tech question

We have a CDN with live transcoding and are updating it to our own based on AWS instances. I have pretty good experiences with EMS but can’t solve one problem. What we need to do is to have one input, that is being transcoded to 5-6 qualities depending on the input. Then, we need to generate a HLS playlist. And here come the 2 problems. 1. when I setup the transcoding to load the stream via RTSP, it breaks down the picture – http://tinypic.com/r/f26142/9 2. When I use rtmp link for the transcoder, the HLS generated are not in sync and there is a visible delay on switching the sources. I have it running on a AWS c3.4xlarge instance, that should be powerfull enough to handle this. The commands I use: transcode source=rtmp://localhost/live/input groupName=trans videoSizes=480×270,640×360,960×540,1280×720,1920×1080 videoBitrates=800k,1200k,2200k,3500k,6000k audioBitrates=96k,96k,96k,128k,128k targetStreamNames=trans-270,trans-360,trans-540,trans-720,trans-1080 destinations=trans-270,trans-360,trans-540,trans-720,trans-1080 videoAdvancedParamsProfiles=streamstar-60,streamstar-60,streamstar-60,streamstar-60,streamstar-60 transcoding setup, custom avconv preset: g=60 preset=superfast profile=main level=31 HLS creation: createHLSStream localstreamnames=trans-270,trans-360,trans-540,trans-720,trans-1080 bandwidths=800000,1200000,2200000,3500000,6000000 targetfolder=/var/evo-webroot/hls/ groupname=trans playlisttype=appending chunkLength=10 hlsResume=1 chunkOnIDR=1 I need to solve this really quickly or I will have to find for another solution. And we are talking about a big usage and a CDN serving several instances at one time.
