  Enabling floating-point in DirectX plug-ins

  Posted by Frederic Baumann on January 4, 2011 at 10:08 pm

  Hi,

  I am writing a plug-in the old-way, i.e. with DirectX (instead of OFX).

  Everything is working almost fine except that my plug-in appears in the video effects list with the symbol showing that it does not allow floating-point pixels, and indeed, all the processing I wrote handles BYTE-based RGB colors only.

  Would you know what is the flag to set, to enable the handling floating-point colors? I mean, in such a way that the plug-in is recognized as being able to handle floating-point colors?

  I managed to enable the multithreading with the SFVIDEOPLUGIN_CAPS_CLONEABLE flag, I have read the whole SDK documentation, but could not find any information regarding floating-point handling.

  Help will be appreciated!

  Thanks in advance,
  Frédéric

  From my findings, it is:

  #define SFVIDEOPLUGIN_CAPS_RGBFLOAT 0x00000800

  Note, that after this flag you cannot use anymore CSFARGBReadWritePtr class. A new class is required.

  If you recompile a plugin, then delete a key in the registry, so that Vegas recognizes it as a floating-point enabled plugin:

  HKEY_CURRENT_USER\Software\Sony Creative Software\Vegas Pro\10.0\Metrics\DXImageTransCache.1
