HLS-LIVE streaming problems

Good day,

we are using Adobe Flash Interactive Media server 4.5.1, trying to stream to iPhone/iPad

1) Encoding parameters are as follows(see attached screenshot)

2) When opening a stream on Ipad/iPhone the audio is corrupt. You can see this when opening the following link http://broadcast06.quantumart.ru/hls-live/adaptive-dfm/_definst_/dfm/livestream.m3u8

P.S. In of the recomendations - there was a recomendation to use AAC instead of MP3. For AAC encoding in FMLE we have bought AAC encoder - when encoding to AAC there is no audio AT ALL!

    Using the specified aabove AAC encoder, i get constant errors in FMLE, and the broadcasting stops. Here are the logs:

    While using MP3 everything works great except for "hickups" in audio on iPhone/iPad

    There are lots of encoders but some of them might be quite pricy. You can try ffmpeg.

    But i think before you move - i think you should either raise this issue on FMLE forums or write to Mainconcept (you paid for it)

    Yes you need to use AAC for HLS to work. When using AAC if you are not getting any audio i would suspect there is some issue either in input device or your AAC plug-in

    We are using MainConcept AAC Flash Media Life Encoder - i admit, that it may-be buggy. Which aac encoder for windows systems would you reccomend?
