Hi all,
Using the example code capture_encode from OMX, I need to write and store the video captured in a SATA SSD.
/* ========================================================================== */
/**
* IL_ClientOutputBitStreamWriteTask() : This task function is file writetask for
* encoder component.
*
* @param threadsArg : Handle to the application
*
*/
/* ========================================================================== */
void IL_ClientOutputBitStreamWriteTask (void *threadsArg)
{
//unsigned int dataRead = 0;
OMX_ERRORTYPE err = OMX_ErrorNone;
IL_CLIENT_COMP_PRIVATE *encILComp = NULL;
OMX_BUFFERHEADERTYPE *pBufferOut = NULL;
static unsigned int frameCounter = 0;
encILComp = ((IL_Client *) threadsArg)->encILComp;
/* use the initial i/p buffers and make empty this buffer calls */
err = IL_ClientEncUseInitialOutputResources (encILComp);
while (1)
{
/* Read filled buffer pointer from the pipe */
read (encILComp->outPortParams->opBufPipe[0],
&pBufferOut, sizeof (pBufferOut));
/* write data to output file */
fwrite (pBufferOut->pBuffer,
sizeof (char),
pBufferOut->nFilledLen, ((IL_Client *) threadsArg)->fOut);
frameCounter++;
if((frameCounter == encILComp->numFrames) || (gILClientExit == OMX_TRUE))
{
frameCounter = 0;
semp_post(encILComp->eos);
pthread_exit(encILComp);
}
/* Pass the input buffer to the component */
err = OMX_FillThisBuffer (encILComp->handle, pBufferOut);
if (OMX_ErrorNone != err)
{
/* put back the frame in pipe and wait for state change */
write (encILComp->outPortParams->opBufPipe[1],
&pBufferOut, sizeof (pBufferOut));
printf (" waiting for action from IL Client \n");
/* since in this example we are changing states in other thread it will
return error for giving ETB/FTB calls in non-execute state. Since
example is shutting down, we exit the thread */
pthread_exit (encILComp);
}
}
}
The code above is the example code of the writing task. It writes captured frames in a output file, but, this file is located in memory or disk or in a I/O hard drive?
The application I need to modify, needs to store data (write in a SATA SSD) and then read it (playback the video frames, the wrote file).
Any idea, suggestion or advice is needed.
Regards,
Inigo
