10/10/2003 - Version 1.2 available. Changelog:
- changed the way media frame rate detection work. It can use DirectShow builtin methods (like before), or internal methods based on frame presentation to the video renderer (as DirectShow is not always accurate). Internal methods being based on the VSync monitor, it is now enabled and can not be disabled. I will not use the term "Vsync monitor" anymore, but "Vsync correction" for the part of it that control the frame presentation to the video renderer. See config app and readme for details
- features that are provided by the formet VSync monitor are disabled on Win9x, until i find why they crash on this OS. So you won't have DVD frame rate detection or VSync correction on win9x systems
- VSync correction can now be enabled/disabled separately for VMR9 and other video renderers (as VMR9 has some sort of identical mechanism that can fight against ReClock). See config app
- added support for audio cards (like Vortex2) that don't support new WaveFormatExtensible multichannel audio format. See "accept old multichannel formats" in config app
- ReClock can now be loaded in place of the default DirectSound/WaveOut Microsoft audio renderers, even if the application request to load one of those. This allow more players to use ReClock even if they don't want to (like Windows Media Player for DVD, or Windows Media Center Edition). Be careful with this option because it will tweak the registry, so you'd better use it only on a dedicated PC. See config app to enable this feature. Also i had to remove the Enable/Disable ReClock quick access menus that are incompatible with this modification
- properties panel now give informations about video size and format
- hopefully fixed audio dropouts that could occur when starting playback especially with DVD
- fixed a random and nasty freezing problem that would happen when playing a DVD (especially a NTSC DVD). As a consequence, frame rate detection for PAL & NTSC DVD's is now based on internal methods only, so DXVA will be a problem if you use it
- fixed another even more ugly freezing problem that could randomly happen just after starting playback (especially with a DVD)
- fixed a bug that was causing garbled sound in PCM IEEE float format (especially with .ogm files and also with AC3Filter)
- fixed DVD default frame rate entered in config app that was not working since version 1.1
- fixed unwanted sound skips or pauses that could happen during playback while switching between different frame rates that were compatible with the current refresh rate (for example between 23.976 and 29.970 during NTSC DVD playback at 120hz)
- added more media speed settings
- updated the readme with new informations (worth reading)

Implementation of the ReClock filter code.
Should enable better NTSC <=> PAL handeling for all =)))
Still have problems playing NTSC media files on PAL Xbox/TV, + heard of people with Xbox/TV's problem playing PAL files.
Could source code from the ReClock DirectShow Filter to add an optional filter for this? (enable/disable from under settings).
ReClock can use either Direct3D or DirectDraw so that's good, I understand the Xbox requires and uses Direct3D as the API).
Currenly the latest version if 1.1 and it's open source (GPL). http://ogo.nerim.net/reclockfilter OGO (ogo@nerim.net) the programmer updates it quite often.
Just hope this does not cause problems with BivX media files.
In addition ReClock has audio renderer with hardware or software rate adaptation in real-time and dynamic range compression capabilities which could be used as adititonal filters, but that's a complete different story.
ReClock: Description: The purpose of ReClock is to definitely get rid of jerky playback of AVI and MPEG material on a PC (or a PC connected to a TV). It's a DirectShow filter which is loaded in place of the default directsound audio renderer. It provides a new reference clock that is locked to the video card hardware clock, in order to ensure that frames are played at the exact speed of what is expected by the video card vertical sync. It also provides a frame rate adaptator for media files that do not match a multiple of the video card refresh rate (ex: playback of 23,976fps IVTC NTSC on a PAL TV). For a full description of ReClock, please read carefully the README file in the distribution.
Maybe also can use code from BeSweet (an open source audio transcoder) http://dspguru.doom9.net/
BeSweet process is done with floating-point arithmethics, reaching high-quality encodes. No intermediate, temporary, files are being created by BeSweet while running. saving precious disk space.
