How to determine video codec of a file with ffmpeg?

To extract the video codec information – since ffmpeg sends information to stderr – pipe and grep it: To reduce the output even further, introduce sed: FFmpeg gives the codec too. Pull the Stream #0.0: Video line and you can see the codec. (Be aware that it could technically have a different stream number, like 0.1.)

To reduce the output even further, introduce sed: FFmpeg gives the codec too. Pull the Stream #0.0: Video line and you can see the codec. (Be aware that it could technically have a different stream number, like 0.1.) The below output uses the MS Video-1.

In addition each codec may support so-called private options, which are specific for a given codec. Sometimes, a global option may only affect a specific kind of codec, and may be nonsensical or ignored by another, so you need to be aware of the meaning of the specified options. Also some options are meant only for decoding or encoding.

FFmpeg is a command-line tool that uses commands to convert audio or video formats. For example: To extract sound from a video and save it as MP3, you can use command line: $ ffmpeg -i video1.avi -vn -ar 44100 -ac 2 -ab 192 -f mp3 audio3.mp3 It can also capture and encode in real-time from various sources such as a TV capture card.

features C# video library FFMpeg .NET wrapper: convert (encode,decode) almost all known video and audio formats (mp4,mp3,h264,wmv,wav,avi,flv,mov,mkv,webm,ogg and many others) no memory leaks: ffmpeg is executed in separate process all ffmpeg command-line options are supported

Stream show video stream information. A video file like mkv, mp4 may have more than one .stream for different purposes. In this example, we have only one stream with index 0:0 . There is information about the video stream like a video format resolution frame per second.

But FFMPEG is very easy to use. To export audio from a media file you just have to specify an output file with .mp3 or .aac as extension – e.g.: Unfortunately FFMPEG uses a bit-rate of 128kbps by default and in most cases will convert the audio instead of just extracting it which will take much longer.
