Gstreamer Problem, Sound Converter

I have a typical requirement, I want to have a converter module, that can convert UDP packet to TCP packet. And I need to do it before the packet can be processed in IP layer.

I will explain this complete scenario using an example

Lets say we have 3 machines A, B and C.

A sent an UDP packet
B received UDP packet
At B, when packet is being given to IP layer (from Link / MAC / Ethernet layer) , I want to get hold of packet. I want to delete the UDP and IP header in packet. I want to add TCP and IP header (assuming C is the destination host).
Now from B machine, packet is sent to C machine

Can somebody help me how this can be done. I am using linux machines.

Though libpcap can be one of the option (from wireshark), but it is not suitable for me because of performance reasons. I want a very light weight solution for this problem.

Dear All
Can you please do me favor and let me know how can I convert .wav sound files to .gsm format as I have an application for this usage ? Please be informed that I have made use of the sox utility for this purpose , as the followings , but it didn't get through :
#sox FR00003.wav -r 8000 -c 1 FR0003.gsm resample -ql
Can you please let me know what is the problem in my case ?

Working with CentOS 6.6. When logged on as root, sound works fine and 'Preferences -> Sound -> Hardware' shows the 'Internal SOund" device. When logged on as normal user, no sound and 'Preferences -> Sound -> Hardware' offeres no choices. What do I need to twiddle to enable sound for normal (i.e. non-root) users?

Hi, I am new in Slackware. I installed it with KDE.

But there is a good new. When I run "aplay -D plughw:0,0 /usr/share/sounds/alsa/Front_Center.wav" (A command that I found surfing in Internet) The pc give me sound.


In no other way I have sound. What can I do? Thanks a lot

Sorry for my basic english

I have installed a new Debian OS to try out the xfce desktop.
My radeon hdmi sound card needs non-free drivers and so I have no sound.
On my previous debian install with gnome desktop, I found a number of changes I had to make to get the sound working.

I have done all this with this new install with xfce.
However, one thing I haven't done yet is to change the System settings-Sound settings to use the hdmi sound card.
The problem is the xfce desktop doesn't have an icon for sound settings under System settings.

This is a bit weird. So I'm wondering if xfce has installed correctly or if it's missing a package so the System sound settings will show up.
Does anyone know what's going on?

I just downloaded zorin. I cannot find the sound control, nor do I hear any sound.

I tried to use the search option on this forum but had trouble finding the thread I was looking for.

Thanks in advance


Update: Ok, i got the volume control to show up on the panel, down next to the clock. Everything is turned all the way up, when i pull up pulse audio i can see the sound meter fluctuating while i play a video, but there is no sound coming out of the speakers.

How do i get sound?

Thanks again

Hi
I have installed Linux Mint 17 Mate. I worked very well for many many days. However, today suddenly the sound system has stopped making any sound. Linux Mint is producing any sound, whatever audio/video player I use. How can I fix it?
Update: The sound system in Mate Control Center is making sound, however VLC/MPlayer are not producing any sound. But audacious is making sound.
PS. Other OSes are producing sounds correctly.

hello,
I installed an ATI card into my pc, now the sound is gone. I suppose this is due to the position of that new card which is now "0" (when I start alsamixer, I see the sound default is "HD-Audio Generic" with "Chip: ATI R6xx HDMI". I dont have a screen on the HDMI. I just want to take the "Intel ICH6" with "Chip: Analog Devices AD1981B" as the default card as per previous installation.

What should I do?

cat /proc/asound/cards
Code:

 0 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xf0620000 irq 42
 1 [ICH6           ]: ICH4 - Intel ICH6
                      Intel ICH6 with AD1981B at irq 21

Thanks.

hello,
could somebody inform you to setup again the sound?
Thanks.

I am trying to build a socket to retrieve the ethernet packets from ecu. When i run my code on windows there is no problem and the code runs correctly. But when i run my code on Linux it gets stuck at s.recv(65565). I have already set static ip in /etc/network/interfaces as follows: iface eth0 inet static address 160.48.199.91 netmask 255.255.255.0 gateway 160.48.199.254

I tried a simple code of socket on raspberry pi. but it still gets stuck at s.recv(65565). I also tried to implement the program using multicast. but the problem is that when i create a socket for icmp protocols then I could see the data from the ECU after using command "ping -I echo 239.192.255.251" in another terminal. (where 239.192.255.251 is the multicast address) But when I change the socket protocol type to udp, tcp or raw then it again gets stuck at s.recv().

Imp: When i run the "netstat -s" command in terminal then i could see that there are 0 messages received for udp and tcp. But in Wireshark i could see the udp messages from ECU. Is linux killing all the udp and tcp packets ? How should i solve this ?
(complete setup is connected as: ECU ---> Media converter ---> Raspberry Pi. There is no LAN, no firewall, no internet)

Could anyone please help me with this problem ?
