![]() ![]() Remarksįor lossy, compression_level is a quality/speed trade off. Syntax -compression_level integer Arguments integerValue ranges vary between encoders. ![]() To specify the level of compression required for the output with respect to the input. But for general purpose usage, image compression can be done by entering the input and output directly to FFmpeg and FFmpeg will automatically select the right decoder and encoder with the corresponding default value to process and optimize the input into the output.įfmpeg -i input output Switch: -compression_level The switches used for image compression are -compression_level, -q:v etc. The optimization of image compression in FFmpeg can be controlled by specifying the corresponding switches accordingly. PNG format is an example of lossless compression, JPEG/JPG format is an example of lossy compression. Every file format has its own compression method. Lossy image compression has a loss in quality but usually smaller file sizes. Lossless image compression has no loss in quality but usually bigger file sizes. ![]() The two types of methods used to compress a image are lossless and lossy compressions. Each image format uses different kind of algorithm to pack the picture data in one single file.įFmmpeg image compression is the process used to further optimize the balance between image quality and file size according to the specifed requirement. ![]() Image to image manipulation is one kind of simple functions available in FFmpegĭigital picture data can be stored in a image file of different format. The available FFmgeg functios only depend on the command line instruction. FFmpeg is a command line tool with a set of libraries in many dfferent formats for manipulating or prcessing multimedia data through encoding and decoding. ![]()
