问题描述

因此，我尝试编写一些从ftp下载的视频文件的脚本，然后将其发送到手刹进行编码.

So I am trying to script some video file downloads from my ftp and send them to handbrake for encoding.

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

I was having trouble with keeping the ftp socket open, but due to an amazing response from a SO user that is solved but:

现在，手刹无法识别正在下载的文件.在实施套接字解决方案之前，这个特定的文件编码良好，因此与如何将数据写入文件有关.

Now the file that is getting downloaded is not recognized by handbrake. This particular file encoded fine before I implemented the socket solution so its something to do with how the data is being written to the file.

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)

这是downloadFile函数代码:

here is downloadFile function code:

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()

这是handbrake.py:

here is 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)

这是我从握手获得的输出

and here is the output I get from handrake

HandBrake has exited.

更新:好的，我已经接近了，我已经确定原来的传输是在BINARY中传输的，现在是ASCII中的TRANSFERRING.一旦弄清楚如何将其设置回BINARY，就可以了

UPDATE: Ok I'm closer, I have identified that the original transfer is transferring in BINARY and this is now TRANSFERRING in ASCII. Once I figure out how to set it back to BINARY we should be ok
