Hello, Kinbay, Could you please check this ticket? Thank you. Sangmin Choi. |
|

Hi Mr. Sangmin Choi, May I know the purpose for this question? Thank you! |
|
|
Hello, Kerwin, There is an issue that the screen ratio option didn't set correctly. So, I'm discussing with AML engineer. He asked me if HAL_VCOMPO_SetScaleRatioMode function is called before initialize of systemcontrol service or not. Thank you. Sangmin Choi. |

Hi Mr. Sangmin Choi, From your messages, you can see "SystemControlService" is printed before SetScaleRatioMode(). In fact, the flow looks like below HAL_VCOMPO_SetScaleRatioMode() { .. client=getSystemControlService(); .. LOGD("%s<%s> .. sourceIn %d\n", LOG_TAG, __FUNCTION__, sourceIn); client->setDisplayMode(); <-- Amlogic API to set Screen Ratio } Thank you! |

Hello, Kerwin, So, "System Control Service init" message will be printed every HAL_VCOMPO_SetScaleRatioMode function call? And, do you return error value if setDisplayMode return error? Thank you. Sangmin Choi. |

Hi Mr. Sangmin Choi, So, "System Control Service init" message will be printed every HAL_VCOMPO_SetScaleRatioMode function call? => yes, it is in getSystemControlService(); And, do you return error value if setDisplayMode return error? => I think you could check if there is any error in Amlogic's API first. It is open on BitBucket. Thank you! |

Hello, Kerwin, SystemControlService::setDisplayMode returns error. I just want to know HAL_VCOMPO_SetScaleRatioMode return the error which is from SystemControlService::setDisplayMode or not. Thank you. Sangmin Choi. 스크린샷 2024-04-03 오전 11.30.24.png (55,854 bytes) |

Hi Mr. Sangmin Choi, Current, 'HAL_VCOMPO_SetScaleRatioMode' doesn't check return value from SystemControlService::setDisplayMode. |
|
|
Hello, Kerwin, Ok, thank you. Also, VCOMPO_SetScaleRatioMode doesn't check return value from HAL_VCOMPO_SetScaleRatioMode. It's OK now, I will request it when it needs. Thank you. Sangmin Choi. |
