I have a working encode demo app that is modified to work on my custom
hardware.
It compiles and runs, encodes the video with the codec engine, etc.
But now I am trying to simply clean it out and make it into a library to use
in a streaming application.
I changed very little besides the organization of the source code and built
an interface so another application can control it and get the frames from
it instaed of them being written to disk.
I did not even touch the part that initializes the device, codec engine,
encoder, and capture device.
But it does not run and exits with an error at VIDENC_Process.
If I remove VIDENC_Process, the program runs and captures raw frames and
then, of course, does not encode them.
So the problem seems completely centered around the way I call
VIDENC_Process or the parameters that are being passed to it.
Here is some debug trace:

Here is the encodeVideoBuffer function that calls the VIDENC_Process and
always fails.
static int encodeVideoBuffer(VIDENC_Handle hEncode, char *inBuf, int
inBufSize,
char *outBuf, int *outBufSize)
{
XDM_BufDesc inBufDesc;
XDM_BufDesc outBufDesc;
XDAS_Int32 inBufSizeArray[1];
XDAS_Int32 outBufSizeArray[1];
XDAS_Int32 status;
VIDENC_InArgs inArgs;
VIDENC_OutArgs outArgs;
inBufSizeArray[0] = inBufSize;
#ifdef WIDESCREEN_LCD
outBufSizeArray[0] = LCD_FRAME_SIZE;
#else /* !WIDESCREEN_LCD */
outBufSizeArray[0] = D1_FRAME_SIZE;
#endif /* WIDESCREEN_LCD */
inBufDesc.numBufs = 1;
inBufDesc.bufSizes = inBufSizeArray;
inBufDesc.bufs = (XDAS_Int8 **) &inBuf;
outBufDesc.numBufs = 1;
outBufDesc.bufSizes = outBufSizeArray;
outBufDesc.bufs = (XDAS_Int8 **) &outBuf;
inArgs.size = sizeof(VIDENC_InArgs);
outArgs.size = sizeof(VIDENC_OutArgs);
/* Encode video buffer */
status = VIDENC_process(hEncode, &inBufDesc, &outBufDesc, &inArgs,
&outArgs);
if (status != VIDENC_EOK) {
ERR("VIDENC_process() failed with a fatal error (%ld ext: %#lx\n",
status, outArgs.extendedError);
return FAILURE;
}
*outBufSize = outArgs.bytesGenerated;
return SUCCESS;
}
Any help would be appreciated. I have gone over this so many times and it
just looks the same as the encode demo which is working fine.
Thanks,
