This library relies on FFmpeg, and FFProbe which must be downloaded before usage and added to the system path. All frames are encoded and decoded in 8-bit RGB format. Installation go get github.com/AlexEidt/Vidio Video The Video struct stores data about a video file you give it. The code below shows an example of sequentially reading the frames of the given video. FileName() string Width() int Height() int Depth() int Bitrate() int Frames() int Duration() float64 FPS() float64 Codec() string AudioCodec() string FrameBuffer() []byte video := vidio.NewVideo("input.mp4") for video.Read() { // "frame" stores the video frame as a flattened RGB image in row-major order frame := video.FrameBuffer() // stored as: RGBRGBRGBRGB... // Video processing here... } Camera The Camera can read from any cameras on the device running Vidio. It takes in the stream index. On most machines the webcam device has index 0. Note that audio retrieval from the microphone is not yet supported. Name() string Width() int Height() int Depth() int FPS() float64 Codec() string FrameBuffer() []byte camera := vidio.NewCamera(0) // Get Webcam defer camera.Close() // Stream the webcam for camera.Read() { frame := camera.FrameBuffer() // Video processing here... } VideoWriter The VideoWriter is used to write frames to a video file. The only required parameters are the output file name, the width and height of the frames being written, and an Options struct. This contains all the desired properties of the new video you want to create. FileName() string Width() int Height() int Bitrate() int Loop() int Delay() int Macro() int FPS() float64 Quality() float64 Codec() string AudioCodec() string type Options struct { Bitrate int // Bitrate Loop int // For GIFs only. -1=no loop, 0=loop forever, >0=loop n times Delay int // Delay for Final Frame of GIFs. Default -1 (Use same delay as previous frame) Macro int // macro size for determining how to resize frames for codecs. Default 16 FPS float64 // Frames per second. Default 25 Quality float64 // If bitrate not given, use quality instead. Must be between 0 and 1. 0:best, 1:worst Codec string // Codec for video. Default libx264 Audio string // File path for audio for the video. If no audio, audio="". AudioCodec string // Codec for audio. Default aac } w, h, c := 1920, 1080, 3 options := vidio.Options{} // Will fill in defaults if empty writer := vidio.NewVideoWriter("output.mp4", w, h, &options) defer writer.Close() frame := make([]byte, w*h*c) // Create Frame as RGB Image and modify writer.Write(frame) // Write Frame to video Images Vidio provides some convenience functions for reading and writing to images using an array of bytes. Currently, only png and jpeg formats are supported. // Read png image w, h, img := vidio.Read("input.png") // w - width of image // h - height of image // img - byte array in RGB format. RGBRGBRGBRGB... vidio.Write("output.jpg", w, h, img) Examples Copy input.mp4 to output.mp4. Copy the audio from input.mp4 to output.mp4 as well. video := vidio.NewVideo("input.mp4") options := vidio.Options{ FPS: video.FPS(), Bitrate: video.Bitrate(), Audio: "input.mp4", } writer := vidio.NewVideoWriter("output.mp4", video.Width(), video.Height(), &options) defer writer.Close() for video.Read() { writer.Write(video.FrameBuffer()) } Grayscale 1000 frames of webcam stream and store in output.mp4. webcam := vidio.NewCamera(0) defer webcam.Close() options := vidio.Options{FPS: webcam.FPS()} writer := vidio.NewVideoWriter("output.mp4", webcam.Width(), webcam.Height(), &options) defer writer.Close() count := 0 for webcam.Read() { frame := webcam.FrameBuffer() for i := 0; i < len(frame); i += 3 { rgb := frame[i : i+3] r, g, b := int(rgb[0]), int(rgb[1]), int(rgb[2]) gray := uint8((3*r + 4*g + b) / 8) frame[i] = gray frame[i+1] = gray frame[i+2] = gray } writer.Write(frame) count++ if count > 1000 { break } } Create a gif from a series of png files enumerated from 1 to 10 that loops continuously with a final frame delay of 1000 centiseconds. w, h, _ := vidio.Read("1.png") // Get frame dimensions from first image options := vidio.Options{FPS: 1, Loop: 0, Delay: 1000} gif := vidio.NewVideoWriter("output.gif", w, h, &options) defer gif.Close() for i := 1; i <= 10; i++ { _, _, img := vidio.Read(strconv.Itoa(i)+".png") gif.Write(img) } Acknowledgements * Special thanks to Zulko and his blog post about using FFmpeg to process video. * The ImageIO-FFMPEG project on GitHub.
