FFMPEG : Transcoding

Hi,

I'm trying transcoding a live streaming with this code :

/usr/local/bin/ffmpeg -i rtmp://163.172.25.219:1935/test/test -vcodec libx264 -preset veryfast -b:v 2000k -maxrate 2000k -bufsize 2000k -s 1280x720 -sws_flags lanczos -r 60 -acodec copy -f flv rtmp://163.172.25.219:1935/test/test2

But it does not work.

regards,

Hi,

Please specify what exactly doesn't work - what behavior do you see.
If it's related to Nimble Streamer, please post your question to https://wmspanel.com/help

Hi,
you need rtmp authentication like:

-f flv "rtmp://ip-nimble-server:1935/application?rtmpauth=user:password/stream"

Nimble rtmp authentication

rtmp://user:paaswd@server:1935/live/test

Ubuntu 14.04 should be amended as follows

/usr/local/bin/ffmpeg -i
to
ffmpeg -i

rtmp
I created interface and application with the name "live" login and password also "live"
in ffmpeg rtmp://live:live@ip/live
I get [rtmp @ 0x561816633140] Can not read RTMP handshake response
If I try to use srt then
[srt @ 0x55c5c96b0540] Connection setup failure: connection time out.
srt: //80.85.245.11: 1234: Unknown error occurred
11: 58: 41.143066 / SRT: RcvQ: worker !! FATAL !!: SRT.c: CChannel reported ERROR DURING TRANSMISSION - IPE. INTERRUPTING worker anyway.

Hello Andrey,

Are you trying to pull or push RTMP stream? What is the full command you're trying to use?

coder push to nimble
if push mpegts udp there are problems with delays. Coder and Nimble are located in different cities

coder ubuntu
ffmpeg -y -re -i $FILE_INPUT -map 0:v -c:v:0 $VCODEC -vf:v:0 bwdif=0 -r:v:0 25 -maxrate:v:0 300k -bufsize: v:0 300k -b:v:0 300k -s:v:0 640x480 -profile:v:0 main -map 0:v -c:v:1 $VCODEC -vf:v:1 bwdif=0 -r:v:1 25 -maxrate:v:1 600k -bufsize: v:1 600k -b:v:1 600k -s:v:1 1024x768 -profile:v:1 main -map 0:a -c:a:0 $ACODEC -b:a:0 64k -f flv "rtmp://live:live@nimble_ip/live"

In nimble created interface and application with rtmp and name "live" login and password also "live"

Try to push it without authentication enabled, will it work?

I'd also suggest to try pushing with URL authentication like it described in https://blog.wmspanel.com/2014/07/rtmp-publish-url-authentication.html article.

in coder
[rtmp @ 0x55745b76bac0] Cannot read RTMP handshake response
rtmp://nimble_ip/live?rtmpauth=live:live/stream: Connection reset by peer

without authentication
Global setting Nimble clear login and password and clear login and password in application "live"

[rtmp @ 0x56021f8c00c0] Cannot read RTMP handshake response
rtmp://nimble_ip/live: Connection reset by peer

Please check nimble.log on the server, are there any errors?

No(
