Hi,
I wish to perform rotation on real time video. I explored 'encodedecode' demo and found out 'display.c' could be my starting point. I explored 'ti/sdo/dmai/display.h' too for Display_Attrs_DM6446_DM355_VID_DEFAULT. I went deeper in the function Display_create() in the linux directory. dvsdk_2_00_00_22/dmai_1_20_00_06/packages/ti/sdo/dmai/linux and found out there are three 'c' files of my interest 'display.c' ,Display_fbdev.c', 'Display_v4l2.c' in order to tweak the function to accept 'rotation' attribute.
Void *displayThrFxn(Void *arg)
{
DisplayEnv *envp = (DisplayEnv *) arg;
Display_Attrs dAttrs = Display_Attrs_DM6446_DM355_VID_DEFAULT;
Framecopy_Attrs fcAttrs = Framecopy_Attrs_DEFAULT;
Display_Handle hDisplay = NULL;
Framecopy_Handle hFc = NULL;
Void *status = THREAD_SUCCESS;
Uns frameCnt = 0;
Int32 clipWidth = 0;
Int32 clipHeight = 0;
Int32 srcWidth = 0;
Int32 srcHeight = 0;
Int32 dstWidth = 0;
Int32 dstHeight = 0;
Int32 dstX = 0;
Int32 dstY = 0;
Buffer_Handle hSrcBuf, hDstBuf;
BufferGfx_Dimensions srcDim, dstDim;
Int fifoRet;
/* Create the display device instance */
dAttrs.numBufs = NUM_DISPLAY_BUFS;
dAttrs.videoStd = envp->videoStd;
dAttrs.videoOutput = envp->displayOutput;
// added by Virgoptrex
dAttrs.rotation = 90; // This looks like only application on OMAP - didn't give me any compilation error but wouldn't do anything either.
hDisplay = Display_create(NULL, &dAttrs);
Anyone tried this?
