帖子: RE: h264enc: ROI_FOREGROUND_TYPE

TI有没有使用 VENC_IH264_FOREGROUND_OBJECT的相关例子。我只是想知道参数怎么配置。我现在认为ROI参数配置如下，就能提高ROI区域的QP值。

params.roiParams.roiNumOfRegion = 1; // count;
for(winId=0; winId < params.roiParams.roiNumOfRegion; winId++)
{
params.roiParams.roiStartX[winId] = 50;
params.roiParams.roiStartY[winId] = 50;
params.roiParams.roiWidth[winId] = 100;
params.roiParams.roiHeight[winId] = 100;
params.roiParams.roiType[winId] = VENC_IH264_FOREGROUND_OBJECT;

/*Mask color is input throught roiPriority*/
params.roiParams.roiPriority[winId] = VENC_GENERATE_FILL_PATTERN( 0x10,0x10,0x10);
}

Venc_setDynamicParam(0, 0, &params, VENC_ROI);

不过这样设置后，出现了下面的错误:

[m3video] ENCLINK:ERROR in Enclink_h264EncodeFrameBatch.Status[-1] for IVAHD_1
[m3video] 12118:WARN

我实在不知道怎么办了。没其他资料可以查了，能想到的调试方案也用尽了，只好继续来向您请教了。
