RTMPDump query to ffmpeg query? (nginx rtmp module)

[sinanksu]

Hi,

I want to reflect a live broadcast from rtmp in the same way as "nginx rtmp module".

I ran that live broadcast with the following rtmpdump query. I installed an Ubuntu server. Then I installed the nginx rtmp module. This module has ffmpeg in the examples.

How do I write the rtmpdump question on fmmeg?

Successful rtmpdump query:

rtmpdump -r "rtmpe://xx.xx.xx.xx/xlive" -a "xlive" -f "WIN 23,0,0,162" -s "http://xxxx.com/Player.swf" -w "5aaaa32059cba7xxxxxxxxxxx" -x "585534" -p "http://xxxxxxxxxxxx.com/viewer?game=1" -C S:client -C S:3.1.0.10 -C S:en --live -y "raw:472237" -o "2017blablabla.flv"

rtmp {
server {
listen 1935;
chunk_size 4096;

application live {
live on;
record off;
exec ffmpeg -i "rtmpe://xx.xx.xx.xx/xlive" -a "xlive" -f "WIN 23,0,0,162" -s "http://xxxx.com/Player.swf" -w "5aaaa32059cba7xxxxxxxxxxx" -x "585534" -p "http://xxxxxxxxxxxx.com/viewer?game=1" -C S:client -C S:3.1.0.10 -C S:en --live -y "raw:472237";
}
application live360p {
live on;
record off;
}
}
}

Thank you

Use librtmp parameters with ffmpeg.

Hi j_cool,

I tried but I could not get it working.

Hi j_cool,

Thank you for your reply.

I tried it like this. But I have not been successful. It works with RTMPDump but it does not work with ffmpeg. Also I could not send you the swf in ffmpeg. This swf size parameter does not exist.

[j_cool]

This is not right:

flashVer=WIN%%24,0,0,221

It is about handling empty space within parameter.
From beginning to the end of parameter no empty space is allowed.
It is replaced with %%20 in batch file, with %20 on command line.

You can see real life example in my old post,

http://stream-recorder.com/forum/sho...57&postcount=3

and here it says it right.

Your progress is good, it is troubleshooting little bits from here now on.

One more to "escape":

? with \?

But I did not. Unable to verify SWF.

When I used rtmpdump in the past, I could not verify the swf. Then I added the swf size to the query. And rtmpdump worked.

Now, there is no parameter needed to add swf size to ffmpeg.

How will I do.

Your question is complicated, but the answer can be simple.

If something worked well with rtmpdump, it must work with ffmpeg as well. FFmpeg and Rtmpdump are both based on librtmp.

It is just matter of "translating" rtmpdump command to ffmpeg command.

There is one simple example of that, here.

http://stream-recorder.com/forum/ple...ng-t22585.html

escaping ? with \? appears not to be necessary in this case, so this is error here,
( Required only inside the regex pattern of FINDSTR ).
I noticed it is an error when I saw it showing on command line when you executed the command, on command line
you should see it all "as is", and purpose of escaping in batch file is to see it "as is" on command line.

Appart from that, I cannot see other syntax error in your last ffmpeg command so I suspect parameters themselves.
To solve that I would try to replicate parameters identically from old rtmpdump command that worked.
