The likes of libshout and icecast could pass mpeg4 straight through but without timing so it would run far too quickly for streaming. However with some modifications to something like oggfwd or ezstream you could get a feed from mplayer to do the timing. Needs checking up on though to make sure it works well enough. karl.

Hello folks!!! I'm happy, i do it! I've broadcast mpeg4 and i choose following method ffmpeg2theora -v 10 -a -1 -x 384 -y 256 /mnt/hdc/movie/godsend.avi -o /dev/stdout | oggfwd xxx.xxx.xxx.xxx 8899 hackme /video.ogg But ffmpeg2theora have very big CPU load average and if use source package of oggfwd and compile, oggfwd crashes with Segmentation fault, but if you download binary of oggfwd it works correct.

Alexey Pogosov wrote:> But ffmpeg2theora have very big CPU load averageyes, it is substantial. but afaik not much optimization work has gone into theora yet, so there's hope. i heard some guys on irc mention theora-mmx, which makes use of the pentium's simd instructions. it's somewhere in svn.xiph.org. haven't tried it myself yet, but it might reduce the load somewhat.
