Hello, based on the printed information, it appears that the issue is caused by the missing <mediaserver.h> header file. From the source code, it seems that this is due to the MEDIASERVER_ROCKFACE definition. This option is disabled by default in the CMakeLists.txt file. Please check if this option is needed; if not, you can remove the MEDIASERVER_ROCKFACE define.

Dear Crocodile

Thank you for your answer.

I have a question and an error and would like to request a response.

1. Can't use MEDIA SERVER ROCKFACE?

2. Build after removing MEDIASERVER_ROCKFACE. The error below occurred. Do you know why?

ipcweb-backend is an example provided by Rockchip and is included in the SDK. We've only tested its basic usage. This example is suitable for multiple platforms, but not all features are supported on every platform. We haven't tested it extensively and do not provide technical support for it. The configurable attributes currently supported by ipcweb-backend can be enabled or disabled in the .Boardconfig board support file. I have tested it on my end, and it can be configured normally after being enabled. However, I'm not sure what other configurations you've made, so I can't determine the cause of the compilation error.

Dear Crocodile

Is there a build app guide document? If you have any documentation regarding setup, please let me know.

thank you

Unfortunately, I don't have any documentation related to rkipc-backend. There is a Chinese user guide for the rkipc application, but it only contains a brief introduction regarding the backend part, and there is no corresponding English version.

Dear Crocodile.

How did you successfully build the sdk? I got a build link error. There seems to be no library. How did you install cgicc lib? Please confirm.

Many Thanks.

I re-pulled the SDK and compiled it. After enabling RK_APP_IPCWEB_BACKEND in the .BoardConfig.mk, the compilation completed without any issues. I'm unable to determine what changes you made, so I'm unable to provide assistance. Please ensure the SDK is complete, as the repository should include libcgicc.so by default.

Dear Crocodile

I solved it.

RK_APP_IPCWEB_BACKEND After change

I did a rebuild.

Problem solved.

thank you
