@ogg.k It sounds good to me. Could you tell me how to create on-the-fly live video streaming? What program should i installed? @Narendra The advantages maybe if you want to monitor a lot of room (like security control room) or for multi-angle live stream. But it's just my opinion, and dosen't proved yet Thx before Pandu Rakimanputra 2010/3/21 narendra sisodiya <narendra.sisodiya at gmail.com>:> > > On Sun, Mar 21, 2010 at 9:02 PM, ogg.k.ogg.k at googlemail.com > <ogg.k.ogg.k at googlemail.com> wrote: >> >> > As written on my subject, is it possible to do on-the-fly video >> > multiplexing with OGG?

[ogg-dev] On-the-Fly multiplexing Video
> It sounds good to me. Could you tell me how to create on-the-fly live > video streaming? What program should i installed?I suggest you start by downloading, and reading the documentation (including, but not limited to, the output of any --help option, files in the doc tree, README files, etc) of the following: ffmpeg2theora liboggz (including oggz-merge) oggfwd In case you want to ask where to find them, Google knows. In particular, ffmpeg2theora's --help output contains an example of live streaming from a v4l input using other tools and pipes. You should be able to get it from there using some of the oggz tools, and maybe named pipes.
