Hi
I am sending 5 streamings via rtmp from a virtual pc, to another machine in the same network, i have setup interfaces as any and to the ip of the virtual machine, everything goes fine, but when i go to the live streams module, outgoing i noticed only 1 streaming is running, the other streams shows as offline, but the feeds are received by nimble streamer, i have other streamings from different urls and works fine, how can i fixed that?

Thanks

Please start new support ticket by sending email to help@wmspanel.com and provide exact stream URLs those you have problems with.

I found the problem.
It is because the audio transcode takes a lot of cpu power, with 1 processor, i am only able to do max 2 hls to rtmp transcodes with -audio aac -ar 44100 -ab 64k -ac 2 -strict -2.
I didn't noticed before, because in that machine i used to do 9 hls restreamings with -video copy -audio copy, i expected to get something similar.
Now i am using the server side task control to do the rtmp transmuxe, but still is using processors at 53%, is there any way to do hls restreaming without transmuxe to rtmp?

Thanks

I forget to mention i am using the server side task control in the host machine with 8 procs not in the virtual anymore.

Please try to use rtsp publish. Rtsp doesn't require 44100 audio so you don't have to transcode audio.

ffmpeg command will look like

ffmpeg -re -i htttp://yourhost.com/live/stream/playlist.m3u8 -c copy -f rtsp -rtsp_transport tcp rtsp://127.0.0.1:7554/live/stream

rtsp -rtsp_transport tcp require to force using TCP. TCP is more reliable to should be considered for such cases.

To use RTSP you:
1) need to setup rtsp inteface as described here

http://blog.wmspanel.com/2015/05/rtsp-transmux-hls-rtmp-dash-mpeg2ts.html

2) please do that carefully. and don't switch current production streams. create new stream for tests first

3) recommended ffmpeg versions are 2.8.x. Rtsp works strange with 2.5.* sometimes
