树莓派 播放badapple

很困 随便写写

一，准备：

屏：oled  128*64 spi接口 sh1106驱动

树莓派 4 kali系统

python3

跳线若干

二，接线

gun接gun

vcc接3v3

clk接spisclk

mos接spimosi

res接gpio17

dc接gpio22

cs接spice0

三，准备材料

随便去哪下载个badapple mp3格式

找个软件把视频分帧 分成一个一个的图片

然后用格式工厂把视频的音乐分出来

你要懒得下用以下代码也可以（不推荐）

import cv2
from moviepy.editor import *
videos_src_path = "C:\\Users\\Administrator\\Desktop\\12"#视频文件夹
video_formats = [".mp4", ".MOV"]#视频可选格式
frames_save_path = "C:\\Users\\Administrator\\Desktop\\save"#图片保存文件夹
width = 128#宽
height = 64#高
time_interval = 29#需要的帧数


def audio():


    video = VideoFileClip(videos_src_path+'\\1233.mp4')  # 视频所在路径
    audio = video.audio
    audio.write_audiofile(frames_save_path+'\\1.mp3')  # 音频所在路径




def video2frame(video_src_path, formats, frame_save_path, frame_width, frame_height, interval):
    """
    将视频按固定间隔读取写入图片
    :param video_src_path: 视频存放路径
    :param formats:　包含的所有视频格式
    :param frame_save_path:　保存路径
    :param frame_width:　保存帧宽
    :param frame_height:　保存帧高
    :param interval:　保存帧间隔
    :return:　帧图片
    """
    videos = os.listdir(video_src_path)

    def filter_format(x, all_formats):
        if x[-4:] in all_formats:
            return True
        else:
            return False

    videos = filter(lambda x: filter_format(x, formats), videos)

    for each_video in videos:
        print("正在读取视频：", each_video)

        each_video_full_path = os.path.join(video_src_path, each_video)

        cap = cv2.VideoCapture(each_video_full_path)
        vc=cap
        fps = vc.get(cv2.CAP_PROP_FPS)  # 获取帧率
        print(fps)  # 帧率可能不是整数 需要取整
        fps=round(fps)

        frame_index = 0
        frame_count = 0
        if cap.isOpened():
            success = True
        else:
            success = False
            print("读取失败!")

        while (success):
            success, frame = cap.read()
            print("---> 正在读取第%d帧:" % frame_index, success)
            if ((frame_index % round(fps/interval) == 0) or interval>=fps) and success:
                resize_frame = cv2.resize(frame, (frame_width, frame_height), interpolation=cv2.INTER_AREA)
                resize_frame = cv2.cvtColor(resize_frame, cv2.COLOR_BGR2GRAY)
                ret, resize_frame = cv2.threshold(resize_frame, 150, 255,cv2.THRESH_BINARY)
                cv2.imwrite(frames_save_path+'//'+str(frame_count)+"p.jpg", resize_frame)
                print("已经存取第%d帧:" % frame_index)
                frame_count += 1

            frame_index += 1

    cap.release()


if __name__ == '__main__':
    #video2frame(videos_src_path, video_formats, frames_save_path, width, height, time_interval)#拆分出图片
    audio()#拆分出声效

代码都是网上下载的 我做了些更改  你们需要改啥上面都有写 

然后上传图片和音效至树莓派的 最好放在不同的文件夹 看好自己的权限

四，更改树莓派配置文件

树莓派连接hdmi时 默认是声音不从3.5mm口走

更改 /boot/config.txt 加填 dtparam=audio=on

调大音量 试播音频 如果没有试下非root账户

五，代码

from luma.core.interface.serial import spi
from luma.oled.device import ssd1306, ssd1325, ssd1331, sh1106
from PIL import Image
import os,threading
from playsound import playsound
import time

class pyAU(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
        pass
    def run(self):
        playsound('/root/apple-mp3/apple.mp3')#声音文件目录
        pass


serial =spi(gpio_DC=22,gpio_RST=17,device=0, port=0)
device = sh1106(serial)  # ssd1306, ssd1325, ssd1331, sh1106
path='/root/apple-img'#图片目录
a=os.listdir(path)
device.clear()
time.sleep(1)
pyAU().start()

fps=54#帧率进行微调与声音同步
try:
    for i in range(len(a)):
        im=Image.open(path+'/'+str(i)+'p.jpg').convert('1')

        device.display(im)
        time.sleep(1/fps)
finally:
    device.clear()
    

以上没包的自行pip3 install 安装

不推荐用py进行视频分帧和取音频

以上。。。
