Hi,
First,I'm working with the platform evmDM6437. I have used the project "video_preview" provided by the software "dvsdk_1_11_00_00", this project has worked correctly with the evmDM6437 and I have displayed the video frames with TV. Now , I'm working with a small board based on the dm6437 processor, I have used the same project "video_preview" with a small modifications to make it convenient to my needs. But, I have found a major issue in the function "FVID_allocBuffer". In fact, by the execution of this function my program would be blocked and I don't know what's the reason of this.
Beginning of "video_preview" program
--------------------------------
--------------------------------
/* allocate some frame buffers */
if (status == 0) {
for (i=0; i<FRAME_BUFF_CNT && status == 0; i++) {
result = FVID_allocBuffer(hGioVpfeCcdc, &frameBuffTable[i]);--------------------------------------------------> My program is blocked here.
status = (result == IOM_COMPLETED && frameBuffTable[i] != NULL ? 0 : -1);
}
}
------------------------------------
------------------------------------
End of "video_preview" program
