Hi, I posted some questions on this forum but still I’ve not received any clear answer yet. My Question is why the following mpeg-dash adaptive streaming always stops during playing. [http://54.65.203.47:1935/vod/smil:bad.smil/manifest.mpd](http://54.65.203.47:1935/vod/smil:bad.smil/manifest.mpd) The smil file has 2 source videos(high bit-rate and low bit-rate). But each bit-rate source video streamings(mpeg-dash) are all fine. [http://54.65.203.47:1935/vod/smil:bad\_low\_low.smil/manifest.mpd](http://54.65.203.47:1935/vod/smil:bad_low_low.smil/manifest.mpd) [http://54.65.203.47:1935/vod/smil:bad\_high\_high.smil/manifest.mpd](http://54.65.203.47:1935/vod/smil:bad_high_high.smil/manifest.mpd) And even with bad.smil I could play streaming well on the Adobe HDS player. [http://54.65.203.47:1935/vod/smil:bad.smil/manifest.f4m](http://54.65.203.47:1935/vod/smil:bad.smil/manifest.f4m) Is there anybody can give me some clear answer? Following is my yesterday question. > [@\[mpeg-dash\] adaptive streaming error](http://community.wowza.com/t/-/43567): > > Hi, My company is using Wowza streaming engine(version 4.1.1) on AWS. I’ve got some weird problem on the adaptive streaming(mpeg-dash). The streaming url is following.

Seems the error occurs at the loading time of the different bit-rate chunk.

Hi, Regarding that issue it was found to be a problem with the source not being keyframe aligned. If you’re experiencing similar problems then you can troubleshoot this [via the steps outlined here](https://www.wowza.com/docs/how-to-debug-encoder-multi-bitrate-keyframe-alignment). Regards, Paul
