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！

    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；

    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!

    你参数设置对了，你能发一小段码流，让我分析一下吗？

    你好；

    从你打印

    [m3video] sliceCodingParams -> sliceCodingPreset  : 1
[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

    会不会你还有其他地方的改动导致的呢 ？

    我们的版本不一样，我的是DVRRDK04.01.00.02，编码器是H264ENC_TI DEV.500.V.H264AVC.E.IVAHD.02.00.06.00，附件是代码，是这个编码器不支持吗？还是参数设置的问题？谢谢！

    你好；

    确实h264编码器的版本升级了2个版本；

    刚才看了一下版本更新注释H264_Encoder_HDVICP2_ReleaseNotes.pdf；

    里面的对多slice编码的功能并没有影响的；

    请问你使用的是什么版本？调用enc link的代码能给我看一下吗？谢谢！

    你能在enclink_h264_set_dynamic_params之后，调用enclink_h264_print_dynamic_params，抓一下打印，给我看一下吗？能给我你的开发环境的安装包吗？谢谢！

    你好；

    这个是刚才上面参数打印时候编码多slice的码率，附件下载

    你好；

    关于RDK的源码包，最好是通过TI的技术支持获取，需要签NDA协议

    非常感谢你的帮助。问题总算解决了，要把encodepreset设置userdefine。谢谢！
