Dayanzai (www.dayanzai. me) learned that FFmpeg 7.0 has been updated and released. FFmpeg is a leading multimedia framework, capable of decoding, encoding, transcoding, mux，demux， Streaming, filtering and playing almost all content created by humans and machines. It supports the most obscure ancient formats up to the forefront. Whether they are designed by a standards committee, community or company. It also has a high degree of portability: FFmpeg can cross Linux under various construction environments, machine architectures and configurations, Mac OS X, Microsoft Windows, BSD, Solaris, etc. compile, run, and pass our test infrastructure FATE.

ffprobe

Ffprobe is a tool for viewing media file header information. Common commands are:

 one
 two
 three
 four
 five
 six
 ffprobe INPUT
 ffprobe - show_format INPUT
 ffprobe - show_streams INPUT
 ffprobe - show_frames INPUT
 ffprobe - show_packets INPUT

 ...

Show_format is used to view file format, duration, code rate and other information, which is relatively simple;

Show_streams is used to view the information of video stream and audio stream, including encoder, frame rate, sampling rate, width and height, pixel format, sampling format, code rate, duration, total frame rate, etc. It is more detailed and is the most commonly used function;

Show_frames and show_packets are used to view the information of each frame (before decoding/after decoding), and can be used with select_streams;

ffplay

Ffplay is a tool for playing media files. Common commands are:

 one
 two
 three
 four
 five
 ffplay INPUT - loop ten  //Loop 10 times
 ffplay INPUT - ast one  //Play the first audio stream in the video
 ffplay INPUT - vst one  //Play the first video stream in the video
 ffplay INPUT - x WIDTH - y HEIGHT //Specify width and height to play

 ...

Play original audio/video data:

 one
 two
 ffplay INPUT . pcm - f s16le - channels two  - ar forty-four thousand and one hundred
 ffplay - f rawvideo - pixel_format yuv420p - s four hundred and eighty * four hundred and eighty INPUT . yuv ( Or rgb )

Specify how to synchronize audio and video during playback:

 one
 ffplay INPUT - sync audio ( Or video ext )  //Use audio (or video, or external clock) as the reference for audio and video synchronization

ffmpeg

Ffmpeg is a powerful media file conversion tool, which is commonly used for transcoding. There are many optional commands. Encoder, video duration, frame rate, resolution, pixel format, sampling format, code rate, clipping options, number of sound channels, etc. can be freely selected:

 one
 ffmpeg - i input . mp4 output . avi

 one
 ffmpeg - i INPUT - codec : v h264 - codec : a aac - s 644x360 OUTPUT

Due to the complexity of FFmpeg and the lack of friendly graphical user interface, it can only solve a small number of users. Although in fact, it is the core of the audio/video converter, FFmpeg is not the software most users are accustomed to using.

First, since its establishment in 2000, FFmpeg has been constantly updated to meet the growing expectations of the community, especially advanced users. For those who may have heard of it, FFmpeg is really behind a variety of application software that only serves as the GUI of the program, making it as easy as possible to use this very interesting command prompt utility.

As long as you are not interested in software that only depends on its interface, and have little dependence on its function, FFmpeg will indeed threaten more popular applications, thus limiting your choice from predefined configuration files. On the other hand, many well-known programs use FFmpeg, and this special category only includes MPlayer, VLC or HandBrake.

FFmpeg is really tailored for command prompt control freaks, who just need full authorization of the whole process, which may take a lot of time to modify settings and create a considerable number of configuration files to meet various situations. Among the most well-known container formats supported by FFmpeg, you can consider using ASF, AVI, FLV, MKV, MPEG or OGG (OGV).

FFmpeg is not an ideal tool for every user, but it can be considered as the only tool for many lovers to dominate them. Although their supporters may not be able to compete with other competitors, generally speaking, these members are more experienced and can really talk about and spend hours solving media conversion problems that other people do not even know about.
