    Might help if you tell why, as not everyone is familiar with ReClock (it is rather geeky ;))

    Doesn't the "Dynamic Refresh Rate" built into MP the same thing as reclock?

    AW: Re: SAF v5.00 experimental (based on FFDShow DXVA decoder)

    @Hoborg,

    5.1 question.

    We talked about it some days ago via ICQ.

    The problem is, that ffdshow in the MP My TV Section doesent work correctly.

    The amplifier signals an 5.1 decoded TV Stream with a blue lamp, but the Subwoofer doesnt work.

    It seems that the LFE Signal is bad.

    This behaviour in only on TV.
    5.1 Videos are working fine.

    Problem with SP/DIF passthrough?

    Record a sample and try it to play in graphstudio. Is playback OK?

    ALL:
    Guys, what do you think about integration of ReClock in to SAF?

    What is the advantage fo reclock?

    The purpose of ReClock Directshow Filter is to definitely get rid of jerky playback of video material(AVI, MKV, DVD, Blu-ray, etc) on a PC or a PC connected to a TV or Projector. It's a DirectShow filter which is loaded in place of the default directsound audio renderer.

    Might help if you tell why, as not everyone is familiar with ReClock (it is rather geeky ;))

    For example my HTPC->LCD TV is connected by DVI and my TV work only in 60Hz from DVI source. I did some test and setup reclock to "reclock" all videos to 30fps.
    Now my 23.976 fps movies play really nicely in all DirectShow based players (graphstudio,GB-PVR, etc...)
    I was surprised it works even for LiveTV (if configured correctly).

    Minor thing I noticed Hoborg - you haven't actually added ffdshow DXVA as an external filter to MPC-HC in this pack, only ffdshow. So if you test with MPC-HC, everything plays with ffdshow.

    I assume the advantage of reclock over the built in dynamic refresh rate changer is that if you don't have a screen that can do 24p, you can still acheive smooth playback on 24p sources? If so, +1 for reclock integration.

    Yes, i already fixed it

    Yes, exactly.

    If anyone likes the James Bond styled speedy chases then I see no issue on such huge (approx 20%) speed up in the playback speed. Majority of people wont accept such. Only 23.xxx to 24 or 25 is small enough not to cause physics to see too unnatural.

    I was surprised it works even for LiveTV (if configured correctly).

    Quite hard to see how it could work in even theory. There are two things that make it impossible:

    1) Channel changes are confusing ReClock's internal timestamp patching, this can be seen on huge delays on some channel changes or really juddering picture.
    2) Speeding up the real time sources is no possible even on theory. Just think what are the possibilities for ReClock to change the speed what broadcaster is sending the data (this makes it impossible to use ReClock for any rate matching in live tv)

    If ReClock gets added to SAF, my advice would be that it wont be used for live tv (you can assign the audio renderer per player basis in MP).
