Transsizing refers to changing the picture size of video, and is useful if the output resolution differs from the resolution of the media.ĭepending on the requirements one can choose remuxing or transcoding. Transrating is the process by which video files and audio files are converted to a reduced bit rate while still maintaining the original media format. Remuxing is a lossless process that is used to change the container format of a given file(e.g. Integrating FFmpeg with Android applicationįor one of the projects there was a requirement to use FFmpeg for video processing.Being new to using FFmpeg I came across remuxing, transcoding, transrating and the transsizing process which are required to process videos.
