- TAKSI manual v0.5.1-dev December 08, 2004
- ==============================================================================
-
-
- 0. About:
- ---------
- Taksi is a screenshot/video-capture program for 3D applications (games, and
- etc.) Currently, it works with DirectX 8, DirectX 9, and OpenGL applications.
- (Support for older DirectX interfaces may be implemented in the future)
- Taksi is free software.
-
-
- 1. Current state / What's new:
- ------------------------------
- BETA. DirectX 8 / DirectX 9 / OpenGL support implemented.
- This is a "bug-fixing/internal enhancements" release. Changes made include:
-
- New in 0.5.1-dev:
- Early experiments with using codec to write compressed video while
- capturing it. Works somewhat (at least with some codecs), but still a lot
- of details to figure out and implement properly.
-
-
- 2. Supported operating systems:
- -------------------------------
- Windows 95, Windows 98, Windows ME,
- Windows NT 4.0, Windows 2000, Windows XP.
-
-
- 3. Capture specifications:
- --------------------------
- Screenshot format: 24 bit BMP files.
- Video: compressed or uncompressed AVI-files (no audio).
-
-
- 4. Games/Apps tested with:
- --------------------------
- Direct3D 8:
- Pro Evolution Soccer 3, Winning Eleven 7 International,
- F1 2001, FIFA 2003, WarCraft III.
- Unreal Tournament 2003, Unreal Tournament 2004,
- 3DMark2001 SE.
- Direct3D 9:
- Prince of Persia: Sands of Time,
- Leisure Suit Larry: Magna Cum Laude,
- 3DMark03.
- OpenGL:
- DOOM 3, Return To Castle Wolfenstein (demo),
- Tennis Critters (demo), PyOpenGL bindings.
-
-
- 5. Usage:
- ---------
-
- STEP 1. Run taksi.exe
- STEP 2. Run a game that uses one of the supported APIs (DX8, DX9 or OpenGL)
- (The order of these two steps is not important for taksi. It should be
- able to hook on the game in either case.)
-
- STEP 3. Look at left top corner of the screen.
- If you see a green rectangle in there, then Taksi was able
- to sucessfully hook on the game.
-
-
- 6. Default keys:
- ----------------
-
- F5: Turn visual indicator ON/OFF.
- F6: Toggle system-wide hook mode. When ON (indicator turns blue), allows
- for mapping into multiple applications, but may have a strong negative
- effect on the overall performance of the system. Recommended state: OFF.
- (The hot-key is disabled, when Taksi uses DirectInput for keyboard
- handling.)
- F7: Small screenshot (WIDTH/2 x HEIGHT/2).
- F8: Regular screenshot (WIDTH x HEIGHT).
- ScrollLock: Video capture ON/OFF (Writes an uncompressed AVI-file).
- (Dimensions of the video are WIDTH/2 x HEIGHT/2.)
-
-
- 7. IMPORTANT DISK SPACE CONSIDERATIONS:
- ---------------------------------------
- Taksi writes uncompressed AVI files. Basically, this means you need a lot
- of free disk space. (Once captured, the AVI-files can be compressed into
- much smaller files, using the tools like an excellent free software
- program, called VirtualDub by Avery Lee.) However, at the time of
- capture, for performance reasons, no compression is done, which means that
- video files grow large very fast.
-
- There is no time limit in the video capture mode, so the only constraint
- is the available disk space. Keep this in mind, when setting the directory
- for you captured videos.
-
-
- 8. Configuration:
- -----------------
- Taksi uses configuration file, called "taksi.INI". It is optional, so the
- program can operate without it, using built-in default settings.
- The configuration file is managed automatically by Taksi (it is read
- on start-up, and updated when "Save And Apply" button is clicked.).
- However, it can be edited manually as well.
-
- The following options exist:
-
- 1) Basic capture options:
- =========================
-
- Capture directory ("CaptureDir"):
- This is the directory, where your screenshots and video will be stored.
- IMPORTANT: This directory must exist before any capture is attempted.
-
- Target frame rate ("MovieFrameRateTarget"):
- Desired frame rate of the captured video. So-called "Adaptive" algorithm
- uses this setting. When Adaptive algorithm is used, Taksi will try to
- capture the video that will run at specified frame rate, and appear to
- be of the same speed as the actual game.
- NOTE: This doesn't always work well. It seems to work fine for applications
- with high frame rate, but often poorly for low frame rate apps. This
- Adaptive algorithm is still work-in-progress, so hopefully, i'll be able
- to improve it.
- If it fails to deliver decent videos, try using "Custom settings", which
- are described below.
-
- 2) Hot-key mappings:
- ====================
- Define keys that trigger the actions: screen shot capture, video capture,
- indicator appear/disappear, global hook mode.
-
- NOTE: Sometimes, the hot-keys may be slow to respond, or not-responsive
- at all. First thing to try is to re-assign the hot-keys as they may clash
- with some other actions in the game that are triggered by these keys.
- If that doesn't help, try changing the value for "useDirectInput"
- configuration option, described in the next section.
-
- 3) Advanced options:
- ====================
- These options you may never need to change.
- That said, there are certainly use cases, when you might want (or need)
- to modify them.
-
- "startup.hookMode.systemWide" : 0/1
- Takes boolean values, where 0 - means that taksi should go into
- "exclusive" mode once an application is hooked, effectively meaning that
- no other application will be hooked until this application exits, or
- taksi exits and unhooks from it. 1 - means stay in system wide mode,
- allowing many apps to be hooked in parallel. Typically, you would
- want Taksi to go to exclusive mode as soon as possible, because
- system-wide mode requires extra message processing by the OS, and
- may slow down the whole system. However, system-wide mode is useful
- when you want to run many windowed apps at the same time and hook them
- all with Taksi. (Remember that HOOK_MODE hot-key can still be used from
- any of those applications to switch back-and-forth between the modes)
- Recommended default: 0
-
- "keyboard.useDirectInput" : 0/1
- Takes boolean values. Allows to pick one of two methods of handling
- hot-keys: either through a keyboard hook procedure (value 0), or by
- using DirectInput interface from DirectX 8 API (value 1). Typically
- you would want to use DirectInput, because it allows to correctly
- handle hot-keys across wider range of applications. In fact, for
- some apps (like 3DMark2001 SE), using DirectInput may be the only way
- to capture hot-key toggles. Using keyboard hook can be a better
- alternative when you want to hook multiple applications at the same
- time (i.e. "system-wide" mode), and want to send hot-key commands
- separately to each application: in other words, the one with
- keyboard focus will receive the hot-key toggles, but others will not.
- (When DirectInput is used, all hooked apps will receive and process
- the hot-key events simultaneously, which may not be desirable).
- Recommended default: 1
-
- "movie.fullSize" : 0/1
- Takes boolean values. Allows to capture video in either "half-size"
- mode, when frames are reduced by half in each dimension, or in
- "full-size" mode, when frames are kept as they are in the game.
- Warning: performance issues exist with full-size video capture, if
- used in high-resolution modes (1024x768 and higher). Use it only
- if you really need to, and you have a very fast graphics card, and
- you have tons of hard drive space.
- Recommended default: 0
-
- NOTE: There is no way to modify the values of these settings via GUI,
- so in order to make a change, you need to manually edit the config file
- (using any text editor), and then restart Taksi.
-
- 4) Custom video settings:
- =========================
- This is the alternative to Adaptive mode.
- Custom settings come in groups, with each group having a unique id.
- There are 3 settings in a group: pattern, frame rate, and frame weight.
- Pattern allows you to select which application(s) should be handled by
- this custom settings group. When taksi.dll is mapped into an application,
- it checks if any part of applications's full executable filename matches
- the pattern of any group. Usually, you can just specify the name of
- the game's main executable file, but sometimes you may wish to be more
- or less specific. Frame rate is the frame rate of captured video.
- Frame Weight specifies how much each game frame should contribute to
- captured video frame.
- Examples of weight setting:
- 1.0 - every frame of the game will be captured in the video.
- 4.0 - every frame of the game will be duplicated 4 times in the
- captured video. (You rarely would wanna use something like
- that though).
- 0.33 - approximately every 3rd frame of the game is captured in the video.
- 0.4 - 2 out of 5 frames are captured.
-
- Keep in mind that custom settings may deliver very weird results of
- either very slow or very fast videos. You may need to experiment with
- the settings. However, i found out that for some applications, good
- custom settings can deliver much better (and smaller) videos than the ones
- captured in Adaptive mode.
