Choppy/Stuttering Audio

Wowza Streaming Engine
1

Hi,

I have an RTP stream fed into Wowza. I am using stream files tab to pick this MpegTS IP stream.

When I try to transcode this to H.264/AAC, I see timecode out of order issues in error log.

But when I enable mpegTSAudioAligned feature under Stream File --> Properties --> MpegTS and set it to True, the timecode out of order error disappears but when I playback this transcoded H.264/AAC stream, the audio is terribly choppy.

Any ideas how to sort this?

Thank you

Hello,

I would recommend you look in to changing the RTP Jitter Buffer properties that are outlined here.

In addition to enabling mpegTSAudioAligned you can also increase the buffer time in rtpDePacketizerPacketSorterBufferTime.

Further details about setting the packet sorter buffer time can be found here.

Hope this helps.

Regards,

Alex
