I am trying to convert DirectX surfaces (usually ARGB8) to FFMPEG X264 (requires YUV420) and I am suprised to see that particular conversion missing. It looks like most of the conversions expect no alpha channel to be present.</DIV><DIV></DIV><DIV>What I was hoping for is :</DIV><DIV> ippiRGBToYUV420_8u_AC4P3R()</DIV><DIV></DIV><DIV>I tried removing the alpha channel from my source RGB surface, but DirectX9 render targets or plain surfaces don't support R8G8B8 formats.</DIV><DIV></DIV><DIV>Thanks,</DIV><DIV></DIV><DIV>-Justin</DIV> Thu, 07 Jul 2011 01:58:29 GMT https://community.intel.com/t5/Intel-Integrated-Performance/IPP-Color-Conversion-from-DirectX-Formats-to-X264-Formats/m-p/793017#M2570 jpbischo 2011-07-07T01:58:29Z https://community.intel.com/t5/Intel-Integrated-Performance/IPP-Color-Conversion-from-DirectX-Formats-to-X264-Formats/m-p/793018#M2571 Try ippiRGBToYCbCr411_JPEG_8u_C4P3R Thu, 07 Jul 2011 22:46:19 GMT https://community.intel.com/t5/Intel-Integrated-Performance/IPP-Color-Conversion-from-DirectX-Formats-to-X264-Formats/m-p/793018#M2571 oxydius 2011-07-07T22:46:19Z
