re all,
these days we're busy on freej development with a final release
hopefully due in july, including a full suite for video compositing
and streaming in javascript (xulrunner 1.9) and python (c++ -> swig),
see debian pkgs: http://packages.debian.org/sid/libfreej-dev
we will also have a carbon/osx (and native quicktime) free graphical
client to stream theora to icecast on apple computers.
by now things are mostly in place, while we are going through a picky
debugging session.
i'm writing you because we noticed that, altough working, the
streaming of ogg/theora 1.0 is not correctly timed on the player side
when using icecast2 and the ffmpeg2theora encoder (theorautils.c):
using various players as vlc, mplayer, xine and firefox 3.5 the client
plays too fast the incoming frames (without fps synchronisation
basically) until reaching 0 latency with the stream source, then stops
(or crashes even).
further research on the topic has shown that the ogg mux code in vlc
(vlc/modules/mux/ogg.c) sets a lot more variables (pts, dts and the
granular shift calculus) that seem to be disregarded in old code (that
used to work) as ffmpeg2theora/theorautils.c
now the question: are there documented code examples for streaming to
handle correctly timing issues? and if not, is there an existing
source code that can be considered a correct reference, something like
the mux code of vlc, gstreamer, ffmpeg2theora or oggfwd?
thanks for your support and cheers to the 1.1 release, i'll be testing
that soon.
ciao
