器件型号：TDA2SX 工具与软件：
如何 使用 TI Vision SDK 3.04配置 h264SPS (序列参数集)帧的 VUI 信息。
平台： TDA2SX
SDK 版本： TI Vision SDK 3.04
H264编码器 HDVICP2版本： H264ENC_TI DEV.500.V.H264AVC E.IVAHD.02.01.09.01
根据 h264_Encoder_HDVICP2_UserGuide.pdf、 我 尝试修改了 enclink_h264_set_static_params 函数代码。
H264 SPS 帧中仍然没有 VUI 信息。
enclink_h264_set_static_params 的代码如下所示
static Int enclink_h264_set_static_params(IH264ENC_Params * staticParams,
EncLink_AlgCreateParams *
algCreateParams)
{
/* Initialize default values for static params */
*staticParams = H264ENC_TI_PARAMS;
/* Both width & height needs to be align with 2 bytes */
staticParams->videnc2Params.maxHeight =
VpsUtils_align(algCreateParams->maxHeight, 2);
staticParams->videnc2Params.maxWidth =
VpsUtils_align(algCreateParams->maxWidth, 16);

algCreateParams->maxInterFrameInterval;

algCreateParams->inputContentType;

algCreateParams->inputChromaFormat;

this will be ignored. */

}
else
{
staticParams->numTemporalLayer = algCreateParams->numTemporalLayer;
}

are generally able to play back such a stream. */
/* Needs to be enabled to IH264_SVC_EXTENSION_FLAG_ENABLE for the
svc extension headers to be present in the stream*/
/*!!! Note: This flag needs to be enabled for the temporalId to be parsed
out from the stream.*/

algCreateParams->enableSVCExtensionFlag;

codec type*/
