16 years agoHi,
--- Quote Start --- Please refer the site http://www.slscorp.com/pages/neekbsp.php . --- Quote End --- Hmm, looks like they want some login & password, which i don't have to download anything from there... :( Any other link avaliable? --- Quote Start --- Not yet. Would you tell me the method of compilation? Can we do it only by selecting in the 'menuconfig'? --- Quote End --- I have no idea, wheater it's now in a uCLinux environment. I'm using a pretty old uCLinux, where it was not included (but it looks like my uClinux uses the same gcc: V3.4.6). So i took the tarball directly from the sourceforge link (see my 1st Post, followed "Download" link and took the newest Version 0.5.1) , untarred it (tar -xzvf libmpeg2-0.5.1.tar.gz) and used the mentioned commandline to configure and build it. It doesn't change anything outside its directory if you dont do a "make install". After configuring and building, i just copied the mpeg2dec binary from libmpeg2-0.5.1/src/ to a directory, wich i'm able to access from my nios system via nfs. It's a self designed custum board, doing some MPEG-TS processing on a EP2C35, and it would be a really nice feature, to be able to decode some pictures. Of course it's far from realtime, but a single picture every 10-20 sec or so would be totally sufficient. I've already tried older versions of mpeg2dec and different (also no) optimizations for gcc - result looks always the same. Meanwhile i also build it with a crosscompiler for a coldfire processor, which like nios doesnt have any MMX or SSE extentions - the resulting binary worked fine! I'm getting really confused now... Cheers WK
