Video display in Imgui using C++ and ESCAPI

To create an application that can view the webcam using ImGUI, C++, and ESCAPI, you can follow these steps:




  1. Install the required libraries and tools: You will need to have the ImGUI, C++, and DirectX11 libraries and tools installed on your system in order to build the application. You may also need to install additional libraries or tools that are required to access the webcam and capture video frames, such as the Microsoft Media Foundation library or the OpenCV library.

  2. Set up the ImGUI interface: Use the ImGUI library to set up the user interface for the application. This will typically involve creating the layout for the application's window, as well as any necessary buttons, sliders, or other controls that will be used to interact with the webcam.

  3. Initialize the ESCAPI context: Use the ESCAPI library to create a context that will be used to grabbing the webcam video frames. This will typically involve setting up a creating a render target, and initializing any necessary resources.

  4. Alternatives of ESCAPI, other webcam capture: Use a library or tool such as the Microsoft Media Foundation library or the OpenCV library to set up the webcam capture. This will typically involve opening the webcam device, setting the desired capture resolution and frame rate, and starting the capture.

  5. Render the webcam video frames: In the application's main loop, use the webcam capture library to retrieve the latest video frame from the webcam and library to render the video frame to the render target. Use the ImGUI library to draw the render target to the application window.

  6. Clean up resources: When the application is closed, be sure to release any resources that were allocated during the application's execution, such as the graphics context, the webcam capture, and any other resources that were created.

Image overlay on video using c++ and ffmpeg API

This project is NOT a command line, It is a tool written in C++ that uses the FFmpeg library to overlay an image on top of a video. The tool takes as input a video file, an image file, and the output file name, and overlays the image on top of the video at a specified location and for a specified duration. watch the demo on youtube The tool uses the FFmpeg library to decode the video and image, and to encode the output video with the overlay. It also allows the user to specify the x and y coordinates of the top-left corner of the image, as well as the width and height of the image, in pixels. The tool can be used to add a logo or watermark to a video, or to add other types of visual overlays. To use the tool, the user needs to have FFmpeg installed on their system and available in the system's PATH. The user can then compile the C++ source code and run the resulting executable from the command line, specifying the necessary arguments. source code: https://github.com/abdullahfarwees

A Comprehensive Guide to Encoding H.264 Video with MP4 Container Using Controllable Frame Rate and Bitrate in libavcodec

Introduction If you're working with multimedia applications or video production, you may often find yourself in a situation where you need to encode video with specific settings like H.264 codec, MP4 container, and controllable frame rate and bitrate. libavcodec, a vital component of the FFmpeg multimedia framework, can help you achieve this. In this guide, we will walk you through the steps to encode video with these requirements and introduce you to the concept of presets to control encoding quality. Encoding with libavcodec libavcodec is a powerful library for encoding and decoding audio and video streams. To encode video with H.264 codec and MP4 container while controlling the frame rate and bitrate, you can use the following.   Set Encoding Options: To control the encoding quality, you can set the encoding options using the AVDictionary structure. In this case, we'll focus on the 'preset' option, which defines the encoding speed and quality.  The available presets
