Hi @gavel94 , |
|
After I set “ frameProcessor.setVideoInputStreamCpu("input_video")”. I got the following log。 |

Hi @gavel94 , |

According to the document inheritance, above I already use all the code related to mediapipe. import android.graphics.Bitmap /**
*/ // private val mCameraWidth = 320 // mCameraHelper.setDefaultFrameFormat(UVCCameraHelper.FRAME_FORMAT_MJPEG) // if (abs(contourArea) > mMinContourArea) { // if (!mBaseBitmapFlag) { // var hvsMat = Mat() // Imgproc.cvtColor(mat, hvsMat, Imgproc.COLOR_YUV420p2GRAY) // Thread.sleep(100); } |

Here is my ARR packaging script。I don't know if this helps with the problem.Thank you very much for your help。 mediapipe_aar( |
|
How do I use this method？ Could you give me an expedited treatment? If this plan doesn't work, I can consider another one. Thank you very much. |

Hi @gavel94 , |
|
During this time, I tried various ways but couldn't achieve my needs.
During this time, I tried various ways but couldn't achieve my needs. For now, I prefer to use Mediapipe to solve the posture problem. I don't understand how to verify the type and content later. The bitmap is converted by OpencV and displayed on the screen as a normal preview. |
|
I think the error is indicating that the "stream_name" parameter to nativeMovePacketToInputStream() is bad. This might mean that the instance variable "FrameProcessor.videoInputStream" is not properly initialized through FrameProcessor.addVideoStreams(). |

问题是在使用MediaPipe的Java API时，无法正确加载GPU资源。解决方法是在AndroidManifest.xml文件中添加以下权限： 此外，还需要在build.gradle文件中添加以下依赖项： 最后，以下是完整的Java代码示例： import android.Manifest;

Hello @gavel94, You can continue to use those legacy solutions in your applications if you choose. Though, we would request you to check new MediaPipe solutions which can help you more easily build and customize ML solutions for your applications. These new solutions will provide a superset of capabilities available in the legacy solutions. Thank you |

This issue has been marked stale because it has no recent activity since 7 days. It will be closed if no further activity occurs. Thank you. |

I'm seeing the following crash after a call to (the very first frame after app launch) :
processor.onNewFrame(bitmap, System.currentTimeMillis());
Integrate pose detection according to documentation.
1，Initialize
‘’‘
try {
processor = FrameProcessor(activity,"pose_tracking_gpu.binarypb")
‘’‘
2, use
Get data in the USB camera callback。
Data is converted to Bitmap via OpencV。
‘’‘
val cacheBitmap = Bitmap.createBitmap(
bgMat.cols(),
bgMat.rows(),
Bitmap.Config.ARGB_8888
)
Utils.matToBitmap(bgMat, cacheBitmap)
processor?.onNewFrame(cacheBitmap,System.currentTimeMillis())
‘’’
3，result
The following logs are obtained after calling “processor?.onNewFrame(cacheBitmap,System.currentTimeMillis())”
