问题
In the Microsoft DirectShow documentation there appear to be no RGB video or image formats with more than 8 bits per channel. There are some YUV formats with 10 or 16 bits per channel but I've not found much support for them by googling.
- Video Subtype GUIDs
- 10-bit and 16-bit YUV Video Formats
Are there any supported DirectShow formats or FourCC video or image formats (third party or not) for greater definition than 8 bits per channel?
回答1:
DirectShow itself - as the framework - has no problems supporting 10 bpp and more, it's a matter of video renderers and video adapters to support these formats. Some professional hardware from Balckmagic definitely supports 10 bpp formats, including within DirectShow API.
