Software Update: Reclock 1.2

Anonymous: 43710 felt inspiration coming and sent us the following text: “Reclock DirectShow Ffilter prevents jerking when playing video files in Windows. In addition, the filter can amplify the sound (gain). The changelog is on the front page; it is a big list of improvements:”

Changelog and download:

• 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 DVDs 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)

Known problems and issues:

• ReClock may not correct the good video clock for videocards with dual head capabilities or 2 RAMDACS (Matrox, GeForce4 MX, …). If you have such a card, please read the readme for instructions
• On Windows 98, ReClock cannot always see that you change resolution of activate/desactivate TV-out while a video is playing. It’s safer to quit your player before to do that, and relaunch it after.
• Graphedit cannot save a graph with ReClock when ReClock is selected as active reference clock
• Morgan Stream Switcher does not work with ReClock (won’t load if ReClock is used)
• Vsync correction will not activate when playback of DVD use DXVA mode

Planned evolutions :

• Internal audio stream switcher
• Kernel mode streaming (if i can find a better sound resampler before)
