This fixes PCR drift due to accumulating TS_PACKET_SIZE*8*90000LL/ts->mux_rate each packet, due to rounding errors when mux_rate does not evenly divide 135360000.
This patch also increases the PCR precision to 27 MHz from 90 kHz and takes the location of the PCR data into account (+11 bytes according to the spec).

Patch by avcoder, ffmpeg gmail

Originally committed as revision 25859 to svn://svn.ffmpeg.org/ffmpeg/trunk

Wraparound in ssd is mainly avoided by subtracting the ssd of the
best node from all the others once it has grown large enough.

If using very large trellis sizes (e.g. -trellis 15), the frontier
is so large that the difference between the best and the worst is
large enough to cause wraparound, even if the ssd of the best one
is subtracted regularly.

When using -trellis 10 on a 30 second sample, this causes only a slight
slowdown, from 61 to 64 seconds.

This reverts snprintf->av_d2str part of r20840.
With it, track number is exported as a float, which is not
