 * file I/O interface on a file or live source.

open
    Open a local file or URL.
    Arguments:
        fileName [in] File name or url to open.
                      To open the movie source file, just set file name to NULL.
                      To open another external file for some track (eg. MP4), set the url.

        mode [in] Open mode, same as libc. Such as "rb".

    Return value:
        Handle of the opened file. NULL for failure.

read
    Read data from the file.
    Arguments:
        handle [in] Handle of the file.
        buffer [in] Pointer to a block of memory, to receive the data.
        size[in] Data size to read, in bytes.

    Return value:
        The total number of bytes successfully read.
        If this number differs from the size parameter, either an error occurred or the EOF was reached.


seek
    Seek the stream.
    Arguments:
        handle [in] Handle of the file.
        offset [in] The offset.
                    To move to a position before the end-of-file, you need to pass a negative value in offset and set whence to SEEK_END.

        whence in]  The new position, measured in bytes from the beginning of the file,
                    is obtained by adding offset to the position specified by whence.
                    SEEK_SET - Set position equal to offset bytes.
                    SEEK_CUR - Set position to current location plus offset .
                    SEEK_END - Set position to end-of-file plus offset.
    Return value:
        Upon success, returns 0; otherwise, returns -1.

tell
    Tell the position of the file pointer
    Arguments:
        handle [in] Handle of the file.

    Return value:
        Returns the position of the file pointer in bytes; i.e., its offset into the file stream.
        If error occurs or this feature can not be supported (eg. broadcast application), returns -1.

size
    Tell the size of the entire file.
    Arguments:
        handle [in] Handle of the file.
    Return value:
        Returns the file size in bytes.
        If error occurs or this feature can not be supported (eg. broadcast application), returns -1.

check_available_bytes
    Tell the availble bytes of the file. Especially useful for a live source file (streaming).
    The parser can decide not to read if cached data is not enough and so avoid reading failure in unexpected context.
    For a local file, any bytes request from the parser can be met as long as it's within the file range.

    Arguments:
        handle [in] Handle of the file.
        bytes_requested [in]    Bytes requested for further parsing. This information can help the application
                                to cache enough data before calling parser API next time.
                                If the parser can not know the exact data size needed, set it to 0.

    Return value:
        If the file source can always meet the data reading request unless EOF (eg. a local file or a pull-mode live source),
        returns the data size from the current file pointer to the file end.

        Otherwise (eg. a push-mode live source), returns the cached data size.
        If error occurs or this feature can not be supported (eg. broadcast application), returns -1.

close
    Close the file.
    Arguments:
        handle [in] Handle of the file.

    Return value:
        Upon success, returns 0; otherwise, returns -1.

RequestBuffer
    Request an output buffer.

    Arguments:

        size [in,out] The requested buffer size as input, and the size actually got as output, both in bytes.

                      make full use of the buffer.

        bufContext [out] A buffer context from the application. The parser shall not modify it.

        bufContext [in] The buffer context from the application, got on requestBuffer().
