whisper生成字幕python代码实现

要在Python中生成字幕文件（通常是SRT格式），你可以使用以下代码示例：

import os
 
def generate_subtitles(video_path, output_path, start_time, end_time, text):
    if not video_path.endswith('.mp4'):
        raise ValueError("Video file must be an MP4 format.")
 
    basename = os.path.basename(video_path)
    video_name = os.path.splitext(basename)[0]
    output_sub_path = os.path.join(output_path, f"{video_name}.srt")
 
    start_time_str = start_time.strftime("%H:%M:%S,%f")
    end_time_str = end_time.strftime("%H:%M:%S,%f")
 
    with open(output_sub_path, 'w', encoding='utf-8') as subtitle_file:
        subtitle_file.write(f"1\n{start_time_str} --> {end_time_str}\n{text}\n")
 
# 使用方法：
# 视频文件路径
video_file = 'your_video.mp4'
# 字幕输出路径
output_directory = 'subtitles'
# 字幕开始时间
start_time = datetime.datetime(2023, 4, 1, 12, 0, 0)
# 字幕结束时间
end_time = datetime.datetime(2023, 4, 1, 12, 15, 0)
# 字幕文本
text = "这里是字幕内容"
 
generate_subtitles(video_file, output_directory, start_time, end_time, text)

确保你已经安装了datetime模块，这个模块用于处理时间。上述代码会在指定的输出目录中创建一个SRT格式的字幕文件。你需要根据你的具体需求修改video_file, output_directory, start_time, end_time, 和 text变量。
