一句话生成视频(python)

最近想运营个抖音号, 但是制作视频是个很麻烦的事情.
所以就想到运营个名言警句和新闻的抖音号.

因为名言警句和新闻是可以爬的, 这样自动生成视频.

在这里插入图片描述
csdn发不了视频, 大概就是这样的,
1.文字自动生成图片居中,
2.自动把文字读出来生成语音,
3.把图片和文字合成mp4文件;

下面是抖音号, 可以点开url看下视频效果:

1.生成图片, 文字居中

sum_width = 1125
sum_height = 2436

def create_pic(number, text):
    text = handle_text(text)
    if len(text) > 0:
        im = Image.new('RGB', (sum_width, sum_height), (255, 255, 255))
        font = ImageFont.truetype(os.path.join("fonts", "msyh.ttf"), 150)
        dr = ImageDraw.Draw(im)
        w, h = dr.textsize(text, font)
        dr.text(((sum_width - w) / 2, (sum_height - h) / 2), text, font=font, fill='#000000')
        # im.show()
        im.save('pic/' + number + '.png')

def handle_text(text):
    try:
        result = ''
        array = cut(text, 6)
        for v in array:
            result = result + v + '\n'
        array = result.split('。')
        result = array[0] + '。\n' + array[1]
        return result
    except:
        return ''

def cut(obj, sec):
    return [obj[i:i+sec] for i in range(0,len(obj),sec)]

2.文字生成语音

使用最niubi最像人的ai合成语音库(azure TTS API)
github

def create_audio(number, text):
    cmd = 'python3 -m aspeak -t "{}" -l zh-CN -o audios/{}.mp3 --mp3'.format(text, number)
    os.system(cmd)

3.图片+语音合成视频

import cv2
from moviepy.editor import VideoFileClip, AudioFileClip
from mutagen.mp3 import MP3

def create_video(number):
    pic_path = ('pic/' + number + '.png')
    audio_path = ('audios/' + number + '.mp3')
    video_path = ('videos/' + number + '.mp4')
    pic_frame = cv2.imread(pic_path)

    img_size = (sum_width, sum_height)
    fourcc = cv2.VideoWriter_fourcc(*'mp4v')
    videoWriter = cv2.VideoWriter(video_path, fourcc, 1, img_size)
    audio_time_count = get_audio_time_count(number)
    print('audio time: ', audio_time_count)
    for i in range(audio_time_count):
        videoWriter.write(pic_frame)
    videoWriter.release()

    video = VideoFileClip(video_path)
    video_clip = video.set_audio(AudioFileClip(audio_path))
    video_clip.write_videofile(video_path)

def get_audio_time_count(number):
    audio = MP3('audios/' + number + '.mp3')
    time_count = int(audio.info.length)
    return time_count
