Sending YUV data to a pipe under windows

[petebleackley]

I want to decode some video with VLC, and pipe YUV data to another application for processing. So far my command line looks like.

"c:\program files\videolan\vlc\vlc" --vout=yuv --yuv-file=//- --yuv-yuv4mpeg2 file.mpg | MyApp

What should the value of --yuv-file be to ensure that the decoded data is sent to MyApp correctly?

I'm currently using the command line

C:\Python27>"c:\program files\videolan\vlc\vlc" --vout=yuv --yuv-yuv4mpeg2 --sout=file/raw://- \python27\antiques_roadshow.mpg vlc://quit | MyApp

This seems to pipe the data correctly, but the yuv4mpeg headers are missing from the data, and MyApp needs them. I thought that --yuv-yuv4mpeg2 was the correct option to turn them on. Can anyone tell me what to do?

vout=yuv does send only the raw yuv data, with no yeaders.
Why not transcode to huffyuv or something like I420 ?
