Does any one have codes to transfer any video file from one machine to another through socket program..please help ...:confused:
Offline
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)
Offline
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.

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

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.
Offline
hi jeremy ...now i am able to transfer the files..thanks..:cool:

Hi,
I'm brazilian and i'm written just to thank you Jeremy for you source code to file transfer with sockets. It helped us a lot.
Thanks.
Dionei.

can u help me with the code for splitting(into smaller packets) & transferring a video file(any kind) from server to a client implemented in java using Socket programming.
Even i need codes for sending video files using socket programming.. can anybody help me?
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.

}Hi jeremy,
how can i implement that TCP file transfer code(what u have implemented before ) over UDP to transfer any type of file..
how do i execute the code provided by jeremy on windows 7.I am new to socket programming and i have to transfer a video file from server to client which are hosted on the same pc.thankful for the replies.
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?
Offline
will visual studio compiler work?
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...
Offline
is the code provided above correct?i am getting errors when compiling in turbo c++ and am not able to run it.kindly help.
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...
Offline
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.
i am compiling same code under linux in ubuntu
getting error in connect function on send side
using two different sysytem both are ubuntu
not able to share file between them
but on single system with two terminal it works file need help
