thank you for answer.
I will explain all to you.
1. input file(maybe... mxf file)
2. demuxing & decoding file
3. extract buffer in file and encoding
4. muxing and create output file(maybe... mxf file)
I want to that use LeadTools.
but I don't know control buffer.
I want to input and output buffer.
support me...(example or website...)

How to MXF file demuxing and muxing?
I see Leadtools sample source
LEAD Technologies\LEADTOOLS 17\Examples\Ltmm\Cpp\Convert
but I guess it is not demuxing and muxing.
if "Target Format" is muxing?
if true... where demuxing?
and an appendix,
I want to put in metadata in creating MXF file
or I want to see metadata in input MXF file.
thanks.

Do you mean that you want to specify the type of input (source) file so that a suitable demux is used?
In general, if you provide our convert control with a valid multimedia file as a source file, it will automatically choose a suitable demux and decoder. You only need to specify the target format (Mux) and encoder.
However, if you have more than one demux or decoder for a certain format and want to be able to choose one of them and not leave it to the automatic features, you can do that using the ltmmConvertCtrl.SetPreferredFilter method. For more information, please see the help topic "ltmmConvertCtrl.SetPreferredFilter Method" in the LEADTOOLS Multimedia help file.

The mxf demuxer will parse the video/audio samples from the source mxf file. It should also provide you a way to extract the metadata (DM) from the source mxf file.
Your transcoding filter receives the video/audio samples from the demuxer, does the transcoding, and then feed the output video/audio samples to the mxf muxer, and also the metadata.
The mxf muxer filte should know how to generate the destination mxf file for you.

Our MXF Mux and Demux provide the functions needed for working with metadata through their COM interfaces, which are documented in our LEADTOOLS Multimedia help files.
The following forum post gives an example on how to obtain these interfaces:
