Basic Commands for FFmpeg Usage

Here are some commonly used FFmpeg commands:

1. Convert Video Format

Convert a video file from one format to another:

ffmpeg -i input.mp4 output.avi

2. Extract Audio from Video

Extract the audio and save it as an MP3 file:

ffmpeg -i input.mp4 -q:a 0 -map a output.mp3

3. Resize Video

Change the resolution of a video:

ffmpeg -i input.mp4 -vf scale=1280:720 output.mp4

4. Trim a Video

Cut a segment from a video (e.g., from 10 to 30 seconds):

ffmpeg -i input.mp4 -ss 00:00:10 -to 00:00:30 -c copy output.mp4

5. Merge Videos

Combine multiple video files:

Create a text file listing the videos:
```
file 'video1.mp4'
file 'video2.mp4'
```

Run:

ffmpeg -f concat -safe 0 -i filelist.txt -c copy output.mp4

6. Add Watermark to Video

Overlay a watermark image onto a video:

ffmpeg -i input.mp4 -i watermark.png -filter_complex "overlay=10:10" output.mp4

7. Adjust Video Speed

Speed up video:

ffmpeg -i input.mp4 -vf "setpts=0.5*PTS" output.mp4

Slow down video:

ffmpeg -i input.mp4 -vf "setpts=2.0*PTS" output.mp4

Advanced Features

1. Using Data from Data Layer

FFmpeg can work with metadata, such as timestamps and bitrates. For example, you can extract or modify file metadata:

2. Encoding and Compression

Compress video file size:
```
ffmpeg -i input.mp4 -vcodec libx265 -crf 28 output.mp4
