Sound is loaded into memory correctly.
but i have problem with System->createSound() function. It throws FMOD_INVALID_PARRAM but everything should be okay. (compared with FMOD examples)
Thanks for answers.
Everything is okay i just forgot to copy the DLL file^^

I'm trying to write Bytes into a JPEG file, but I don't know the file's format and so the Bytes aren't in the right place of the image after writing into the file.
Does somebody know?
There are several markers that must appear in a JPEG file stream. I believe you can easily find the detailed description of the tags listed below on Internet.
SOI(0xFFD8) Start of Image
APP0(0xFFE0) Application
[APPn(0xFFEn)] (alternative)
DQT(0xFFDB) Define Quantization Table
SOF0(0xFFC0) Start of Frame
DHT(0xFFC4) Difine Huffman Table
SOS(0xFFDA) Start of Scan
DRI(0xFFDD) Define Restart Interval,(alternative)
...Image Stream
EOI(0xFFD9) End of Image
Those markers are followed by lengths in BIG ENDIAN format. You can decode Image Stream that exactly follows DRI using the huffman trees you decoded by DQT. For easier illustration, here are some functions I have written on my own in Java that decodes a header of JPEG, but without doubt there are many better JPEG Java projects on Github that you can refer to.

I very new to Arduino Uno and need some advice....so here we go.
I want to use my Arduino to:
1. read my serial data --received as plain text
2. look for a specific word within a line of data received
3. only transmit/print the complete string if it contains the specific "word"
I found this sketch and it works only if I'm looking for char
// Example 3 - Receive with start- and end-markers
const byte numChars = 32;
char receivedChars[numChars];
boolean newData = false;
void setup() {
Serial.begin(9600);
Serial.println("<Arduino is ready>");
}
void loop() {
recvWithStartEndMarkers();
showNewData();
}
void recvWithStartEndMarkers() {
static boolean recvInProgress = false;
static byte ndx = 0;
char startMarker = '<';
char endMarker = '>';
char rc;
while (Serial.available() > 0 && newData == false) {
rc = Serial.read();
if (recvInProgress == true) {
if (rc != endMarker) {
receivedChars[ndx] = rc;
ndx++;
if (ndx >= numChars) {
ndx = numChars - 1;
}
}
else {
receivedChars[ndx] = '\0'; // terminate the string
recvInProgress = false;
ndx = 0;
newData = true;
}
}
else if (rc == startMarker) {
recvInProgress = true;
}
}
}
void showNewData() {
if (newData == true) {
Serial.print("This just in ... ");
Serial.println(receivedChars);
newData = false;
}
}
I think it is better to use String class methods.
you can get the Data using Serial.readString()
then use the String methods for looking for a specific word.

All,
Currently i'm using Anviz EP300 time attendance machine. I need to download only new records from device.
I'm using following sdk. Click here
There is some method already have in sdk. Which is i used like...
int i = 0;
int Ret = 0;
int RecordCount = 0;
int RetCount = 0;
int pClockings = 0;
int pLongRun = 0;
CKT_DLL.CLOCKINGRECORD clocking = new CKT_DLL.CLOCKINGRECORD();
clocking.Time = new byte[20];
int ptemp = 0;
ProgressBar1.Value = 0;
//If CKT_GetClockingNewRecordEx(IDNumber, pLongRun) Then 'IF GET NewRecord
if (CKT_DLL.CKT_GetClockingNewRecordEx(IDNumber, ref pLongRun) != 0) //IF GET Record
{
while (true)
{
Ret = CKT_DLL.CKT_GetClockingRecordProgress(pLongRun, ref RecordCount, ref RetCount, ref pClockings);
if (RecordCount > 0)
{
ProgressBar1.Maximum = RecordCount;
}
if (Ret == 0)
{
return;
}
if (Ret != 0)
{
ptemp = pClockings;
for (i = 1; i <= RetCount; i++)
{
PCopyMemory(ref clocking, pClockings, CKT_DLL.CLOCKINGRECORDSIZE);
pClockings = pClockings + CKT_DLL.CLOCKINGRECORDSIZE;
insertTimeAttendance(clocking.PersonID, clocking.Stat, Encoding.Default.GetString(clocking.Time), clocking.ID);
ProgressBar1.Value += 1;
}
if (ptemp != 0)
{
CKT_DLL.CKT_FreeMemory(ptemp);
}
}
if (Ret == 1)
{
return;
}
}
}
CKT_GetClockingNewRecordEx that method should be return new records. But it returns all records.
I guess, there is should be one method or config should be mark as downloaded.
Anyone some idea or solution?
Thanks,
Eba
I created the SDK you downloaded (basically written in Vb, and I just convert it to C#)
Actually for the Anviz EP300 device, there is no way you can just retrieve new records,neither retrieve user lists (for example), at list with that SDK.. It has a lot of methods, but unfortunately few of them works fine. You will have to Use CKT_GetClockingRecordEx, instead of CKT_DLL.CKT_GetClockingNewRecordEx
I wrote a solution that involved OpenProcess, EnumProcessModules, GetModuleInformation and GetModuleBaseName, but apparently EnumProcessModules and GetModuleBaseName do not exist in Windows CE! What alternative is there?
I found a way to do this with CreateToolhelp32Snapshot, Module32First, Module32Next, Process32First and Process32Next. First you have to get a list of modules, then search through the list of modules to find the desired address.
#include <Tlhelp32.h>
struct MyModuleInfo
{
BYTE* Base;
HMODULE Handle;
DWORD Size;
enum { MaxNameLen = 36 };
TCHAR Name[MaxNameLen];
};
bool GetModuleList(vector<MyModuleInfo>& moduleList)
{
HANDLE hSnapshot = CreateToolhelp32Snapshot(TH32CS_SNAPPROCESS | TH32CS_SNAPMODULE | TH32CS_GETALLMODS, 0);
if (hSnapshot == INVALID_HANDLE_VALUE)
return false;
MODULEENTRY32 moduleInfo;
moduleInfo.dwSize = sizeof(moduleInfo);
if (Module32First(hSnapshot, &moduleInfo)) do {
MyModuleInfo myInfo;
myInfo.Handle = moduleInfo.hModule;
myInfo.Base = moduleInfo.modBaseAddr;
myInfo.Size = moduleInfo.modBaseSize;
memcpy(myInfo.Name, moduleInfo.szModule, min(sizeof(myInfo.Name), sizeof(moduleInfo.szModule)));
myInfo.Name[myInfo.MaxNameLen-1] = '\0';
moduleList.push_back(myInfo);
} while (Module32Next(hSnapshot, &moduleInfo));
// The module list obtained above only contains DLLs! To get the EXE files
// also, we must call Process32First and Process32Next in a loop.
PROCESSENTRY32 processInfo;
processInfo.dwSize = sizeof(processInfo);
if (Process32First(hSnapshot, &processInfo)) do {
MyModuleInfo myInfo;
myInfo.Handle = NULL; // No handle given
myInfo.Base = (BYTE*)processInfo.th32MemoryBase;
myInfo.Size = 0x800000; // No size provided! Allow max 8 MB
memcpy(myInfo.Name, processInfo.szExeFile, min(sizeof(myInfo.Name), sizeof(processInfo.szExeFile)));
myInfo.Name[myInfo.MaxNameLen-1] = '\0';
moduleList.push_back(myInfo);
} while(Process32Next(hSnapshot, &processInfo));
// Debug output
for (int i = 0; i < (int)moduleList.size(); i++) {
MyModuleInfo& m = moduleList[i];
TRACE(_T("%-30s: 0x%08x - 0x%08x\n"), m.Name, (DWORD)m.Base, (DWORD)m.Base + m.Size);
}
CloseToolhelp32Snapshot(hSnapshot);
return true;
}
const MyModuleInfo* GetModuleForAddress(vector<MyModuleInfo>& moduleList, void* address)
{
for (int m = 0; m < (int)moduleList.size(); m++) {
const MyModuleInfo& mInfo = moduleList[m];
if (address >= mInfo.Base && address < mInfo.Base + mInfo.Size)
return &mInfo;
}
return NULL;
}
i want to find the duration of an audio file of type "amr" without converting it to other audio formats
with any way?
AK
I have coded the following in objective-C to get the duration of a movie. This can similarly be used to get the duration of audio too:
-(double)durationOfMovieAtPath:(NSString*)inMoviePath
{
double durationToReturn = -1;
NSFileManager *fm = [NSFileManager defaultManager];
if ([fm fileExistsAtPath:inMoviePath])
{
av_register_all();
AVFormatContext *inMovieFormat = NULL;
inMovieFormat = avformat_alloc_context();
int errorCode = av_open_input_file(&inMovieFormat, [inMoviePath UTF8String], NULL, 0, NULL);
//double durationToReturn = (double)inMovieFormat->duration / AV_TIME_BASE;
if (0==errorCode)
{
// only on success
int numberOfStreams = inMovieFormat->nb_streams;
AVStream *videoStream = NULL;
for (int i=0; i<numberOfStreams; i++)
{
AVStream *st = inMovieFormat->streams[i];
if (st->codec->codec_type == CODEC_TYPE_VIDEO)
{
videoStream = st;
break;
}
}
double divideFactor;
// The duraion in AVStream is set in accordance with the time_base of AVStream, so we need to fetch back the duration using this factor
divideFactor = (double)1/rationalToDouble(videoStream->time_base);
if (NULL!=videoStream)
durationToReturn = (double)videoStream->duration / divideFactor;
//DEBUGLOG (#"Duration of movie at path: %# = %0.3f", inMoviePath, durationToReturn);
}
else
{
DEBUGLOG (#"avformat_alloc_context error code = %d", errorCode);
}
if (nil!=inMovieFormat)
{
av_close_input_file(inMovieFormat);
//av_free(inMovieFormat);
}
}
return durationToReturn;
}
Change the CODEC_TYPE_VIDEO to CODEC_TYPE_AUDIO and I think it should work for you.
