video-capture

I'm new to JavaCV and I have difficult time finding good tutorials about different issues on the topics that I'm interested in. I've succeed to implement some sort of real time video streaming from my webcam but the problem is that I use this code snippet which I found on the net : @Override public void run() { FrameGrabber grabber = new VideoInputFrameGrabber(0); // 1 for next // camera int i = 0; try { grabber.start(); IplImage img; while (true) { img = grabber.grab(); if (img != null) { cvFlip(img, img, 1);// l-r = 90_degrees_steps_anti_clockwise cvSaveImage((i++) + "-aa.jpg", img); // show

I am porting my Direct Show camera based SDK to MFT. In my old code I have KSProxy interface like IksTopolgy,IKsControl and IKsProperty . IksTopolgy,IKsControl is used to enumerate the property set and IKsProperty to get/set the property value. Now I was trying to same in new code.I am able to enumerate the property i.e following code is supported in MFT. CComPtr<IKsTopologyInfo> ksTopology = NULL; hRet = m_pMediaSource->QueryInterface(&ksTopology); But IKsProperty interface which is used to get/set the property value is not working returning E_NOINTERFACE. hRet = m_pMediaSource-

I have a Canon 7D digital camera and I'd like to have an ability to control video recording from PC. I've downloaded Canon SDK 2.8, read all the document it contains but still cant figure out how to start or stop video recording on the camera. Is there any possibility to control video recording via Canon SDK? Thanks. the latest canon camera sdk document contains an answer: 6.4.3 Begin/End movie shooting You can begin/end movie shooting with the following operations. EdsUInt32 record_start = 4; // Begin movie shooting err = EdsSetPropertyData(cameraRef, kEdsPropID_Record, 0, sizeof(record_start

Good day! I'm learning how to record video with MediaRecorder but recorded video is corrupted when I play it. See this screenshot: http://www.4shared.com/photo/QtmJCHRi/corrupted-video.html . Picture marked with red rectangle in the left upper corner is what camera can see. But it is so small, it's repeating and there is many green areas. Please advise what am I doing wrong. HW is Samsung Galaxy S2 (GT-I9100, Android 2.3.5). I tried to follow this tutorial: http://developer.android.com/guide/topics/media/camera.html#saving-media Thank you in advance!

I'm creating a Windows video capture application and am using DirectShow for capture. As each frame comes in, I want to grab it as a raw RGB bitmap into a buffer, at which point my code will do whatever processing I need. I've been searching for samples similar to what I want to do, and everywhere I look online, people recommend using either the IMediaDet and/or the ISampleGrabber interface to do frame-by-frame capture. Unfortunately, both are deprecated and aren't even in the newest version of the Windows SDK. What is the best (modern) way to do frame-by-frame capture in DirectShow? If there

I would like to take video from a webcam, render some text on the frames and do some motion tracking and pass it on to a virtual webcam so it can be streamed easily. I found some answers on stackoverflow suggesting that I should use DirectShow. According to information in DirectShow documentation , the DirectShow SDK is part of Windows SDK. So I installed the latest Windows SDK but it seems that it doesn't include DirectShow because there are no DirectShow samples under C:\Program Files (x86)\Microsoft SDKs\Windows . (The stackoverflow answers are also pretty old - dated around 2010) Can you
