Re: socket program to transfer Video file

What do you mean?

Do you want to transfer files between different hosts via a network? (scp, ftp)

Do you want to stream video data and display it on different hosts? (vlc)

More information, please... would using a pre-existing program like Samba or FTP or scp or rsync suit your needs?  Or are you looking for code to include in your own program?  What about the routine is video-specific?  Are you wanting to stream video across the network, or just transfer a file from one computer's hard drive to another computer's hard drive?

Re: socket program to transfer Video file

dear jeremy,
  Thanks for the reply .. actually i first want to break a video file into  parts
and send these parts one by one  to another host through socket.

Re: socket program to transfer Video file

Well, below is some code that demonstrates transferring a file over a TCP connection.  Note that I only compiled and tested this code under MacOS/X; it should work under Linux and Windows but might require some minor tweaking on those platforms.

To run it, open up two shell windows (either both on the same machine, or on different machines).  In one, run it like this:

./a.out receive filename_to_create.txt 9999

Then, in the other, run it like this:

./a.out send filename_to_send.txt 127.0.0.1:9999

(if the receiver is on a different machine than the sender, replace 127.0.0.1 with the IP address of the receiver machine).

If all is successful, you will see output in both windows indicating data is being transferred, and at the end, both programs will exit, and there will be a file filename_to_create.txt on the receiving machine that is identical to filename_to_send.txt is on the sending machine.

Hope that helps,
Jeremy

Re: socket program to transfer Video file

dear jeremy,
   A lot of thanks...one more question i have previously tried a similar type of code ..it was sending text file easily from server to client but is it possible to send video file , i mean in your code where file name is to be mentioned if i write
name of any video file will it do.

Re: socket program to transfer Video file

For those of you (us) who are more amateur when it comes to coding, this thing can be done very easily through any kind of cloud computing service. I won't name the one I use due to forum regulations, but it is as simple as putting the file in a folder that can be shared by as many systems as you want. Less tedious, and quicker depending on file size.

Re: socket program to transfer Video file

Guys, if you want help then you need to ask specific questions.

Ram: Just post your code and tell us what the problem is. We'll try to help even if it's Java code.
Start a new thread for this.

Maharathi: Jeremy posted some C++ code to transfer any type of file.

Re: socket program to transfer Video file

Well, you'll first need a C compiler (C++ will probably suffice as well)...  It looks like he's already coded in some Win32 support, so it may not need anything other than that to get it running...  But, I couldn't tell you, as I haven't used any version of Windows since Win95, and don't plan on ever using any ever again in my life!  But, maybe someone else here who has the misfortune of running Windows and has a compiler onhand already can whip you up a compiled binary?

Re: socket program to transfer Video file

I really have no idea...  Like I said, I don't use Windows and haven't for ages, so I'm blissfully unfamiliar with anything in that realm of horror...  But, assuming it's a C/C++ compiler, I can't imagine why it shouldn't work...

Re: socket program to transfer Video file

What errors exactly?  I just tried compiling it with GCC, and I had to add #include's for two headers: <signal.h> and <stdbool.h>...  Without those, it does indeed complain...  But, with those added, it seems to compile cleanly...

Re: socket program to transfer Video file

it is showing errors in header files like<sys/socket.h> <netinet/in.h> and <unistd.h>.it is showing that it cannot open source files.
i think it will work well with unix based operating system.for windows we need to program it differently.thanx anyways.

What error, exactly?  Are you sure you're specifying the correct IP address and port#?

Another possibility is that local firewall rules are forbidding the connection...  I believe Ubuntu has some default firewall rules in place...
