A little stuck streaming Flash on Debian

[stephan]

Hi,

I used to use ffserver, but I've had real stability issues with it recently and would like to switch to vlc.

I have a webcam which streams in mjpeg format and a dedicated server that I'd like to use to encode to .flv and then display on a website.

From reading the documentation, I think the command should be this:

vlc -v http://username:password@my-home-camera ... video.mjpg --sout "#transcode{vcodec=FLV1,acodec=mp3}:std{access=http,dst=server-ip-address:80/stream.flv}"

I think that's right, although in my case I don't have sound so could probably take out ",acodec=mp3". I've left it in for the moment while I work this out.


Anyway, that's the background information...

I'm running Debian Lenny (the testing version). I think the reason my streaming isn't working, is that perhaps my version of VLC isn't high enough. Possibly.

I have put in the apt sources from this page: http://www.videolan.org/vlc/download-debian.html

and now I'm on version 0.8.6h I think.

It's not quite working unfortunately, this is what I get when I run the command above.

VLC media player 0.8.6h Janus

[00000291] main input error: cannot start stream output instance, aborting


So, I'm wondering if anyone can let me know what I'm doing wrong. Also, what's the minimum version number I should be running?
Your help is appreciated, I'm going mad here!

Thanks.

I'm nearly there now. I think the command is right:

vlc -vvv http://username:password@camera-stream- ... video.mjpg --sout '#transcode{vcodec="FLV1"}:standard{access=http,mux=ffmpeg{mux=flv},dst="server-ip-address:80/stream.flv"}'


I can't view the stream in any players I've tried though.

It is http://server.fishycam.com/fishycam.flv , if anyone is up for checking it for me? That would be useful.

[stephan]

Ok, so now I guess that the reason it doesn't work is perhaps that it can't tell where each frame of my input video starts and finishes?

I can only guess that the video it is outputting is corrupt, as I can't get it to play in anything.

The camera I'm using streams in Mpjpeg format, basically lots of jpg files stuck together.

I *really* need help with this, I'm at a total loss...

[stephan]

Now I don't think it's corrupt due to the encoding of the video, but am still stuck.

Has anyone done this before?

[stephan]

I've added in a bit for the mime type. It still isn't giving back the right output though.

Code: Select all

vlc -vvv http://username:password@my-webcam/mjpg/video.mjpg --sout '#transcode{vcodec=FLV1}:standard{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=my-ip-address:80/streamname.flv}'

When I access the stream using curl -I , the headers seem right:

HTTP/1.0 200 OK
Content-Length: 0
Content-type: video/x-flv
Cache-Control: no-cache


Is anyone able to help please? I've read the documentation, I just can't tell what I've done wrong here. I've tried two different version of VLC.

Can someone post your working details please?

There is my example:

vlc -I dummy -vvv http://**.**.**.**:8891/video --sout '#transcode{vcodec=FLV1,vb=320}:standard{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=0.0.0.0:8091}' --color --loop --no-audio

Hi,

Thanks for posting that, I've been going a bit mad here!

It doesn't work for me, but your version of VLC is much higher, so I've got something to do there... Thanks again, much appreciated.

Hi !

Here is a line which works for me :

vlc mysource.avi --sout
'#transcode{vcodec=FLV1,scale=0.5,acodec=mp3,samplerate=22050}:std{access=http,dst=192.168.0.7:1234/stream.flv}'
-I http --http-host 192.168.0.7:8080

( Be sure to specify the audio samplerate to 44100, 22050 or 11025 ) .

People say that vlc version 0.9 is minimal requirement for flash streaming.

[stephan]

Thanks I've got it working now.

I got the latest VLC off the Debian experimental repository. Probably not a great idea, but hey...

and it's not running as root!
