Thank you so much. I was not aware of this database.

Not sure why there would be a 16 multicast stream limit for 2N.? Maybe there is some communication from the end point going back to the 2N.?? But at least the test multicast I have set up (using UDP), there is no data going back to the the server from the end points.? I would use Wireshark to see what 2N is doing on their stream and in particular, if any data is being sent back to 2N.

I've generated my own multicast stream by playing a video on my laptop.? I use it mainly to test if I have my IGMP snooping, Querier, and multicast router settings correct.? There is really no theoretical limit to the number of devices that can receive the multicast stream.? But your need to consider these:

1) You should have IGMP snooping enable.? Otherwise, everyone on the network will be bombarded by the multicast stream.? Also if you don't have IGMP snooping enabled, it can lock up your network switch (at least I had this happen with a DM-NVX-351 on the network if I screw up).

2) You don't exceed the bandwidth of your switch.? Each device receiving the multicast stream will get you closer to your switches bandwidth limit.

Generating a mulitcast stream is pretty easy (at least in LInux) using ffmpeg.? On the multicast server (my laptop), I execute something like this:

ffmpeg -re -i MyVideo.mp4 -vcodec mpeg4 -f mpegts udp://239.255.0.8:23000

Note you need to let port 23000 (in this case) pass the firewall on your server.

For the receiver (another laptop), I execute:

ffplay udp://239.255.0.8:23000

I am sure there are other ways to generating a multicast stream for testing.? But I find these commands work well for me.? But there is absolutely no security on the stream.? Anyone on the same subnet could receive the stream.? Possibly you could encryption the stream if you want to limit who can or cannot view the stream.

While I am not that familiar with RSTP, per Wikipedia, RSTP allows the clients to control the stream (play, pause, etc) and uses TCP instead of UDP.? So I cannot really see how RTSP could do a pure multicast stream.

Hello,

?

I am a new dev to Crestron software and I have some basic questions about HTTPs requests! I am trying to send a url-encoded HTTPs POST request following ?and then I'd like to save the cookies from the response.?I'm confused on whether I need to make a separate GET request like in the example or if a single POST request would suffice. I'm also having some trouble formatting a proper POST request and I am repeatedly receiving a 403 error.?

?

The following is a snippet of my current code. Am I properly structuring the request? Am I missing something important? Do I have extra unneeded information? Am I even going about this the right way??

?

HttpsClient httpsClient = new HttpsClient();

HttpsClientRequest httpsRequest = new HttpsClientRequest();

? ? ? ? ? ? HttpsClientResponse httpsResponse;

?

? ? ? ? ? ? //Disable certs and verbose

? ? ? ? ? ? httpsClient.HostVerification = false;

? ? ? ? ? ? httpsClient.PeerVerification = false;

? ? ? ? ? ? httpsClient.Verbose = false;

? ? ? ? ? ? httpsClient.AllowAutoRedirect = true;

?

? ? ? ? ? ? CrestronConsole.PrintLine("Disabled certs and allowed redirect");

?

? ? ? ? ? ? try

? ? ? ? ? ? {

? ? ? ? ? ? ? ? httpsRequest.RequestType = Crestron.SimplSharp.Net.Https.RequestType.Post;

? ? ? ? ? ? ? ? httpsRequest.Url.Parse(url);

? ? ? ? ? ? ? ? CrestronConsole.PrintLine("Parsed URL\n");

?

? ? ? ? ? ? ? ? httpsRequest.Header.SetHeaderValue("User-Agent", httpsClient.UserAgent.ToString());

? ? ? ? ? ? ? ? httpsRequest.KeepAlive = true;

? ? ? ? ? ? ? ? httpsRequest.Header.SetHeaderValue("Content-Type", "application/x-www-form-urlencoded");

? ? ? ? ? ? ? ? httpsRequest.Header.SetHeaderValue("Host", "10.1.10.0");

? ? ? ? ? ? ? ? CrestronConsole.PrintLine("Set Content Type and Host\n");

? ? ? ? ? ? ? ??

? ? ? ? ? ? ? ? string command = str2JSON("login=" + login + "&" + "passwd=" + password);

? ? ? ? ? ? ? ? //string command = "login=" + login + "&" + "passwd=" + password;

? ? ? ? ? ? ? ? httpsRequest.ContentSource = ContentSource.ContentString;

? ? ? ? ? ? ? ? httpsRequest.ContentString = "";

? ? ? ? ? ? ? ? httpsRequest.ContentString = command;

? ? ? ? ? ? ? ? httpsRequest.Header.SetHeaderValue("Content-Length", "24");

?

? ? ? ? ? ? ? ? CrestronConsole.PrintLine(command + "\n");

? ? ? ? ? ? ? ? CrestronConsole.PrintLine("Set Body\n");

?

? ? ? ? ? ? ? ? httpsResponse = httpsClient.Dispatch(httpsRequest);

? ? ? ? ? ? ? ? CrestronConsole.PrintLine("Sent Request\n");

?

? ? ? ? ? ? ? ? responseCode = httpsResponse.Code;

? ? ? ? ? ? ? ? CrestronConsole.PrintLine("POST Response Code:" + responseCode.ToString() +"\n");

?

?

? ? ? ? ? ? ? ? string[] subStrings = httpsRequest.Header.ToString().Split(',');

? ? ? ? ? ? ? ? foreach (string str in subStrings)

? ? ? ? ? ? ? ? {

? ? ? ? ? ? ? ? ? ? CrestronConsole.PrintLine(str);

? ? ? ? ? ? ? ? }

? ? ? ? ? ? ? ? string[] subStrings2 = httpsResponse.ContentString.ToString().Split(',');

? ? ? ? ? ? ? ? foreach (string str in subStrings2)

? ? ? ? ? ? ? ? {

? ? ? ? ? ? ? ? ? ? CrestronConsole.PrintLine(str);

? ? ? ? ? ? ? ? }

?

? ? ? ? ? ? ? ? return command;

? ? ? ? ? ? }

?

?

public string str2JSON(string urlString)

? ? ? ? {

? ? ? ? ? ? urlString = urlString.StartsWith("?") ? urlString.Substring(1) : urlString;

? ? ? ? ? ? string resultString = "{";

?

? ? ? ? ? ? string[] urlKeyVal = urlString.Split('&');

?

? ? ? ? ? ? foreach (string kv in urlKeyVal)

? ? ? ? ? ? {

? ? ? ? ? ? ? ? string k = kv.Substring(0, kv.LastIndexOf('='));

? ? ? ? ? ? ? ? string v = kv.Substring(kv.LastIndexOf('=') + 1);

? ? ? ? ? ? ? ? resultString += "\"" + k + "\"" + ":" + "\"" + v + "\",";

? ? ? ? ? ? }

? ? ? ? ? ? resultString = resultString.Substring(0, resultString.Length - 1);

? ? ? ? ? ? resultString += "}";

?

? ? ? ? ? ? return resultString;

? ? ? ? }

Sorry if this has already come up but after a short search I could not find many resources for an HTTPS Post Request. If someone could point me in the direction of a good example I would appreciate it.?

Port is 33336d.? Like Heather, I'm using the?Sony UBP-X1000ES IP module to control 3 players in a project and it works fine.? In this particular project, I would know about it if it stopped working at any point.

Yes I’ve upgraded CP4N to 2.500 released on April 12, problem still there.

I was going to post a question about this. I would love to hear what solutions we might have for using IR with this new AppleTV, if this is more than a specific site issue...
I was using CEC with DM/NVX, which does work great (though I have had a couple times where control has locked up and needed a card reboot),
but I've defaulted to IR control since a) It always works and b) a press+Hold on the Menu Button will bring the unit back to the main menu (You can't P+H with the CEC and the MainMenu button does weird things now)

What IP port is used to communicate?

If you are using DM - use CEC, works flawlessly

Have 5th Gen Apple TV using Crestron Gen 4 IR driver and it is triple pulsing IR commands. Have never had this issue with this Crestron Gen 4 driver on either 2 or 3 series processor and DM systems. Has anyone else had this issue?
Is there a newer updated IR driver for the Gen 5 boxes?

Shane, Any recommendations on those bars?

Sorry, i should have mentioned were using DM_OutPut, not HDMI? In all installations.

DM Output to Digital Link is how its wired; my CEC serial signals are only present on the DM Outputs CEC transmit and received. This setup is working on the 150's, but strangely not on the 350?

I was just hoping someone else may have encountered this and/or has recommendations that I may have missed?

thanks again
Bryan

Looking at the link you gave, question #4 says its NOT CEC compatible.

Hi everyone,

I was hoping someone can help me with this problem, I have a DMPS 350 that will not communicate via CEC with a Panasonic Projector?? I have a exact setup in other boardrooms using a DMPS-150 and CEC is working fine?

Ironically, on the Panasonic?? ? site the DMPS-150 was the crestron unit tested?? My assumption is the DMPS-350 would also work with CEC? Am I missing something?

I've left the AV Framework on the processor and added a my own program in slot 2.? As mentioned, same " carbon copy" works in the DMPS-150's?

Has anyone encountered this or similar ?? I have tried TBS but to no avail?

Thanks in advance
Bryan

Hi All,

Having some issues with controlling an Ubicast Miris Plus lecture capture. rs232 is enabled and the commands are the same commands that work in another room. I've never had to set one up from scratch so I'm second guessing my program.?

Commands:

Record: * RECORD \x0D

Stop Recording: * STOP?\x0D

Pause Recording: * PAUSE?\x0D

Resume Recording: * RESUME?\x0D

Baud Rate:?
9600 // 8 / 1 / N

Has anyone had any dealings with controlling these units? If so, any help would be greatly appreciated

I asked 2N about the exact scenario the OP is dealing with, and they also said to use the "DOOR_STATION" string as the stream URL.? This supposedly uses the embedded video stream of the incoming SIP call, as opposed to each panel requesting a unicast RTSP stream.? When I tested it on-site, it seemed to work as described, but I was only able to monitor 1 panel at a time, and I can't be sure the panel I was looking at wasn't one of the lucky ones that was able to view the video while there were other panels somewhere ringing with no video displayed.

It didn't occur to me at the time, but does this mean that IGMP Snooping needs to be enabled on that subnet so that the switch knows which ports are asking for the multicast stream?? Or maybe all ports are getting flooded with the multicast SIP call coming in, but it isn't consuming enough bandwidth to be an issue for devices that aren't interested in that traffic?

Hi All,

Anyone else here experiencing issue with managing GUI extenders in SIMPL?? No matter what program I open, that I have done in the past, when I go to browse for the SGD, the dialog just sits and spins for three or four minutes until it will let let me browse to the location for the file.? I have restarted my PC multiple times and I installed the current version of the software and it stills does this everytime.

TIA,

Steve

I currently have a 4k Sony BluRay Player with a standard def DVD connected to?the input of a DMC-4K-HD-HDCP2.? From the input card I am taking the HDMI Out directly to an HDMI input on a Yamaha TSR-700 AVR.? The cables are all Crestron.? Is there any special configuration needed for connecting the HDMI output (Thru) from a DM Input Card to an AVR?? Right now I get an "HDMI Output Unauthenticated" error when I connect between these two HDCP 2.2 devices.? In DMTool it shows the content coming in from the content player is HDCP1, even when I force HDCP2, so that didn't change anything.? Directly connecting from the BD Player to the AVR works just fine.?

From Crestron's website:
HDMI? Pass-Through
Every DM switcher input card includes an HDMI output port, which can be used to pass the input signal through to a local audio processor or video monitor, or to feed a second DM switcher for output expansion purposes.


Is it possible the BD player has only a single HDCP key available and it is taken by the input card, leaving none for the passthrough?? What's the best way to troubleshoot this as I don't have any visibility into this connection (at least I can't find any in DMTool).? Any thoughts would be greatly appreciated!? ?
