VOD audio bitrate

how can i adjust bitrate of a mp3 track to 32k,64k ?

i have uploaded 1 mp3 file to /usr/local/Wowza/content/sample.mp3

i have checked with VLC player rtsp://ip:1935/vod/mp3:sample.mp3

its not streaming smoothly also i checked with testplayers it shows bitrate 250+k may be that is the reason why its not playing smoothly?

Hi,

You can’t adjust the bitrate with any server-side settings.

You could certainly try re-encoding it with ffmpeg like this to see if playback improves:

ffmpeg -i sample.mp3 -ab 64k sample_64k.mp3

Hi,

You would use a .smil file to support different viewers/listeners bandwidth conditions,

This is also know as multiple bitrate or Adaptive Bitrate (ABR) support.

You would specify different file renditions in the .sml file to support different bitrates.

A file has to exist for each of the required bitrates.

This is explained in more detail in this article.
