Detailed Description

Here are some suggestions for TODO tasks...

NEXT:

• For pause-then-playbackshifted code...
  • can't write frames once pGetFrame is created.
  • write our own compressor/decompressor?
  • use no compression for now with AVIStreamRead() instead of getframe?
  • actually, it works right now, but the file it creates is a corrupt AVI.

LATER:

• Add a 'Preferred Pixelwidth While Recording' edit as an option.
• in options dialog, add waveform buffer count and size (advanced section).
• enumerate saved avi file dynamic radio checked menu items.
• make sure that if m_mode is STOPPED, memory & resource usage is minimized.
• Remove 4GB filesize limitation. Maybe try stop then immeditate rerecord.
• BUG: During playback in windowed mode, writing too wide of lines.
• TWEAK: You can see the live feed peek in between clips during play mode.
• Add slowforward/backward feature.
• Play audio (option) during fastforward/backward.
• Implement full height recording option.
• Use the standard DScaler Settings for ini file stuff?
• Use -height for right-side-up AVI? Matches odd/even field orientation.

OPTIMIZE:

• Is there a codec out there that takes YUY2, compress it, but don't convert to RGB in the process? If so, we can get rid of our rgb<-->yuv routines.

DOC:

• Must setup Audio Mixer through its dialog. You can then uncheck the box if you don't normally use it, but all the dropdowns should point to the input on your audio card that your capture card's audio is attached to.
• For speed, video clips are saved at 1/2 height. Perhaps future versions can be optimized to handle full-height recording.
• pixel width affects DF/S. Choose a low enough pixel width for 0 DF/S.
• Currently, If you record with audio at, say, 44.1kHz, etc, make sure you have these same settings on playback.

LATEST CHANGES:

• Solidified the auto-pixelwidth-setting feature for AVIs of varying width.
• Added preliminary pause feature. Left it disabled since it's unstable.
• Added use of mixerdev to mute, but still record audio during pause/shifting.
• Made public static function pointers to the mmx/c yuv<->rgb converters.
• Disabled all height control features. They made pause/shifting difficult.

Member Function Documentation

bool CTimeShift::OnDestroy (  void   )  [static]

There is no public "create" method, it's created the first time you record, popup options, etc. Call Destroy() as often as you want to assure that all timeshift resources are freed.
