I want to distribute a RTSP livestream from a local encoder (1,5 MBit bandwidth per stream) via RTMP.

In general the stuff is running, but every 60-90 secs (even in the local LAN) I am experiencing a kind

of “hiccups” where the video/audio stops for some milliseconds and then continues. I tried different

RTMP plugin (JW, Videojs, Flow), but had no success. I also modified buffers on the Wowza side without

any improvement.

VOD files via RTMP are being streamed w/o any issues.

Any ideas?

Any recommendations?

Hello, can you please provide your encoder settings? i.e

fps

GOP (key frame interval)

audio/video codec

Regards,

Current Profile Settings:

D1 resolution,

H.264, 25fps, 1500kps

AAC 32kHz Stereo 96kps

cannot set the GOP value on the encoder

([http://www.umediaserver.net/hardware/UM400.pdf](http://www.umediaserver.net/hardware/UM400.pdf))

Any idea with that settings?

If I connect via VLC directly onto the encoder I do not experience any issues & hiccups.

So I assume something on the Wowza/RTMP side.
