Stream to Shoutcast + Flash Player + Video + VLC = Working!

[kdh]

OK, I will test this tonight.

I noticed I've had to really bump up my --sout-mux-caching levels on the server side. If I do a vlc -vvv with my command, the output tells me something about waiting for SPS or something and takes a really long time for it to sync up, but it does.

I'm not sure if that makes sense. But I'll post the output to what I'm talking about later.

thanks for the help!

Here is the messages I'm talking about:

[00000506] packetizer_h264 packetizer warning: waiting for SPS/PPS
[00000506] packetizer_h264 packetizer warning: waiting for SPS/PPS
[00000506] packetizer_h264 packetizer warning: waiting for SPS/PPS

I get a bunch of these, and then wham. it works.

[00000506] packetizer_h264 packetizer debug: found NAL_SPS (sps_id=0)
[00000506] packetizer_h264 packetizer debug: found NAL_PPS (pps_id=0 sps_id=0)
[00000430] main stream output debug: adding a new sout input (sout_input:0xb7514028)
[00000431] stream_out_transcode stream out debug: creating video transcoding from fcc=`h264' to fcc=`FLV1'

But it only works if I have that caching way high. What do you suggest, or is that not really a bad thing?

[kdh]

That should go on the client side right?

Where would the venc=x264{keyinit=30} in my string? Something like this?

:sout=#transcode{vcodec=h264,vb=100,fps=30,scale=0.5,acodec=mp3,ab=96,channels=2,samplerate=44100,venc=x264{keyint=30}}:std{access=udp,mux=ts,dst=mywebsite.com:8777}

yes, like that. Also I think it's better to use width/height instead of scale (but thats pretty small issue).

is the keyinit=30 directly tied to the fps=30 setting? or can they be different?

[ILEoo]

Keyint tell how many frames there are between keyframes, and on stremaing, it should be 1-2s to get reasonable fast start on viewing.

AH! So thats why I have to have my caching so high. K.. I don't know why it didn't click before, but when you said it.. I was like duh.

Most testing when I get home from work!

I'm also NOT going to use the .05 scale option anymore and move onto the size instead.

Thanks!

[kdh]

server side i'm getting this message:

[00000587] mux_ts mux warning: packet with too strange dts (dts=3025523014894,old=3025523050972,pcr=3025523050972)

What can I do to resolve it?

anyone got any hints?

live streaming from a club.. wouldnt happen if we didn't have vlc!!

Hi!, Im going to install a server for test vlc and transmit shoutcast to flash player, i'm going to folow your instructions.

I have a question, is it possible to create a second setram, but deferred (1,2 or 3 hrs back in time) from the original stream?

maybe saving a file, and stream it 1,2 or 3 hrs after the main stream has started?, does this file can be limited to be of some max size?

or maybe save many small files of x amount of minutes, and then stream them in order?

thankyou for your support, i'll be working on this proyect and i´ll share the results as i get them.

[kdh]

I would guess you'd have to save a file and then start a 2nd vlc server to read that file 1 or 2 hours after you started recording to it.

its something you'll have to mess with and test. You'd have to script it all. I do everything on linux so most of my scripting is done in bash or perl depending on what i'm doing.

max size of file is really dependent on the OS. Like ulimit sizes are around 2gigs, but you can over ride them.

what os are you running?

[selten]

I´m going to install a new one, so I can choose from all of them W32 or Linux wich I like the most.

I been thinking about this idea, and I think I have some solution for it, I need only to mount the server and start streamming to it, and saving to files.

I'm not an expert about Linux programing, if I need some help I´'ll be back asking for it, or some clue to solve it.

right now i'll install the OS, and the last VLC version, what do U suggest to install extra? shoutcast server, flash setram server, wowzamedia?

[kdh]

im only using vlc and shoutcast server.

i do all my server side stuff on linux.. client is windows. I can give you some basic hints when it comes to perl or shell scripting, but i don't have any full on code to share.

best of luck.

[selten]

Thankyou very much for your support, i'll post any advance i got to share it, maybe I can give back something withg this proyect.

[kdh]

be sure to create your own thread as lots of people would love to see how its done. =)

Hello kdh,
Thanks for sharing. I have a few questions:

In this command, I connect back to 127.0.0.1:9070 and turn it into something that a Flash Based Video player can understand and stream to my website.

vlc --freetype-font=/usr/share/vlc/skins2/fonts/FreeSans.ttf --sub-filter=marq --marq-size=20 --marq-position=9 --marq-marquee="Live: $showname" http://localhost:9070 --sout-mux-caching 45000 --sout-ffmpeg-qmin=10 --sout-ffmpeg-rc-buffer-size=20000 --sout-ffmpeg-qmax=30 --sout-ffmpeg-qscale=1 --sout-ffmpeg-luma-elim-threshold=-4 --sout-ffmpeg-chroma-elim-threshold=7 --sout "#transcode{vcodec=FLV1,acodec=mp3,vb=100,ab=64,sfilter=marq}:std{access=http,mux=ffmpeg{mux=flv},dst=everydayjunglist.org:8081/stream.flv}" --daemon

What is the outcome of this command? A flv file get generated?

Similarly,

n this command, I connect back to 127.0.0.1:9070 and turn it into something that a Flash Based Video player can understand and save the in coming audio and video to file.

vlc --freetype-font=/usr/share/vlc/skins2/fonts/FreeSans.ttf --sub-filter=marq --marq-size=20 --marq-position=9 --marq-marquee="Prerecorded: $showname" http://localhost:9070 --sout-mux-caching 45000 --sout-ffmpeg-qmin=10 --sout-ffmpeg-rc-buffer-size=20000 --sout-ffmpeg-qmax=30 --sout-ffmpeg-qscale=1 --sout-ffmpeg-luma-elim-threshold=-4 --sout-ffmpeg-chroma-elim-threshold=7 --sout "#transcode{vcodec=FLV1,acodec=mp3,vb=160,ab=96,sfilter=marq}:std{access=file,mux=ffmpeg{mux=flv},dst=./myrecording.flv --daemon

Does it generate a file "/myrecording.flv"?
How do I receive it by using flash form the client browser? Just point to the flv file generated here?

All your commands are about vlc, is there anything need to done for the ShoutCast server?

Looks promising and I am getting ready to try out!

Thanks a lot!
Kevin

[kdh]

kevin, that first command takes my stream and turns it into something an web based flash player can understand in real time. No flv file is created. It creates an http link to this: everydayjunglist.org:8081/stream.flv and then I have a webpage that points to it. I used to use the longtail video player but recently switched to flowplayer. You can see the source code by looking at the source code of this page for details http://www.everydayjunglist.org/edjtv.v2.html

That second command yes, does create a file for archival reasons. If you like.. check this out.. it was recorded tonight for a halloween special. http://radio.everydayjunglist.org/recor ... 1.2009.flv

hope that helps.

As for shoutcast. Your shoutcast server needs to be set up correctly. Meaning, a normal shoutcast install will work. No really mucking with shoutcast needs to be done. If you understand shoutcast, my commands on the first page of this thread will intergrate with shoutcast.

[kevin8161]

Great. Will give it a try. Thank you kdh!

Just heard that http streaming will be supported in the new flash player 10.1. Would that simplify everything? no more need for ShoutCast in the middle?

http://blogs.adobe.com/ktowes/2009/10/r ... ulti-.html

[kdh]

the main reason why we use shoutcast is its a very popular format. so if you goto shoutcast.com and type drum and bass, or jungle, our radio stream will pop up. this enables random listeners to easily find us.

the problem with flash 10.1 is (i think) they charge a license fee tp use it... that and it only does flash.

with some tweaking, i can make vlc do all sorts of awesome stuff for me and i can do it for free.

is this also working with IceCast (Server) and NSV (for streaming the WebCam)?

[kdh]

There are some threads to make it work with IceCast but I haven't had any reason to try. Same with NSV.. but NSV is pretty much unsupported and slowly dieing. Our site would have run NSV, but Flash seemed the better route.

[kdh]

My How-To has NOT been tested with Shoutcast 2.0. Only Shoutcast 1.X.

Also..

If VLC drops support for Shoutcast, this How-to might be completely worthless anyway and I might have to switch completely to ICECast... which long term might not be a problem.

[Jean-Baptiste Kempf]

No, the support removed is ONLY about Shoutcast Directory listing.

[kdh]

Discovered a bug using VLC streaming to Shoutcast 2.X. Will create a new thread and post details.
