I have a couple of basic questions.
a) How does one access the pixel information, in the buffer.
I am using the dm6467 board and running the encode/decode. I have reproduced
the code context in the demo for reference below:
-------------------------------------------------------------------------------------------
/* Get a buffer from the capture driver to encode */
if (Capture_get(hCapture, &hCapBuf) < 0) {
ERR("Failed to get capture buffer\n");
cleanup(THREAD_FAILURE);
}
if (resize) {
/* Resize buffer from 720P to a smaller resolution */
if (Resize_execute(hRsz, hCapBuf, hIntBuf) < 0) {
ERR("Failed to execute resize job\n");
cleanup(THREAD_FAILURE);
}
hInBuf = hIntBuf;
}
else {
hInBuf = hCapBuf;
}
/*
* Color convert the captured (and possibly resized)
* buffer from 422Psemi to 420Psemi.
*/
if (Ccv_execute(hCcv, hInBuf, hDstBuf) < 0) {
ERR("Failed to execute color conversion job\n");
cleanup(THREAD_FAILURE);
}
question: a) How do I access pixel info like luma and chroma YUV structure of the frame from the hDstBuf which is a pointer to Buffer_Handle ? any code snippets available ? (I take from the comment
that it is in the 420Psemi format.)
b) are there any tools available for viewing the frame in this format after I retrieve it ?
Thanks in advance,
