Re: Ripping theora stream

The problem of fast playing was a fault in writing down the packets. I set
up granulepos = 0 for all packets, most players didn't even open the file,
only mplayer open/play the file ad maximum speed.

I solved the problem checking if a packet is a keyframe using:

th_packet_iskeyframe(&op)

and adjusting consequently granulepos.

Such solution is not very fast but the ogg file produced seems to be ok and
seekable.
