Re: [Iaxclient-devel] [iaxclient] image format

[Bill C. <bc...@ya...>]

Hi Paulo,

It depends on what you mean by support. If a video capture device provides images in this format (rgb24), iaxclient can get these images. But, they will have been converted to one of the three formats you mentioned.

Libvidcap, which performs the capture and conversion, has conversion functions in its external api which convert from each of these three format to the remaining two. Internally, however, it has conversion functions to convert from internally-supported (at capture time) formats (rgb555, yvu9, 2vuy, rgb24) to the three formats it exposes.

If you're looking to get the captured images in an rgb24 format, one of libvidcap's internal functions could be adapted to convert from rgb32 to rgb24.

Does this help?

Regards,
Bill

 Hi, 
Iaxclient 2.0.1 (with video) doesn't support MEDIASUBTYPE_RGB24 (Windows IA-32) color format?right?
 
I saw support just for (sub-sampled ones) : 
#defineIMAGE_FORMAT_I420    0x30323449
#defineIMAGE_FORMAT_IYUV    0x56555949
#defineIMAGE_FORMAT_YUY2    0x32595559
 
Is this a theora's encoding requirement?
 
Thanks 
Paulo
