Oh, such a whirlwind. First Boltzmann told me it's all about distributions and then Newton told me it's all about initial conditions. Who to believe?

Anyway, I re-based my speedup code on slipstream 43, which seems pretty stable. I still reduce demux time for the video from 3:26 to 0:58 for a representative disk. I would like to put the code back under an INI option so that it doesn't diverge from the main line again. Is that all right, Rocky?

Distributions and initial conditions are the same thing. There is no abstract distribution divorced from a specific sampling of reality, and such a sampling can itself be taken as a set of initial conditions given at a specific time.

Go ahead and integrate your stuff (use Commit on the VisualSVN pulldown). When you have everything supported, we can publish the INI setting so that our great users can test it out. 3:26 -> 0:58 sounds great. Git 'er done!

Let me guess:

Speedup=0/1

Silly billies, only DGDemuxGUI reads the INI file, so there has to be an option to DGDemux: maybe -fast.

And then in DGDemuxGUI, if you hold down the shift key when pressing the Show or Demux buttons, the -fast option is issued. That way we don't have to create a new option line in the GUI (which would just have to be removed down the road) while still being able to go fast or slow without needing to edit the INI file or exit the GUI.

Great idea, Britney. I implemented that and hopefully Rocky will include it in the next slipstream. I'll keep adding to it until all the stream types are supported in fast mode. Then when we switch everything over we will have fast mode by default.

BTW, I demuxed the AC3 stream from 1917:

old mode: 3:46 secs
fast mode: 0:32 secs
Seems like a useful development. :belly-laugh:

BTW, I found a little bug in build 43. DV streams are not marked as DV (regression from the fix to not show PIP as DV). Say thank you.
