List of Chromium Command Line Switches « Peter Beverloo. Condition. Explanation- - ⊗Report pseudo allocation traces. Pseudo traces are derived from currently active trace events. It has been observed that when file reads are consistent for 3 process launches with the same /prefetch: # argument, the Windows prefetcher starts issuing reads in batch at process launch. Because reads depend on the process type, the prefetcher wouldn't be able to observe consistent reads if no /prefetch: # arguments were used. Note that the browser process has no /prefetch: # argument; as such all other processes must have one in order to avoid polluting its profile. Note: # must always be in [1, 8]; otherwise it is ignored by the Windows prefetcher. No description↪- -/prefetch: 3[1]⊗No description↪- -/prefetch: 4[1]⊗No description↪- -/prefetch: 5[1]⊗/prefetch: # arguments for the browser process launched in background mode and for the watcher process. Use profiles 5, 6 and 7 as documented on k. Prefetch. Argument* in content_switches. No description↪- -/prefetch: 8[1]⊗Prefetch arguments are used by the Windows prefetcher to disambiguate different execution modes (i. Legal values are integers in the range [1, 8]. We reserve 8 to mean "whatever", and this will ultimately lead to processes with /prefetch: 8 having inconsistent behavior thus disabling prefetch in practice. TODO(rockot): Make it possible for embedders to override this argument on a per- service basis. Value of the - -profiler- timing flag that will disable timing information for chrome: //profiler. No description↪- -accept- resource- provider ⊗Flag indicating that a resource provider must be set up to provide cast receiver with resources. Apps cannot start until provided resources. This flag implies - -alsa- check- close- timeout=0. Command line flag for enabling account consistency. Default mode is disabled. Flagship ZDNet weblog, covering a broad range of technology news. Mirror is a legacy mode in which Google accounts are always addded to Chrome, and Chrome then adds them to the Google authentication cookies. Dice is a new experiment in which Chrome is aware of the accounts in the Google authentication cookies. No description↪- -aec- refined- adaptive- filter ⊗Enables a new tuning of the Web. RTC Acoustic Echo Canceler (AEC). The new tuning aims at resolving two issues with the AEC: https: //bugs. ![]() TODO(hlundin): Remove this switch when experimentation is over; crbug. Override the default minimum starting volume of the Automatic Gain Control algorithm in Web. RTC used with audio tracks from get. User. Media. The valid range is 1. Values outside that range will be clamped to the lowest or highest valid value inside Web. RTC. TODO(tommi): Remove this switch when crbug. No description↪- -aggressive- cache- discard ⊗No description↪- -aggressive- tab- discard ⊗No description↪- -all[3]⊗No description↪- -allarticles ⊗No description↪- -allow- cross- origin- auth- prompt ⊗Allows third- party content included on a page to prompt for a HTTP basic auth username/password pair. Allow access to external pages during layout tests. If this flag is passed, failed policy fetches will not cause profile initialization to fail. This is useful for tests because it means that tests don't have to mock out the policy infrastructure. By default, file: // URIs cannot read other file: // URIs. This is an override for developers who need the old behavior for testing. Allows media playback for hidden Web. Contents ↪- -allow- http- background- page ⊗Allows non- https URL for background_page for hosted apps. Allow non- secure origins to use the screen capture API and the desktop. Capture extension API. Enables TLS/SSL errors on localhost to be ignored (no interstitial, no blocking of requests). Allows the browser to load extensions that lack a modern manifest when that would otherwise be forbidden. Adobe Reader No Printer Installed Citrix Login Remote![]() Allows loopback interface to be added in network list for peer connection. Specifies comma- separated list of extension ids or hosts to grant access to CRX file system APIs. Specifies comma- separated list of extension ids or hosts to grant access to file handle APIs. Specifies comma- separated list of extension ids or hosts to grant access to TCP/UDP socket APIs. Enables the sandboxed processes to run without a job object assigned to them. This flag is required to allow Chrome to run in Remote. Apps or Citrix. This flag can reduce the security of the sandboxed processes and allow them to do certain API calls like shut down Windows or access the clipboard.
Also we lose the chance to kill some processes until the outer job that owns them finishes. Don't block outdated plugins. Allows remote attestation (RA) in dev mode for testing purpose. Usually RA is disabled in dev mode because it will always fail. However, there are cases in testing where we do want to go through the permission flow even in dev mode. This can be enabled by this flag. By default, an https page cannot run Java. Script, CSS or plugins from http URLs. This provides an override to get the old insecure behavior. Allows debugging of sandboxed processes (see zygote_main_linux. Allows Web Push notifications that do not show a notification. Time in ms to wait before closing the PCM handle when no more mixer inputs remain. Assumed to be 0 if - -accept- resource- provider is present. Flag that enables resampling audio with sample rate below 3. Hz up to 4. 8k. Hz. Should be set to true for internal audio products. Optional flag to set a fixed sample rate for the alsa device. The Alsa device to use when opening an audio input stream. Name of the device the mute mixer should be opened on. If this flag is not specified it will default to the same device as k. Alsa. Volume. Device. Name. ↪- -alsa- mute- element- name ⊗Name of the simple mixer control element that the ALSA- based media library should use to mute the system. Minimum number of available frames for scheduling a transfer. Size of the ALSA output buffer in frames. This directly sets the latency of the output device. Latency can be calculated by multiplying the sample rate by the output buffer size. The Alsa device to use when opening an audio stream. Size of the ALSA output period in frames. The period of an ALSA output device determines how many frames elapse between hardware interrupts. How many frames need to be in the output buffer before output starts. Name of the device the volume control mixer should be opened on. Will use the same device as k. Alsa. Output. Device and fall back to "default" if k. Alsa. Output. Device is not supplied. Name of the simple mixer control element that the ALSA- based media library should use to control the volume. Also emit full event trace logs for successful tests. The Chrome- Proxy "exp" directive value used by data reduction proxy to receive an alternative back end implementation. Prevents Chrome from requiring authorization to run certain widely installed but less commonly used plugins. No description↪- -always- use- complex- text ⊗Always use the complex text path for layout tests. No description↪- -android- fonts- path ⊗Uses the android Sk. Font. Manager on linux. The specified directory should include the configuration xml file with the name "fonts. This is used in blimp to emulate android fonts on linux. Redirect stderr to the given port. Only supported on Android. Redirect stdin to the given port. Only supported on Android. Redirect stdout to the given port. Only supported on Android. No description↪- -app ⊗Specifies that the associated value should be launched in "application" mode. Specifies whether an app launched in kiosk mode was auto launched with zero delay. Used in order to properly restore auto- launched state during session restore flow. Specifies that the extension- app with the specified id should be launched according to its configuration. Value of GAIA auth code for - -force- app- mode. Value of OAuth. 2 refresh token for - -force- app- mode. Path for app's OEM manifest file. Allow roaming in the cellular network. Size for the host window to create (i. SSID of the preferred Wi. Fi network. ↪- -app- shell- refresh- token ⊗Refresh token for identity API calls for the current user. Used for testing. User email address of the current user. No description↪- -apps- gallery- download- url ⊗The URL that the webstore APIs download extensions from. Note: the URL must contain one '%s' for the extension ID. The update url used by gallery/webstore extensions. The URL to use for the gallery link in the app launcher. Prevents Chrome from quitting when Chrome Apps are open. Signals ARC support status on this device.
