ffmpeg rtmp sender
simonb
ffmpeg I use this command...
ffmpeg -i "some_video.vob" -re -vcodec libx264 -vpre default -vpre
baseline -b 500000 -s 320x180 -strict experimental -g 25 -me_method
zero -acodec aac -ab 96000 -ar 48000 -ac 2 -b 500K -f flv
rtmp://127.0.0.1/live/test
rtmpd reports...
Stream 1 of type NR with name `` unregistered from application
`flvplayback`
Stream 2 of type INR with name `test` registered to application
`flvplayback`
short name: test; long name: test
I then try and play the stream using this command...
vlc rtmp://127.0.0.1/live/test
But it can't find the stream.
I have the same story using flv and mpegts uplinks. ffmpeg seems to
connect OK but I can never find the URL to point VLC to to see it.
The live ffmpeg example in the wiki seems to use UDP. Now ffmpeg
supports rtmp streaming would it be possible to have an rtmp example
in the wiki? Also most of the examples I could find so far in the
mailing list and wiki only show how to uplink to the server. Matching
client side examples would be useful to show what to point the client
(viewer) at.
Thanks & regards,

Of course is not working. You try to transfer flv over RTMP. You either pick up "-f flv tcp://localhost:6665"
or
-b 500K rtmp://127.0.0.1/live/test
you can't mix -f flv with rtmp://

P.S.
Didn't tested it yet, but I'm pretty sure about it

Try adding -metadata streamName="test" to your ffmpeg command line.

I tried ffmpeg without the "-f flv" and it barfs with,
"Unable to find a suitable output format for 'rtmp://localhost/live/
test'"
I tried "-f raw" and get,
"Requested output format 'raw' is not a suitable output format"
All the documentation for using ffmpeg to send to FMS, Wowza or Red5
seems to require the flv format.
http://www.ffmpeg.org/ffmpeg-doc.html#SEC43
http://wiki.xuggle.com/Live_Encoding_Tutorial
I did have more luck with tcp://localhost:6665 though. If I catch the
127.0.0.1_xxx.flv name from the rtmpd output then I can pick it up
with
ffplay rtmp://localhost/live/127.0.0.1_xxx.flv.
For some reason ffplay works and VLC doesn't, though VLC has worked
with Wowza and erlyvideo.
I tried changing the name using "-metadata streamName="test but it
seems to be ignored. I can still only connect to the 127.0.0.1_xxx.flv
name. The output I get from ffmpeg looks like it has added the
metadata...
"Output #0, flv, to 'tcp://localhost:6665':
Metadata:
streamName : test
encoder : Lavf52.64.2"

To send I use...
ffmpeg -i myvideo.mp4 -re -vcodec copy -acodec copy -f flv
rtmp://localhost/live/livestream
To receive I use...
rtmpdump -r rtmp://localhost/live/livestream -q -o - -v | ffplay -
or...
rtmpdump -r rtmp://localhost/live/livestream -q -o - -v | vlc
stream:///dev/stdin
In theory using ffplay or vlc directly should work but it doesn't.
It does, however, work with Flowplayer which is the most important
result for me :-)
jimi
in the Article on Wiki. However i am Unable to View the Stream on
jwplayer or haxe
With the Steps Mentioned Below did it work with FlowPlayer??
Could you please shed some insight on playing with FlowPlayer??
jimi
The Options(ffmpeg line) you mentioned below Do not Work For Me.
Anything else you configured??

What happens? Does ffmpeg not start? What error messages, if any, do
you get?
I am not using any transcoding in the example I gave. It assumes the
input file is already transcoded as required. Perhaps you need a more
elaborate ffmpeg command to encode the video first (just a guess) such
as the the one in my first email...
ffmpeg -i "some_video.vob" --re -vcodec libx264 -vpre default -b

Simon
jimi
Thanks For the Prompt Reply...
I am Also Not Using Transoding. I am Issuing the Following Command
from Command Line
# ffmpeg -i hiss.flv -re -vcodec copy -acodec copy -f flv
rtmp://localhost/live/livestream
The Output is as Follows:

Should The Input File be an .mp4?? i Shall Try with AVI file and Use
transcoding approach. I shall get back to you with the Results.

FLV, AVI, MP4 etc are just container formats. As long as they contain
H264/VP6 and AAC/MP3 the result should be the same. I don't think the
framerate warning is responsible for the "TCP connection to localhost:
1935 failed: Connection refused" message.
It seems you are not connecting to the rtmpd server. Is it running? Is
there a firewall that is blocking even localhost-localhost
connections. Try installing nmap and typing "nmap -p 1935 localhost"
to see if the port is open.
Also check the debug output from rtmpd. That might give more clues.
With the default config there should be plenty of print-out whenever
anything connects to it.

Yes the rtmpd server is Running. I shall Check whether the Firewall is Blocking localhost-localhost
I Did check the rtmpd server console. Nothing Unusual it seemed. I shall Have a Dekko once again.

The rtmpd server was running. I shall check the Firewall blocking
scenario as u suggested as well as the console of the rtmpd server.
Last time checked the server did not throw anything unusual.
What is the OS that you are using??

I'm using Ubuntu 10.10 desktop.
The rtmpd console should show at least some new output when you try to
connect.

I too am using Ubuntu 10.10. Just now Upgraded to 11.04 Alpha. Nothing seemed Unusual in the rtmpd console.
Shall have a relook at the Output again.
Thanks and Regards,

Please explain "nothing unusual". Are you getting any output on the
console when you try and connect or does it not change?
Thanks,
Simon
shashi kiran
Sorry for the Delayed Response. Had some issues with my Laptop. Got it fixed. The Console Prints messages which seem fine. I shall Paste the output here.
