Remoting

OK, well, that does make things more messy. If it's not a web based UI ( which I assume by what forum you're in ), then I'd imagine you'd send the videos down to the client, and you'd use a connection ( perhaps through WCF ? ), to send messages to all the clients telling them when to pause, when to play, and from time to time to tell them where the admin video is at so they stay in synch.

It’s a scenario in which the instructor I will play a training tutorial on the system(server system) and the 25 students will be watching on their system(client), instructor can pause, play, stop. I think I am not able to explain u properly :( sorry its Windows base will be working on Lan

OK, that's exactly what I thought.

OK, well, being on a LAN probably makes it easier to establish TCP connections to pass data around. I still think you want to give everyone a program which can play the video, but that only plays/pauses/stops based on the messages coming from the instructor machine.

yes, client will only have a option to close the file, that's it So what should i use , Remoting with tcpchannel ? and how to send the video file,and play it(serialization? )
I would think if you're just on a LAN, you would put the videos onto a shared location and transmit just that file location to the client. To be honest, the amount of network traffic will be so small, that I don't think it will matter what you use to communicate. Remoting will work just fine.

thanks for the help.will be needing ur help in future in these prject. thanks u means to say the file which is beeing played in the admin first should be stored on the shared folder, and from the client use this file from shared folder and play it ? for these does we need serialization ? can u suggest me any references or example for this. thanks

I have no idea why you keep refering to serialization because it has nothing to do with anything you are discussing. I am saying, if you're on a LAN, then the files can be on a folder that all the students can view. So you send a file path through your remoting connection, and then connect to the file, or copy the file from the central location, just with a File.Copy command.

I think I'd want to do a test first, just playing the video on 25 machines simulaneously. At about 640*350 resolution, you will be streaming about 3Mbyte of data per second from the same server - with network overhead etc, you may get stuttering, especially if you are not on a dedicated or fastish network.

CG did say to copy the file first to local drive that would resolve that issue (k it would create a burst at the start but once playing the only network traffic would be the instructions from the server)

He did, but then sugested a path they could all get at. If they are held locally then there is no problem, it's a relatively simple MediaPlayer and sockets problem. I just felt that if it was a single copy being read (which is obviously a whole lot easier for configuration and control purposes) then test it first!

You need the path to know from where to copy the file So server sends network path to video file to all clients, clients use this path to copy the video file from the server to there local drive. After that clients use the local copy of the video file to play it. (At least that's how I understood it)

If I was one of the poor sods on the course, that would annoy the hell out of me, particularly if I was paying with my own money: 1) Start training video 2) Wait a few minutes while we copy the file over the network. 3) Video starts. Copy them all to local HDD: no delay, no stutter, no problem. You can then control it in MediaPlayer (or whatever) via sockets so the trainee does not need to go anywhere near the video file itself. If the tutor is that paraniod, he can copy them ready in preparation for the days lesson.

Didn't say it wouldn't be annoying ;P I guess it depends on how large the files are. But even in your scenario the logic still holds, minus the copy part. And provided the tutor put the files all in the same location (something like c:\videos). I guess the best option here would be: Go buy a projector ;P
