I've compiled the IJL2.0 sample and it's possible to extract them but only if the JPEG is encoded as 4:2:2 - I'd like to be able to handle different formats, e.g. a JPEG encoded as YUV 4:1:1.</DIV> <DIV></DIV> <DIV>If Iuse the IPPlibrary Icould convert the RGBvalues decoded from the JPEG to YUV but this seems wasteful when they were YUV to start with in the JPEG. Am I missing something?</DIV> Mon, 16 May 2005 17:57:10 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Extracting-YUV-data-from-a-JPEG/m-p/990788#M22276 mark_moore 2005-05-16T17:57:10Z https://community.intel.com/t5/Intel-Integrated-Performance/Extracting-YUV-data-from-a-JPEG/m-p/990789#M22277 <DIV>Hi Mark,</DIV> <DIV></DIV> <DIV>In case of IJL you can set unknown color space for the output data of decoder to turn off color conversion</DIV> <DIV></DIV> <DIV>Regards,</DIV> <DIV> Vladimir</DIV> Wed, 18 May 2005 01:37:42 GMT https://community.intel.com/t5/Intel-Integrated-Performance/Extracting-YUV-data-from-a-JPEG/m-p/990789#M22277 Vladimir_Dudnik 2005-05-18T01:37:42Z
