https://community.intel.com/t5/Intel-Integrated-Performance/decode-MPEG-4-to-a-specified-buffer/m-p/886493#M10885 Hi!<BR /><BR />I would like to decode an MPEG-4 stream and render it to an RGB24 buffer. The buffer pointer comes from an outer source. Can anyone explain the correct way of doing this with UMC 5.3? I have some problems with understanding the steps of the process. <BR />First I initialize the decoder, and I specify a VideoProcessing instance as pPostProcessing. The VideoProcessing instance has been inited with a VideoProcessingParams instane (InterpolationMethod = IPPI_INTER_LINEAR, m_DeinterlacingMethod = UMC::NO_DEINTERLACING and source crop area set to the whole picture).<BR />I get MPEG-4 data from an outer source as a pointer and length parameter. I set the input MediaData's buffer pointer to this data. I also have a pointer to an output buffer and I set the output VideoData's pointer to this pointer . I specify the resolution and thecolor format(RGB24) for the VideoData buffer, before decode. Can I use this code without renderer?If yes, can you specify exactly how to do this? If not can you explain how can I use the renderer for this purpose?<BR /><BR />Best Regards,<BR />Miki<BR /><BR /> Mon, 19 May 2008 15:47:29 GMT bendeguy 2008-05-19T15:47:29Z https://community.intel.com/t5/Intel-Integrated-Performance/decode-MPEG-4-to-a-specified-buffer/m-p/886493#M10885 Hi!<BR /><BR />I would like to decode an MPEG-4 stream and render it to an RGB24 buffer.

It works well.<BR />Regards,<BR />Miki<BR /> Tue, 20 May 2008 13:05:29 GMT https://community.intel.com/t5/Intel-Integrated-Performance/decode-MPEG-4-to-a-specified-buffer/m-p/886494#M10886 bendeguy 2008-05-20T13:05:29Z https://community.intel.com/t5/Intel-Integrated-Performance/decode-MPEG-4-to-a-specified-buffer/m-p/886495#M10887 Care to post a link to this information?<BR /> Tue, 20 May 2008 20:42:36 GMT https://community.intel.com/t5/Intel-Integrated-Performance/decode-MPEG-4-to-a-specified-buffer/m-p/886495#M10887 lycono 2008-05-20T20:42:36Z https://community.intel.com/t5/Intel-Integrated-Performance/decode-MPEG-4-to-a-specified-buffer/m-p/886496#M10888 Here's the link:<BR /><A href="https://community.intel.com/en-us/forums//topic/57218">http://software.intel.com/en-us/forums//topic/57218</A><BR /><BR />BR,<BR />Miki<BR /> Wed, 21 May 2008 08:38:15 GMT https://community.intel.com/t5/Intel-Integrated-Performance/decode-MPEG-4-to-a-specified-buffer/m-p/886496#M10888 bendeguy 2008-05-21T08:38:15Z
