Sensoray 819 Windows SDK - Manual (Page 15)

Demo Applications and Examples
C# Visual Studio .NET Demo
A full feature demo application written in C# .NET is provided. This includes a class file to
communicate with all the functions in the DLL. The different channels may be controlled by right-
clicking on the channel of interest.
C source code
The following code demonstrates the ease of use for the SDK.
JPEG capture
Opens channel 2 in JPEG streaming mode and saves the first 30 JPEG files to disk (in the temp
directory).
int _tmain( int argc, _TCHAR* argv[])
{
int channels;
S819_CHAN s819chan;
HCNODE hcnode;
BUFFER buf;
int rc;
FILE *fin;
int i;
char name[60];
rc = S819_Enumerate(&channels);
S819_SetMode (0, &s819chan);
hcnode = S819_CreateCnode();
S819_AttachStreams(hcnode, 2, SMASK(STREAM_JPEG));
S819_StartStreams(hcnode, 2, SMASK(STREAM_JPEG));
for (i = 0; i < 30; i++) {
S819_WaitBuffer (hcnode, &buf);
sprintf(name,
"c:\\temp\\test%d.jpg" , i);
fin = fopen(name, "wb" );
fwrite(buf.buf, 1, buf.length, fin);
fclose(fin);
}
S819_StopStreams(hcnode, 2, SMASK(STREAM_JPEG));
S819_DetachStreams(hcnode);
S819_DeleteCnode(hcnode);
S819_Close();
return 0;
}
H.264 Recording
Saves one file as raw H.264 output (test0.264) and another as ISO 14996-14 compliant .mp4.
