The VideoLAN Forums

Posted: **11 Jun 2013 16:07**

So I've googled quite a bit and tried the http://wiki.videolan.org/Mosaic examples, but they seem to have some settings that linux accepts which Win7 doesn't so I don't understand the syntax nor the errors I get.

I have a total of 6 remote cameras on 2 (remote) locations. On one location I want to play two local streams, while at the HQ I want to play 3 or 4 for now, maybe 6 long term, and I would like a background image replacing the stream if the stream is down. The streams are HTTP with no audio and they work individually, i.e. if I open just one of them in VLC, it works fine. Few of them have the same resolution, I don't know if that matters - meaning do I need to change the transcoding at the source or can I just define it on the mosaic/client-side?

Anyways, here's my CLI command;

Code: Select all

"c:\Program Files (x86)\VideoLAN\VLC\vlc.exe" -vvv --vlm-conf --mosaic-width=360 --mosaic-height=288 --mosaic-keep-picture --mosaic-rows=2 --mosaic-cols=2 --mosaic-position=1 --mosaic-order=1,2,3,4 C:\Users\Tech\Documents\mosaic.vlm.conf

In the wiki it has a "telnet" and -I parameters as well. I believe -I removes the gui/window of VLC so I changed that with -vvv. The "telnet" command didn't work as VLC would say;

File reading failed:
VLC could not open the file "C:\\telnet". (%m)
Your input can't be opened:
VLC is unable to open the MRL 'file:///C://telnet'. Check the log for details.

I have installed the telnet-client, but there's obviously a syntax error here. Adding a dash or two just gives me an error message from VLC saying it can't parse the command line options. Also, step 2 in wiki tells me to use the file:// option, but I could never get the command accepted unless I removed file:// and just put the filename in there. Guess that's another linux/windows difference.

Anyways, the log from my revised command line gives is as follows;

The wiki says that the background image must be the same size as the stream which it probably isn't so I tried without any background at all but the error-log seemed identical to me.
I'm guessing my VLM file is ok-ish, while the problem lies in my command line. If anyone could give me any pointers, that would be great. I've scoured the net for examples and the documentation seems a bit outdated or incorrect (at least for windows) so I'm fumbling in the dark here.

1) use -Irc instead of -Itelnet
2) C:\Users\Tech\Documents\mosaic.vlm.conf should be just after --vlm-conf

Thanks.

I've been struggling with this for a couple of days and making baby-steps. If someone can help me out with the final steps here, I'd very grateful. I should mention that I've upgraded to 2.0.7.
Currently I get two streams on the background-picture which I resized to 800x600 (only 2/4 active streams at the moment) but the stream only lasts for a very short time (219 blocks/228 frames displayed/59 frames dropped).
1. Why does it stop streaming/receiving? The two streams comes from two remote PCs. "My" PC runs the mosaic command-line, and I open another VLC instance on the same PC to watch it.
Also, it opens two additional Direct3D windows, each showing a stream. I guess this is because of the duplicate-command in the mlv file?
2. How do I avoid that? I only want the VLC window with my background and 2-4 streams, is that possible?
If I open the "client/viewer" and try to watch an existing mosaic stream, it doesn't show anything. If I restart the mosaic-process, the "viewer-vlc" shows the stream.
3. Why does this happen? I guess this proves that streamer in Q1 has stopped, but there's nothing in cmd-window (see below).
If I try to watch the mosaic-stream from a another PC on the same subnet, it doesn't show anything.
4. How can I watch the mosaic stream from another PC?

Another thing I've observed with the mosaic-process is a rather big memory leak. As it runs, it eats more and more memory until it's almost out, then an unhandled exception happens and it crashes. This might be because something happens with the process though, but the CMD window doesn't say anything interesting.

My new command-line;

Code: Select all

"c:\Program Files (x86)\VideoLAN\VLC\vlc.exe" -Irc --vlm-conf C:\Users\Tech\Documents\mosaic.vlm.conf --mosaic-width=1920 --mosaic-height=1200 --mosaic-keep-picture --mosaic-rows=2 --mosaic-cols=2 --mosaic-position=1 --mosaic-order=1,2,3 --udp-caching=800

The background picture is only 800x600 which seems to be what sets the resolution of the mosaic-stream, so I can probably remove the width and height settings.

One final question - is it possible to use HTTP instead of UDP for the mosaic stream?

Posted: **14 Jun 2013 15:19**

Hmm ok so it dies after 10 seconds, which is probably related to the background image and how it doesn't have the durability set. However if I change this line in mlv config:

setup background input C:\Users\Tech\Documents\4TechDiff800x600.PNG

(Like it says in wiki, btw)
to this:

setup background input C:\Users\Tech\Documents\4TechDiff800x600.PNG --image-duration=-1 --image-fps=10

I get nothing (?!).
