Video-Cap | Video Captioning : ICCV '15 paper implementation | Machine Learning library

I am trying to read the stream from HDMI-USB video-capture card using opencv. But OpenCV doesn't seem to support that functionality. I used opencv to read RTSP streams and webcams. Can anyone suggest a way here. Currently I am accessing the stream using OBS Studio software. Is there any other module in python that I can use. Thanks in advance.

There's a similar question here. But that approach doesn't work for me.

I´m trying to upload a video using Ionic / Capacitor / React.

For this, I´m using the cordova-video-capture-plus plugin.

I´m getting stuck when I try to readAsArrayBuffer. For some reason it always comes back empty, below my code:

I'm working on a embedded linux system (yocto based) and I'm trying to simply get a list of the camera USB video devices (webcams) numbers with the related connected usb port from a C program.

I'm able to get the devices list with vendor ID and connected port doing this:

I would like to use a custom video source to live stream video via WebRTC Android implementation. If I understand correctly, existing implementation only supports front and back facing cameras on Android phones. The following classes are relevant in this scenario:

• Camera1Enumerator.java
• VideoCapturer.java
• PeerConnectionFactory
• VideoSource.java
• VideoTrack.java

Currently for using front facing camera on Android phone I'm doing the following steps:

I have to create a virtual cam in c# asp.net which should be accessible in skype and adobe live flash encoder. In c#, I have found only this link describes how can achieve this. But when trying with the source code they provide, I'm getting two errors ,

I have given full control permission for HKEY-CLASSES-ROOT.

And when I'm trying with thier binary code, command prompt says

RegAsm : error RA0000 : Unable to locate input assembly 'VirtualCam.dll' or one of its dependencies.

Can you help me to solve this issue? My system is 64 bit operating system.

I am making an app that records video. Up until now, I have been able to successfully record video and audio using AVCaptureMovieFileOutput, however, I now have a need to edit the video frames in real time to overlay some data onto the video. I began the switch to AVAssetWriter.

After the switch, I am able to record video (with my overlays) just fine using AVCaptureVideoDataOutput, however, AVCaptureAudioDataOutput never calls the delegate method so my audio doesn't record.

This is how I set up my AVCaptureSession:

I am working on an image-processing project where I want pictures from 3 cameras to get the latest frame when a button is pressed and for that, I have used multiprocessing.process and multiprocessing.queue as shown in the code below. The required task is achieved but there are 2 problems right now:

1.cpu-100% in task manager(which slows down the program)

2.there is a workaround for cam.set(cv2.CAP_PROP_BUFFERSIZE, 0) in the code which is the main cause for 50% of cpu usage

actually I want a fast way to get frames so I have also tried multiprocessing.pipe instead of the queue but since it does not get the latest frame when button pressed for the second time so I had to use queu communication method. Any help regarding code would be much appreciated

I want some help in creating thumbnail of a video being recorded from my android phone and I got this code from this Link, and I modified this part of the code to generate the thumbnail but somehow the thumbnail is not being generated, so any help will be appreciated.
