To convert a YouTube video to a different format using ffmpeg, you can use the following command in the terminal: ffmpeg -i input video URL -c:v video codec -c:a audio codec output file name.output format Replace input video URL with the URL of the YouTube video, video codec with the desired video codec, audio codec with the desired audio codec, output file name with the name you want for the output file, and output format with the desired format (e.g., mp4, avi, etc.). Make sure you have ffmpeg installed on your system before running the command.

Codec is a piece of software that translates video and audio data into and from proprietary formats of which MKV is one. It is the codec that enables the computer to interpret data from the proprietary source format.
No, MP4 is not a codec. MP4 is a file format used for storing digital multimedia content, while a codec is a software or hardware tool used to compress or decompress audio or video data.
Yes,To play a flv file format, download and install a codec pack (such as klite codec pack, etc) which will enable to support flv format file playback in Windows Media Player.But it is recommended to install the codec pack after the installation of Windows Media Player.

There are many software media players available, some with more advanced features than others. One thing that all software media players have in common, however, is their need for a media codec in order to play different types of files. A codec is an independent software library that contains all of the information necessary to decode a particular media file format. If a software media player is having difficulty opening or playing a file, then the most likely cause is a missing or outdated codec.
you're probably missing the DivX codec or the video file is copy protected
An mp4 is a format for a movie file. It is technically an Apple format that most PC media players can't open without the appropriate codec installed.
