Hello All
I am writing an application to store the RTP packets payload to audio files.
Now I am working on G.729 Codec. I am storing decoded G.729 payload in .WAV file. But the audio converstation is not stored properly.
I hope Decoding is done properly (Function is not returning ERROR). Extracting the payload is proper.
WAV file header details what I am stroing
Compression Code : 1 (PCM/uncompressed)
Channel: 1
Samples Per Sec: 8000
Bits per sample: 16
Let me know is my procedure is correct? After decoding let me know what is the format of the audio we get?
My application works fine for G.711 codec.
Thanks for your time
Ravi

Hai,could any one pls help me out.....
I have statically created a splitter window with 2 views one is derived from CTreeView and the other from CListView.Then i have managed to insert items into the tree view retrieving from the database. Now i want to insert some columns into the listview but i couldn't do so since the style of the list view is to be LVS_REPORT . But, initially the style is LVS_SMALL.I don't find any way to change this style property using msdn functions.
Please tell me either how to change the style property or how to insert the columns into the listview as above.

Change the style:
m_List.ModifyStyle(0,LVS_REPORT);
Insert a few columns:
m_List.InsertColumn(0,"abcd");<br />
m_List.InsertColumn(1,"efgh");
this is this.

I need to display some visualizations base on output sound from speaker.
How could I do that? (No DirectX)
|
|
|
|
|
Get a flipchart and a pen. Open the flipchart and pump up the sound. Then, each time you hear a drum, move your pen up and down, while, during the song, slowly moving your pen from one side of the chart to the next.
If you do not want to use DirectX, try using an A/D-converter to feed your data back to the PC (USB or Legacy Ports).
Cheers,
Sebastian

If I was you, I would try, lets say, the Audacity source. Audacity is an open-source sound/wave editor/filterset, which might save you a lot of work.
They should do something like that somewhere.
If I was to record my own sound on the computer, I would retrieve the input from "Stereo Mixer" (which should also contain every sound your computer currently is playin, because it remixes the output stream into the input stream.
Cheers,
Sebastian

I have created a charater pointer which points to
a string . I need to copy an existing string in the
char pointer i created so i did this
In my class the code is as
char *m_FileName;<br />
m_FileName=new char[strlen(FileName)]; <br />
strcpy(m_FileName,FileName);
In the destructor of the class
<br />
~Class_temp()<br />
{<br />
if(m_FileName!=NULL)<br />
delete []m_FileName;<br />
}
I get a error at the delete keyword ,
Damage After normal Block 0x00000034
am i wrong some where

This won't work coz it's an array of memory.

When using new[] you MUST always use delete[], no matter if you allocate an array of char.
|
|
|
|
|
FileName is a zero-terminated string and strlen returns the number of charachters WITHOUT counting the '\0' char. When you allocate your new string, you need to allocate for one extra character otherwise when you make the copy, the ending zero will be written outside the boudaries of your allocated memory.
Instead of
m_FileName=new char[strlen(FileName)];
Write:
m_FileName=new char[strlen(FileName)+1];
|
|
|
|
|
You should allocate space for one more character than the length of the string:
m_FileName = new char[strlen(FileName)+1];
Also you should initialize m_FileName to NULL in the constructor:
m_FileName = NULL;
this is this.

Yeh i initialised
m_FileName = NULL;
but thanks for the suggestion that i should
add one more memory space for termination
charater .
But it dont work to solve my problem

Hello,
After the modification of the +1, your code should work. Are you modifying the string elsewhere?

Also either call
memset(m_FileName,0,(strlen(FileName)+1));
after the new,
or call
m_FileName[strlen(FileName)] = '/0';
after strcpy.
These sort of issues are commonly caused by the program not seeing the end of the string and it overruns it's buffer.
Another possible issue is if you are assigning a pointer to that string elsewhere that is still using it. Check the debugger to ensure anything that needs to reference the string stored in m_FileName after it's deleted has made it's own copy.
eg. code like this is BAD
class MyClass
{
private:
char* mystring;
public:
void SetMyString(const char* const newstring) { mystring = newstring; }
};
void somefunction()
{
MyClass mc;
const char* conststring = "test me"
char* addstring = new char*[strlen(conststring)+1];
memset(addstring, 0, strlen(conststring)+1); // strlen(conststring)+1 could be assigned to an integer
strcpy(addstring, conststring);
mc.SetMyString(addstring);
delete[] addstring; // BAD - because mc now contains an invalid pointer!!!!!
}

Nope. strcpy will copy the terminating zero so you don't need to do it yourself.
