Usage


import "github.com/godcong/goav"

func main() {

	filename := "sample.mp4"

	// Register all formats and codecs
	goav.AVRegisterAll()

	ctx := goav.AVFormatAllocContext()

	// Open video file
	if AVFormatOpenInput(&ctx, filename, nil, nil) != 0 {
		log.Println("Error: Couldn't open file.")
		return
	}

	// Retrieve stream information
	if ctx.AVFormatFindStreamInfo(nil) < 0 {
		log.Println("Error: Couldn't find stream information.")

		// Close input file and free context
		ctx.AVFormatCloseInput()
		return
	}

	//...

}

Overview

Package goav contains the codecs (decoders and encoders) provided by the libavcodec library Provides some generic global options, which can be set on all the encoders and decoders.

Package goav deals with the input and output devices provided by the libavdevice library The libavdevice library provides the same interface as libavformat. Namely, an input device is considered like a demuxer, and an output device like a muxer, and the interface and generic device options are the same provided by libavformat

Package goav contains methods that deal with ffmpeg filters filters in the same linear chain are separated by commas, and distinct linear chains of filters are separated by semicolons. FFmpeg is enabled through the "C" libavfilter library

Package goav provides some generic global options, which can be set on all the muxers and demuxers. In addition each muxer or demuxer may support so-called private options, which are specific for that component. Supported formats (muxers and demuxers) provided by the libavformat library

Package goav provides a high-level interface to the libswresample library audio resampling utilities The process of changing the sampling rate of a discrete signal to obtain a new discrete representation of the underlying continuous signal.

Package goav performs highly optimized image scaling and colorspace and pixel format conversion operations. Rescaling: is the process of changing the video size. Several rescaling options and algorithms are available. Pixel format conversion: is the process of converting the image format and colorspace of the image.
