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