    Default How to change bitrate of audio?

    Hello everyone!
    this is urgent.
    please help me.

    now i am uploading video with rtmp in audio bitrate 44100.
    i used audioonly.xml template in transcoder.
    then when i get stream from wowza to iPhone, i cant play audio.
    maybe i think iPhone app's player doesnt support 44100Hz bitrate.
    so i guess wowza's transcoder can change bitrate, but it doesnt work.
    when i see audioonly.xml, it's bitrate is 48000, but recorded mp4 file's audio bitrate is still 44100.
    that is it doesnt influence change of audio bitrate.
    How can i do it?
    When i play on iPhone video with 8000, 16000, 48000 audio bitrate, it is ok.
    so i am gonna change 44100 into above value.
    i am looking for hearing from you asap.

    Hi there, it sounds like you are playing the source stream as opposed to the transcoded stream.

    To play the transcoded stream you will specify a stream name with _aac appended at the end:
    e.g. mp4:myStream_aac
