dvrrdk4多slice编码

哪位做过dvrrdk4多slice编码，除了修改outputdatamode、slicemode、sliceuintsize之外还需要修改哪些项呢？谢谢！

Ternence_Hsu：

你好；

需要在mcfw中enclink_h264.c 中添加：

 

dynamicParams->sliceCodingParams.sliceCodingPreset = IH264_SLICECODING_USERDEFINED;dynamicParams->sliceCodingParams.sliceMode = IH264_SLICEMODE_BYTES;dynamicParams->sliceCodingParams.streamFormat = IH264_BYTE_STREAM;dynamicParams->sliceCodingParams.sliceUnitSize = 1200;

注：按字节划分slice只支持baseline模式；

建议查看手册：

DVRRDK_04.00.00.03/ti_tools/codecs/REL.500.V.H264AVC.E.IVAHD.02.00.04.01/500.V.H264AVC.E.IVAHD.02.00/IVAHD_001/Docs/H264_Encoder_HDVICP2_UserGuide.pdf

我在enclink_h264_set_static_params和enclink_h264_set_dynamic_params中修改了sliceCodingParams,熵编码是CAVLC编码,但是编出来的还是单slice的码流,还有其他的参数要修改吗?谢谢!

你好；

你只需要在

static Int enclink_h264_set_dynamic_params(IH264ENC_DynamicParams *dynamicParams,EncLink_AlgDynamicParams *algDynamicParams)

这个函数的最后加上我上面的4行代码就可以了， 用baseline编码，其他什么都不需要修改

只修改enclink_h264_set_dynamic_params也是不行的,我在调用enclink_h264_set_dynamic_params之后调用enclink_h264_print_dynamic_params看到参数是对的,请问有什么调试方法验证吗?怎么确认参数已经正确的设置到编码器的内部？谢谢!

从你打印

[m3video] sliceCodingParams -> sliceMode: 2
[m3video] sliceCodingParams -> sliceUnitSize: 1200

可以看出，配置是没有问题的；

当时刚才看你的码流，确实还是单个slice
