使用方法

Python API

from skills.ffmpeg_processor import FFmpegProcessor

ff = FFmpegProcessor()

# 检查 FFmpeg 是否可用
print(f"FFmpeg 可用: {ff.check_ffmpeg()}")

# 格式转换
ff.to_mp4('input.avi', 'output.mp4')
ff.to_mp3('input.mp4', 'output.mp3')

# 获取媒体信息
info = ff.get_video_info('video.mp4')
print(f"分辨率: {info['video_resolution']}")
print(f"时长: {info['duration']}秒")

# 裁剪视频
ff.trim_video('input.mp4', 'output.mp4', 
              start_time='00:00:10', 
              duration='00:00:30')

# 调整尺寸
ff.resize_video('input.mp4', 'output.mp4', 1280, 720)

# 视频转 GIF
ff.video_to_gif('input.mp4', 'output.gif', fps=15)

# 添加水印
ff.add_watermark('input.mp4', 'output.mp4', 
                'logo.png', position='br')

# 提取帧
frames = ff.extract_all_frames('video.mp4', 'frames/', fps=1)
