What is FFprobe?
FFprobe is a command-line tool that comes with the FFmpeg multimedia framework. It analyzes multimedia streams and metadata, including video and audio codecs, bitrates, frame rates, and resolutions. FFprobe is a powerful tool that can provide detailed information about video and audio files and is widely used in video production and post-production.
How does FFprobe Work?
FFprobe analyzes the media files and provides a comprehensive report that includes detailed information about the media streams. It can identify the video and audio codecs used in the file, the file's duration, the bitrates of the audio and video streams, and other relevant details. FFprobe can also be used to generate reports in various formats, such as XML, JSON, and CSV.
Examples of FFprobe
Here are some examples of how FFprobe can be used:
To check the codec information of a video file:
ffprobe -i input.mp4 -show_streams
To generate a JSON report of a video file:
ffprobe -i input.mp4 -print_format json -show_streams
To extract information about a specific stream:
ffprobe -i input.mp4 -select_streams v:0 -show_entries stream=width,height
Elements of FFprobe
- Media Stream Information: FFprobe can analyze media files and provide detailed information about the media streams, including video and audio codecs, bitrates, frame rates, and resolutions.
- Format Information: FFprobe can also provide information about the container format used in the media file, such as MPEG-4, AVI, or MKV.
- Metadata Information: FFprobe can extract metadata information from media files, such as the title, author, and copyright information.
