Hi all, I have a problem when using origin/edge: I published some streams by StartupStreams.xml on origin server: ```auto liveorigin/_definst_ rtp VTC2/VTC2_320x180_400kbps.stream liveorigin/_definst_ rtp VTC2/VTC2_416x240_500kbps.stream liveorigin/_definst_ rtp VTC2/VTC2_480x270_800kbps.stream liveorigin/_definst_ rtp VTC2/VTC2_640x360_900kbps.stream liveorigin/_definst_ rtp VTC2/VTC2_640x480_1200kbps.stream ``` I put these streams on content/VTC2 folder. I created VTC2.smil on that folder: ```auto

``` When I used live Smooth streaming: “[http://192.168.1.114:1935/liveorigin/](http://192.168.1.114:1935/liveorigin/)_definst_/smil:VTC2/VTC2.smil/Manifest” ,after some seconds it had error: “Media error: 3001 AG\_E\_INVALID\_FILE\_FORMAT”. When I used “[http://192.168.1.114:1935/liveorigin/](http://192.168.1.114:1935/liveorigin/)_definst_/VTC2/VTC2\_320x180\_400kbps.stream/Manifest”, after some minutes, it had error: “Media error: 3050 Reached the end of known chunk list…” or “Media error: 3050 timed out 10 consecutive times for stream” Please help me! ---

Can you play each stream individually in Smooth player? What about Flash RTMP player? Do you have “smoothstreamingpacketizer” in the Application.xml /LiveStreamPacketizers ? Richard ---

Duc, Each stream must be key frame aligned with each other for switching to work. You can test by enabling this debug Property [https://www.wowza.com/docs/how-to-debug-encoder-multi-bitrate-keyframe-alignment](https://www.wowza.com/docs/how-to-debug-encoder-multi-bitrate-keyframe-alignment) Richard ---

Hi Richard, I can play all stream individually in Smooth player, Flash RTMP. Sometime, I can play s.mil file, individual stream few hours ok. I have “smoothstreamingpacketizer” in the Application.xml /LiveStreamPacketizers. I dont understand “encoding details” and “audio and video track”. My encoder uses Baseline profile. Thanks, Duc
