ogg dev - Mar 2009 - frame length

?Greetings,

I am new to this forum and also to programming in general. I have desire
to try to use Ogg as my default streaming encoder.  I have a quick
question. How does someone determine a frame length in ogg? For example
if I was to use an mp3 frame, I would try to do something like this:
frameSz = 144 * BitRate / (SampleRate + Padding). Also is there a
tutorial on how to correctly use the libraries. The example are a little
vague.

Vorbis uses a variable frame length, and all the compressed packets
are variable size. As such it requires external framing from the
container to find the packet boundaries. ogg_packet::bytes is the the
only way to tell where the boundaries are.
