A_EAC3 and the audio is just scratching and beeping. Does Kodi support this codec at all? In case it doesn't, is there an easy why to resolve the problem?
Have you tried running Gspot, it's a good program which identifies exactly which codecs you need to play a video and says if the codec is installed or not whether it's a video or sound codec.

But i'm not completely sure if it works on HD videos or not, can always give it a try.
One way I obtained the delayed result is this command to re-encode: ffmpeg -i %sourcemkv% -vcodec libx264 -profile:v high -crf 23 -tune film -level 4.1 -acodec aac -b:a 160k -ac 2 re-encoded-with-aac.mkv
The point is, that many audio codecs, can not start at PTS zero - and AAC is one of them. There is a "settling phase" at the beginning (I don't know the exact english word, in my native German it is "Einschwingphase"), where the audio output can not yet carry payload (silence is presented instead).
Things start to become even messier, when you encode from one codec with a settling phase of X ms into another codec with a settling phase of Y ms - in this case, there might even be a positive delay, when the old codec needed longer to sttle than the new codec does.
Based on Eugen's answer, I searched and found out more information on this VideoHelp Forum thread about codec dependant silence i.e. delay generated at the beggining of encodings.I then stumbled upon Apple's QAAC encoder and one of its options which allows trimming of the encoder specific delay, also suggested on a VideoHelp thread on delays:
ffmpeg -i /videoRecords/France-2-HD-Match-Point.2011-02-20.20-35.mkv -map 0.1 -acodec copy /videoRecords/MatchPoint1.eac3
it start normally without issuing any error and then suddently I get a bunch of
