[theora-dev] getting ready for alpha 3

[Mauricio Piacentini]

Just to let you know that the transcoder sample is not yet producing a fully
functional theora file. The frame data is actually ok, but the granulepos is
still not right. This will translate as a series of small freezes when
playing a transcoded stream in the player, since the granulepos will be
wrong after a keyframe, something like this if you are monitoring the
current stream time (pseudo values in secs  of course)

1.1
1.2
1.3
1.4
0.7
0.8
1.8
1.9
2.0
...

etc. Probably something simple needs to be changed in the transcoder, I will
have a look at it again in the near future.

Regards,
Mauricio
