我想將'Open_Buffer_Continue'函數添加到MediaInfoDLL.py ctypes包裝器中，這里的綁定和MediaInfoDLL.cs C＃綁定已經實現了此功能，因此是可能的。我如何通過以下內容：file = open('./file.avi', 'rb')到mediainfo cpp Open_Buffer_Continue，它期望：( const ZenLib::int8u * Buffer, size_t Buffer_Size ) ？這是我到目前為止所擁有的：MediaInfo_Open_Buffer_Init = MediaInfoDLL_Handler.MediaInfo_Open_Buffer_InitMediaInfo_Open_Buffer_Init.argtype = [c_size_t, c_size_t]MediaInfo_Open_Buffer_Init.restype = NoneMediaInfo_Open_Buffer_Continue = MediaInfoDLL_Handler.MediaInfo_Open_Buffer_ContinueMediaInfo_Open_Buffer_Continue.argtype = [c_size_t, c_size_t] # NOT SURE HERE var 1MediaInfo_Open_Buffer_Continue.restype = c_size_tMediaInfo_Open_Buffer_Finalize = MediaInfoDLL_Handler.MediaInfo_Open_Buffer_FinalizeMediaInfo_Open_Buffer_Finalize.argtype = [c_void_p]MediaInfo_Open_Buffer_Finalize.restype = None

我對此一無所知mediainfo，但看起來好像ZenLib::int8u*是一個指向字節的指針，所以最好使用的是：
MediaInfo_Open_Buffer_Continue.argtype = [c_char_p, c_size_t]
然后將文件讀入字符串并將其傳遞：
with open('./file.avi','rb') as f:
data = f.read()
MediaInfo_Open_Buffer_Continue(data,len(data))
