Descriptions :
FFmpeg is a set of open source libraries that allow you to record, convert digital audio and video recordings in different formats. It includes libavcodec, an audio and video encoding and decoding library, and libavformat, a multiplexing and demultiplexing library in a multimedia container. The name comes from the name of the expert group MPEG and FF, which means fast forwarding. FFmpeg is already integrated in the program and does not require the download of additional codecs. The conversion takes place directly on the device (Internet is not required) and the conversion speed depends on the processor speed of the device.
