Re: [Sugar-devel] MP4 playback on XO-1.75?

I tried compiling ffmpeg on 12.1.0 os6 but it seems gcc or my hardware is buggy because gcc segfaults during the compilation. I used the source rpm from rpmfusion. I'll be posting about this some more on olpc devel. I can also report that Firefox 10 on os6 has a webm codec but it doesn't seem to work on youtube. I haven't looked at why. ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Look to those projects for hints about where to get the software codecs compiled for ARM. My feeling is the processor will struggle decoding even moderate resolution h.264 without the hardware acceleration. A friend is looking at getting the hardware acceleration stuff working on the XO, it is apparently complicated because the kernel for which Marvel released their drivers is quite different to that in 11.3.1. I'll catch up with him tomorrow and see what progress he has made on the 12.1.0 kernel. ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Please do keep me/us in the loop about the findings you and your friend make as I'm sure many other people here are also interested in this work. :-) Cheers, Christoph -- Christoph Derndorfer volunteer, OLPC (Austria) [www.olpc.at] editor, OLPC News [www.olpcnews.com] contributor, TechnikBasteln [www.technikbasteln.net] e-mail: christ...@derndorfer.eu ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel
