2017-02-13 03:58:12 -0600 | commented answer | Loading video files using VideoCapture in Android Got it finally! My source video is input.mp4. First, I converted that to MJPEG |
2017-02-13 02:07:17 -0600 | commented answer | Loading video files using VideoCapture in Android @berak, I tried couple of videos both in AVI and MP4 format with respective extensions to no avail. I don't know how to put MPEG in AVI! I have tried this command |
2017-02-11 06:20:50 -0600 | commented answer | Loading video files using VideoCapture in Android seems ffmpeg can be used as a plugin to opencv! |
2017-02-11 00:42:01 -0600 | commented answer | Loading video files using VideoCapture in Android Thanks Berak for these pointer, I'll explore it more. In fact, end product is stitching/merging multiple streams from cameras connected to an Android tablet via OTG USB hub. I am novice in this area and that is why I have picked up working with couple of offline videos first. I hope my approach is correct? Great if you could share some links regrading opencv+ffmpeg on Android or anything related to my project! Thanks. |
2017-02-10 06:16:24 -0600 | asked a question | Loading video files using VideoCapture in Android Hi, My aim is to load two video files, grabbing the frames from each file and creating a single frame. I have understood I can use I have two AVI files stored at It always pronts "Could not open ..." message. I have tested the file paths using File.exists and it returns true. What am I missing here? I am using OpenCV 3.2.0 for Android and Android lollipop. My Android setup is done properly and I can view the camera in JavaCameraView. |
