Question

所以我试图编写一些来自我的ftp的视频文件下载并将它们发送到手刹以进行编码。

我在保持ftp套接字打开方面遇到了麻烦，但是由于SO用户的惊人响应已经解决但是：

现在手刹不能识别下载的文件。在我实现套接字解决方案之前，这个特殊的文件编码很好，所以它与数据如何写入文件有关。

这是我的代码：

if ext in validExtensions:
        print("Downloading new file: " + fil)
        downloadFile(fil, newPath)
        print("Download complete. Encoding: " + fil)
        hb(newPath + f)

这里是downloadFile功能代码：

def downloadFile(filename, folder):
    myhost = 'host'
    myuser = 'user'
    passw = 'pass'
    #login
    ftp = FTP(myhost,myuser,passw)
    ftp.set_debuglevel(2)
    sock = ftp.transfercmd('RETR ' + filename)
    def background():
        f = open(folder + filename, 'wb')
        while True:
            block = sock.recv(1024*1024)
            if not block:
                break
            f.write(block)
        sock.close()
        f.close()
    t = threading.Thread(target=background)
    t.start()
    while t.is_alive():
        t.join(60)
        ftp.voidcmd('NOOP')
    ftp.quit()

这里是handbrake.py：

def HandbrakeEncode(filepath):
    import subprocess
    import os
    filename = os.path.basename(filepath)
    file, ext = os.path.splitext(filename)
    outputPath = "D:\\Converted Mp4\\" + file + ".mp4"
    args = '-i ' + filepath + ' -o '+ outputPath

    #Popen expects arguments borken up into chunks by spaces
    cmd = ['C:\\Program Files\\Handbrake\\HandbrakeCLI.exe',
           '-i', filepath,
           '-o', outputPath,
           'preset="AppleTV 2"']


    p = subprocess.call(cmd)
    #delete the original
    os.remove(filepath)

这是我从handrake获得的输出

HandBrake has exited.

更新：好的我离我更近了，我发现原来的传输是在BINARY中传输的，现在这是ASCII中的TRANSFERRING。一旦我弄清楚如何将其设置回BINARY，我们应该没问题

我的解决方案是在执行转移之前发送一个明确的“TYPE I”命令

希望这有助于其他人新代码：

ftp = FTP(myhost,myuser,passw)
    ftp.sendcmd('TYPE I')
    ftp.set_debuglevel(2)
    sock = ftp.transfercmd('RETR ' + filename)
    def background():
        f = open(folder + filename, 'wb')
        while True:
            block = sock.recv(1024*1024)
            if not block:
                break
            f.write(block)
        sock.close()
    t = threading.Thread(target=background)
    t.start()
    while t.is_alive():
        t.join(60)
        ftp.voidcmd('NOOP')
