Hi!
We are trying to optimize our stream so that it will work on mobile devices. Presently, it works very good on a computer, so the f4m stream is working fine with no issues.

However, when users try to play the m3u8 stream, the video is great, but the audio is terrible! Every second there's gibberish that messes up the audio feed.

Here's the present settings for the stream:
Frame Rate: 25
H.264 Codec - Level 3.0 (for compatibility with early iOs devices) - Keyframe 4 seconds
Video Bitrate: 700 (We tried with 500 and the issue remains)
size: 320 x 240 for both input/output
Audio:
mono
Bitrate: 96
Sample Rate: 44100 Hz
Format: mp3
Can anyone tell us why the audio is so choppy on the ios side and what settings we can change to improve it?

Apple supports following codec for HLS streaming:
Video: H.264
Audio: HE-AAC or AAC-LC
So, change audio codec to HE-AAC and check if it helps.

Chaging from mp3 encoding to AAC in FMLE worked wonders! got rid of the extreme constant choppiness.
How would I have Adobe Media Server to the transcoding for me when making HLS?
