[gst-devel] Real Video conversion?

[Matej Cepl]

Hi,

is something like that possible. I got this Real file (my father's lecture
somewhere) which when run through ffmpeg (the only way I know how to
decipher what's the content of the file; is there some more gstreamer-like
way?) gives this:

I hoped that pitfdll could work (I have even find freshrpms package for my
Fedora Core 6), but it apparently doesn't support RV30:

Is there a way how to convert my .rm file to something more common (final
result should be readable by my father on WinXP just with WMP, so MPEG/AVI
with MSMPEG4/MP3 would be very fine;
http://ffmpeg.mplayerhq.hu/compat.html)? Can anybody suggest at least some
other way how to get inside of this file? Do I have to use mplayer for
that? How to do it?

Thanks a lot for any reply,

Matěj Cepl
