Merge two rtmp live streams into one rtmp live stream with ffmpeg and Nimble

I try to merge one rtmp video live stream with a second audio rtmp live stream. To get translation on a existing live stream

But I get 2 errors:
rtmp server sent error
RTMP_ReadPacket, failed to read RTMP packet header.

I already added the rtmp enable flag to the nimble config file.

My code is:
ffmpeg -loglevel verbose -i rtmp://ip-nimble/rtmp/mainvideo -i rtmp://ip-nimble/rtmp/translation –acodec copy –vcodec copy -f flv -map 0:0 –map 0:1 –map 1:0 "rtmp://ip-nimble/live?rtmpauth=user:password/videowithtranslation“

My final purpose is to have one video live stream with 3 or more extra audio translations.

but first I try to merge for each translation two live streams into one stream.

have you any idea why I get a rtmp sent error?
Most of the people say, it is an autentication problem with the rtmp server.

Hello Joël,

Nimble Streamer supports the in-URL authentication you use, so authentication is not the reason.

I don't understand, how does you FFMPEG command work, because FLV container does not allow multiple audio tracks.

Your task is usually solved by generating different stream for each translation. Just remove "-map 0:1" from your FFMPEG command and it should work.

Please, start new support thread by sending email to help@wmspanel.com so we could deal with specific streams, if you need more info on that.

Hello Andrey
I thought -map 0:0 is video of stream one, and -map 0:1 audio of stream one. and -map 1:0 audio of stream two.

I will setup two live streams for testing.
and send you the specific info by email
