I'm creating a MPEG-TS files which has an encoded AAC audio track 
(aacenc.c) but when the AAC packets are added to output container I get 
the error:
>> AAC bitstream not in ADTS format and extradata missing
> I've found adtsenc.c in the source (which is a muxer) but I don't knw

It seems that I've fill to fill extradata with some info to get MPEG-TS 
muxer to internally create an ADTS muxer.
Now I'm getting the error:
> MPEG-4 AOT 0 is not allowed in ADTS
How do I have to initialize extradata in order to have adtsenc.c to be 
correctly configured?
