hi

you have to use mosaic and put an image in second stream
result : when you video stream stop for any reason, client will get your image
if video restarts, client will get video because image is behind

works like a charm

problem : since vlc 0.9, it doesn't work well

NIko

hello

did you find a solution about this high cpu usage and fps ?

Niko

hi all,

with 1.0 my tips doesn't work well each time
I have still to use 0.8.6 to be ok

hi all, after using 0.8.6 during very long time as a streaming server with vlm file (with background image with mosaic), I just upgraded one of my ubuntu server in VLC media player 1.0.0-rc2 Goldeneye. so my first comments about 0.8.6i vs 1.0.0-rc2 : 1) encoding in mpeg2 is much better in 0.8.6i ; w...

This sounds good.. is it possible to stream a jpg as background in mosaic ?

=> yes, from what I know : jpg and png

Niko

hello use just mosaic that works well I use it to do the same thing : - stream a background with same size as other video stream - when I receive stream, background is juste behind... and if video stream stops, I get background image => from clients, stream is never broken that's all regards Niko

hello,

can you give us also your html code for your webpage to read your flv stream output ? in resume what we need to create your nice webpages ?
and does it work with live streaming and not files ?

thx

Niko

hello what's your source and in what size/resolution ? I made the same thing and cpu is also out, but h264 eats ressources that's known, I need to change my server too from my side I get video from capture card in 720x576 and I use mosaic to solve problem if source has a problem, I diaplay an image ...

"patch" from x264 project ? or you are talking about other things ?
hope to see "patch" very soon because right now it's a big problem for some of us

regards

Niko

hello

same here, crash in trying to stream with capture card
impossible to use these 0.9 builds to encode in h264
0.8.6 is last good build

and no comments from vlc staff
would be cool to tell us where are you about this problem

regards

Niko

hi all,

can I ask you what VLC version you use on what OS ? because I tried your example but it doesn't work for me on my Ubuntu Server Edition with VLC 0.8.6e

Thanks

Nicolas

Hi all, I have a cpu problem when I try to stream a live meeting in h264. my server is a Xeon 2.8 GHz HT I'm using a vlm conf file : ---------------------------------- new channel1 broadcast enabled setup channel1 input udp://@:1234 setup channel1 output #duplicate{dst=mosaic-bridge{id=1,height=576,...

just tested it and result is horrible !!!
before with udp stream it was ok now catastrophic

downgraded into last 0.8.6

Nico

PS : tested in trying to stream from webcam and from hardware card

hi all, I made several tests to get a good result to stream a video in h264 but it's very difficult to find better options. I'm interested if one of you has all info to put a good stream right now, when I stream video, on receiver side, he gets audio, then after 20-30 seconds, video ... that's toooo...

hello,

something new about this bug ?

because I have exactly the same but with 0.8.6

I try to relay without transcode again and get only audio, and in "logs" tons of "waiting for sps/pps"

thanks

nicolas

hi, I have a problem with a transcode and size I receive stream in udp then I transcode it again for http access. Source is capture card and stream is in 720x576, when I connect myself directly to the source (still with vlc) no problem now when I catch source then I transcode it, then now I open htt...

hello,

now that I found the keys to improve start of stream for clients

can you tell me what the better sizes for GOP (min/max) to improve it again


Thanks

Nicolas

PS : should be cool to get stream like in mp4v (video starts immeditaly) whereas in h264, I wait 20s to get video

hi all, I need help to create CLI command to stream (in http on port 80) audio+video I'm receiving in UDP (unicast) and in the same time, catch this stream then reencode it at low birate and stream it in http on port 81 in resume : my server will get : it will receive stream in UDP it will stream in...

ok I found, it was :
max/min size of GOP

Thanks

hi, I would like to use VLC to stream a meeting where about more than 100 users should participate from an other place, so with VLC client. My problem is bandwidth usage : I know that I can add VLC relays but how can you dynamically forward a client to the right VLC server, VLC should make tests to ...

... and how can I change I frames to push enough to get video quickly ?

hello, sorry can you explain a bit more what you mean ... I'm not an expert what I know is : my stream is h264 for video and mp4a for audio ... and when client connects, he has voice quickly but no video, but after more than 30s video appears how can I help you to find a solution ? maybe I forgot so...

hi all, I configurated vlc to stream video + audio from my webcam I chose h264 in video codec but I have a big problem from client side, when client connects in http to my vlc, stream is very long to appear (about 30s or 1minute) he seems to me that problem is h264 because when I choose mp4v, no pro...
