HTML5 / HLS / mp4a.40.34 problem

Wowza Streaming Engine

Hi,

we’ve an issue trying to add HLS support on HTML5 desktop browser. We’ve mp3 audio-only files, and we’re trying to stream with Wowza 4.5 using jwplayer/hlsjs but mp3 stream doesn’t work.

It’ seems there’s an issue with hls manifest that set audio codec to “mp4a.40.34” which is not supported by Chrome and Firefox.

For example this manifest doesn’t work: http://video.radioradicale.it/store-66/definst/mp3:2016/11/MP862180.mp3/playlist.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=63701,CODECS="mp4a.40.34"

instead this other stream works using hlsjs dev: https://player.webvideocore.net/playlist.m3u8

#EXT-X-STREAM-INF:BANDWIDTH=63701

Demo: https://nochev.github.io/hls.js/demo/?src=https%3A%2F%2Fplayer.webvideocore.net%2Fplaylist.m3u8&enableStreaming=true&autoRecoverError=true&enableWorker=true&levelCapping=-1&defaultAudioCodec=undefined

This is the discussion: https://github.com/dailymotion/hls.js/pull/808#issuecomment-261555621

how can we remove

CODECS="mp4a.40.34"

from mp3 hls manifest?

thanks

Hello!

Thanks for contacting Wowza Forums!

Can you take a look at this article? It shows how to add this property to your output playlist. See if you have this enabled and if so, disable it by changing the value to false
