Hello, I am looking into reducing memory usage for OpenJPEG.(how I spent my Christmas holidays :) )
So far, I have managed to halve memory usage for high bit rate decoding, for example. 1920x1080 single tile lossy-compressed image at 9:1 compression. And there is more low hanging fruit..... I have a pull request submitted for my omnibus branch. This branch includes performance and memory improvements: 1) OpenMP support: multi-threading built into the library 2) encoding perf improvements 3) memory mapped file support and drastic reduction in decode memory usage All unit tests and memory leak tests have passed for this branch. If these changes sound useful to you, please show your support by either posting on the OpenJPEG news group: https://groups.google.com/forum/#!forum/openjpeg or commenting on the pull request: https://github.com/uclouvain/openjpeg/pull/683 The project maintainers need "encouragement" to get new features merged into the master. Thanks and Happy New Year, Aaron
