Live encoding H264 to FMS via ffmpeg command-line or Java code

Report · Feb 03, 2010

Hi folks,

We just shipped Xuggler 3.4 this weekend which now has the ability to record and publish RTMP streams. That means you can now write Xuggler (a Java API for encoding and decoding video) programs that can publish to FMS or record from FMS.

We've worked closely with the FFmpeg team to get the core RTMP stack into that project, and have put together a tutorial on how to use FFmpeg to record or publish streams, including re-encoding media to H264/AAC while publishing. You can find that tutorial here.

I thought people here would like to know.

I couldn't even get the program to install correctly on windows Vista .................I didn't try to install as administrator......is that a requirement?

Yes, it needs administrator privledges to set the PATH variable in Windows to point to the location of the necessary DLLs.

Is home4.flv a valid media file? Can you post it somewhere so I can take a

look at it?

Hi Calmchessplayer,

This looks like a bug in that demo which we'll try to fix in a future release, but to see an example of the API working, you can use the Converter program to convert that file to a Quicktime file:

java -cp /home/aclarke/Stage/share/java/jars/xuggle-xuggler.jar com.xuggle.xuggler.Converter hom4.flv out.mov

I tested with your file and that works.

Hi, Art,

I want to stream encode a file live into H264 and stream it to a FMS server using your native RTMP functionality. I followed your livestream tutotrial:

http://wiki.xuggle.com/Live_Encoding_Tutorial

I run the following command

ffmpeg -i /testFiles/testScooter.flv -acodec copy -vcodec libx264 -fpre /usr/local/xuggler/share/ffmpeg/libx264-default.ffpreset -re -f flv rtmp://encoding02.testserver.tv/stream/1479_a92bf8927f8914ac23d66485abcfdce5

Then I get this error:

Could not open 'rtmp://encoding02.testserver.tv/stream/1479_a92bf8927f8914ac23d66485abcfdce5'

I think this is the reason:

Xuggler interprets stream as the app and 1479_a92bf8927f8914ac23d66485abcfdce5 as the stream name. However my FMS server encoding02.testserver.tv has app name stream/1479_a92bf8927f8914ac23d66485abcfdce5.

It works with wowza. And there is no restrictions from the server.

So what would be a possible soution to that?

Thank you for your time,

regards Georgi
