We are testing Wowza Streaming Server to see if it suffices our VOD streaming need. So far MP4 videos look ok, but some of the .MOV video files which have **in24** (Little Endian PCM) audio can only play video without audio. We are wondering if Wowza can support in24 audio, or if there is any way to make it support in24 audio?
Thanks.

Hi dragonwave, I’m not sure about in24 support, it’s like Sony camera codec. Even if wowza support in24 audio , you’ll come across problem in playback android , ios etc.
The best way for vod streaming , h264 video codec , aac audio codec with 44100, cause mp3 not supported by android. If you think that wowza will transcode it while playing , Check that wowza transcoder not used for vod streaming .

Hello there,
Wowza Supports mp3 and AAC incoming audio, and the Wowza Transcoder supports the following codecs for decode:
**AAC**
**G.711 (µ-law and A-law)**
**MPEG-1 Layer 1/2**
**MPEG-1 Layer 3 (MP3)**
**Speex**
Thank you.
Salvadore

Hi dragonwave, I don’t have an any video with this codec but I wanna learn that , what is mean playback on the desktop ? with flash player ? or via vlc etc ?
Secondly , you say that only video play , which player do you test it ?
Can you test it with ffplay -i “http://…/playlist.m3u8” ?

how many videos do you have ? You may try to convert audio codec to aac with ffmpeg on strong server , bcause converting kill the cpu and ram 🙂

Thanks Emre for replying. We are not going to playback on android or ios. We are just going to playback the streaming video on desktop. The task is very simple and straightforward — streaming video files so users can playback on the desktop.

You are right, Emre. We are trying to playback in a flash player embedded in HTML. I have used Wowza player and JW Player. None plays sound, only video plays.

Thanks Salvadore. Wowza Streaming Server suffices everything we need, except this one. How regretful that we probably can’t use it. ☹
