Hallo.

i have a own ISP Provider for multicast IPTV Streams and i get a problem using VLC with a max bitrate. Lets say i give VLC a max of 1300kb/s for 1 Stream, my problem now is that VLC sometimes dont use this max bitrate. For example one Stream only show a picture and not a video, like for advertisement and after advertisement done and it show normal video my VLC streaming bitrate goes up till 2000 or 3000 or 4000.
But i have a max connection for my clients for 10.000kb/s and if 2 streams go each over 3000, than its to much and i get pixels.

So is that a bug and what can i do that vlc never go so high i mean if i enter 1300kb/s and it go up to 1700 k but not higher than 2000.

I hope you can help me because its really important for our IPTV project. If you (vlc team) need a big IPTV project than we can help each other.

Can you show a graph?

how which tool can i use to monitor a multicast stream ??

"I hope you can help me because its really important for our IPTV project. If you (vlc team) need a big IPTV project than we can help each other."

if readers of this site are to try and help and understand the problem, its usually a good thing to ALWAYS include your FULL VLC cli lines...

in this case ,BOTH your FULL VLC server lines , and FULL client VLC cli lines....

you say you have a commercial ISP/Co-Location IPv6 connected box(s) ?, and currently Multicasting streaming some test (HD ? IPTV) video streams 24/7 ?

so what is the FULL and DIRECT IPv6 Multicast URL address/port for this test ("elephants dream" and/or "big bunny" AVC ,x264 HD/widescreen encoded ?) data stream , and is it currently reachable from at least the free (to anyone) IPv4 TO IPv6 Multicast tunnels such as http://go6.net/4105/freenet.asp ?


today it seems there are a very few, really inovative AVC HD/widescreen projects and perhaps your's could become such a freenet/IPv6 tunnel connected innovative case today, but given the current state of the streaming server mainstream and not so mainstream sites not even willing to place VLC or x264 at the top of the pile of innovative/basic streaming tools, it seems unlikely Multicast can/will ever go mainstream even if someone does the work produces the code and makes a Multicast tunnel for point to multipoint general purpose generic cross platform VLC use....


rememeber a multicast tunnel is only as good as the end point you, the end user, can point it to, without some a Co-Location site putting up a free multicast tunnel you can connect to and use, your average world ISP consumer cant make use of any such good quality HD/widescreen or even CIF sized multicast protocol AVC you might want to stream, a Multicast Youtube that lets you offline encode your video to HQ18 at least, and upload it free, would be well used today by the masses once such a thing were made available and the simple tools/word got out

on the subject of the state of the streaming marketplace:
two such laughable US sites i tryed to find usable current Multicast streams and server information were

http://www.streamalot.com/
they dont even mention VLC for eather a free (cross platform) streaming server or clients, and even werse, the US "research channel"
http://www.researchchannel.org/help/help_viewing.asp
they stream masses of low quality antiquated MPeg2 unicast video to the masses, but they cant even research enough to make a website that works, its covered in java errors

and they put up a real IPv4 Multicast feed, but its not a direct link and they cant supply Multicast to many IPv4 ISP users, as Multicast is filtered off by the worlds largest consumer ISPS , so much for even basic research, doh!

they cant even be bothered to give out an IPv6 Multicast address or supply a VLC direct feed, and link VLC for use to their non working IPv4 Multicast
feed.....

what s my point, simple, your multicast (tunneled) IPTV project could try and do it right, keep it simple, and yet still supply and Advocate something far better than these clown's try to make you use, and advocate to ALL the worlds masses in time.

keep it simple and basicly cross platform generic, VLC + x264 + free IPv6 tunnel + AVC/AAC inside TS + Multicast (tunnel) + direct IPv6 URL/port + mandatory SAP announces for every single video data stream you put on the wire(less).

Server line:
call "C:\Programme\VideoLAN\VLC086i\vlc.exe" --ttl 20 -vvv dshow:// :dshow-vdev="Videum 1.1 Standard VidCap" :dshow-adev="Videum 1.1 ACap" :dshow-size="" :dshow-caching=200 :dshow-chroma="" :dshow-fps=25.000000 :no-dshow-config :no-dshow-tuner :dshow-tuner-channel=0 :dshow-tuner-country=0 :dshow-tuner-input=0 :dshow-video-input=-1 :dshow-audio-input=-1 :dshow-video-output=-1 :dshow-audio-output=-1 --sout=#transcode{vcodec=mp4v,vb=1300,scale=1,acodec=mp4a,ab=128,channels=1}:duplicate{dst=std{access=udp,mux=ts,dst=239.255.0.1:1234,sap,group="SPORT",name="Haupt"}}

i have no special Client line,
C:\VideoLAN\VLC\vlc.exe udp://@239.255.0.1:1234

My Problem is still there, i get the source from a grabber card with 4 ports, behind each port is 1 receiver. The problem i have is, everytime there is no moving picture lets say for example 10-20seconds a soccer table or a channel show black cause of no signal and i change channel after. Normally i have bitrates between 1300-1400kbs constant, but after that it always go up to 2000 and 3000 and i have no more constant bitrates, i have to stop and press play this solve the problem.

Is there anybody who can tell me a good monitoring tool for windows and multicast, so i get a email when bitrate raises over 2000kbit for example. Im glad for any help

Anybody know how to write a script, like if bitrate goes up to more than 2mbit stop vlc and start back. So script must monitor the traffic of a stream and if bitrates goes up to much it must kill vlc and restart vlc. I find no help with google why vlc always break out of its max bitrate. This is a real big problem for me because i have a max bandwidth for the clients lets say 3 Streams use ca 4,5Mbit and if 1 Stream go up to 4,8Mbit its to much vor the client ISP Line and so vlc streams will start to pixel until i stop and restart VLC. I use version 0.8.6i for server and clients maby that can be the reason ??
