从FFPROBE生成的JSON文件中读取和提取特定信息的Python程序

import json

def extract_info(json_file):
    with open(json_file, 'r') as f:
        data = json.load(f)

    # 提取特定信息
    video_streams = []
    audio_streams = []

    for stream in data['streams']:
        if stream['codec_type'] == 'video':
            video_streams.append(stream)
        elif stream['codec_type'] == 'audio':
            audio_streams.append(stream)

    return video_streams, audio_streams

# 使用示例
json_file = 'path/to/ffprobe.json'
video_streams, audio_streams = extract_info(json_file)

# 打印提取的信息
print('Video Streams:')
for stream in video_streams:
    print('Codec: {}'.format(stream['codec_name']))
    print('Resolution: {}x{}'.format(stream['width'], stream['height']))
    print('Bitrate: {} kb/s'.format(stream['bit_rate'] / 1000))
    print('')

print('Audio Streams:')
for stream in audio_streams:
    print('Codec: {}'.format(stream['codec_name']))
    print('Sample Rate: {} Hz'.format(stream['sample_rate']))
    print('Bitrate: {} kb/s'.format(stream['bit_rate'] / 1000))
    print('')
