TMS320DM8168: 请教: 关于DM8168视频解码的相关问题!

Part Number: TMS320DM8168

各位大神:

        请教一下DVRRDK4.0中,在使用decoder进行解码的时候,多个channel是否可以设置不同的分辨率?(注:decode之后还会用到scaler进行缩放处理)

比如如下设置

Void Vdec_params_init(VDEC_PARAMS_S * pContext)
{
UInt16 i;

memset(pContext, 0, sizeof(VDEC_PARAMS_S));

pContext->forceUseDecChannelParams = FALSE;

i = 0;

pContext->decChannelParams[i].dynamicParam.frameRate = 30;
pContext->decChannelParams[i].dynamicParam.targetBitRate = 2 * 1000 * 1000;
pContext->decChannelParams[i].maxVideoWidth = 1920;
pContext->decChannelParams[i].maxVideoHeight = 1080;
pContext->decChannelParams[i].tilerEnable = FALSE;
pContext->decChannelParams[i].fieldPicture = FALSE;

i = 1;

pContext->decChannelParams[i].dynamicParam.frameRate = 30;
pContext->decChannelParams[i].dynamicParam.targetBitRate = 2 * 1000 * 1000;
pContext->decChannelParams[i].maxVideoWidth = 1280;
pContext->decChannelParams[i].maxVideoHeight = 720;
pContext->decChannelParams[i].tilerEnable = FALSE;
pContext->decChannelParams[i].fieldPicture = FALSE;

i = 2;

pContext->decChannelParams[i].dynamicParam.frameRate = 30;
pContext->decChannelParams[i].dynamicParam.targetBitRate = 2 * 1000 * 1000;
pContext->decChannelParams[i].maxVideoWidth = 720;
pContext->decChannelParams[i].maxVideoHeight = 576;
pContext->decChannelParams[i].tilerEnable = FALSE;
pContext->decChannelParams[i].fieldPicture = FALSE;


}
