Is there a reason that the default ripping directory needs to change?
This would create a breaking change for users which rely on the default config file (especially those using Docker or a unix-like environment)

I just did a fresh install of HandBrake (Windows 11, 64bit) the default install path was 'C:\Program Files\HandBrake', but there's no HandBrakeCLI.exe file, just 'HandBrake.exe' and 'HandBrake.Worker.exe'.
I'm not super familiar with the CLI for HandBrake; which of these should AutoRip be using?

I asked AI to update the documentation for the HandbrakeCLI (which is a separate install). Does it work better now?

Thanks for the work on this @johnml1135! I left comments on a few specific areas of your changes.
Additionally, how would this work for users using MakeMKV-Auto-Rip via Docker? So far, the goal has been to maintain feature parity between the Docker distribution and other installations. I'd prefer to maintain that if you're willing to contribute the energy to solving that issue. Alternatively, we should at least call it out in the README and other documentation until myself or someone else has time to implement it.
Similar to my Docker comment, the web interface should also be updated so that the new HandBrake configuration options can be modified from the existing configuration menus too.
P.S. It looks like code coverage dropped a bit below the 80% target with this PR as well.

I don't think this retry code is getting called anywhere. I'm fairly sure that conversion would fail to retry if a situation that required a retry occurred.
I'm a little on the fence for how necessary it is to have a retry ability in the first place for something like this. I wonder what situations would cause HandBrake to fail at first, but succeed when ran a second time.
But overall, a good addition as long as it's properly implemented.

I don't know either - would you like me to rip it out? AI added it.

I don't see the 'HANDBRAKE_STRICT_VALIDATION' var used anywhere in the code, what is this supposed to accomplish?

A few things I noticed about the HandBrake argument handling
Issues:
- Silent failure (warning only) means users won't know their args were ignored
- The regex doesn't catch all dangerous patterns (e.g., >, <, \n, etc.)
Recommendation:
- Throw an error instead of just warning
- Use child_process.spawn with array arguments instead of exec with a shell string

Why remove the object freeze logic from this? Originally I had added this to help prevent accidentally mutating our constants in the app logic.

We should do something similar to how we report a success/failure array for ripping discs for when HandBrake processing passes/fails, so that users have good visibility into the status of each disc.

I don't fully know what you are asking for here.

I can try to make a few of these fixes - but honestly, I am experienced as a C# and python developer, but not with JS. I had copilot do 99% of it. I can make more changes, but it would be merely instructing Copilot to do it and I don't know if it is doing something wrong (without more effort than I am able to put in right now). |
- Reverted movie_rips_dir to ./media (no breaking change) - Disabled HandBrake by default in config.yaml - Updated HandBrakeCLI documentation - clarified it's a SEPARATE download from GUI * Added direct links to CLI download page (downloads2.php) * Noted Windows CLI comes as ZIP file, not installer * Updated example paths to reflect user's extraction location - Restored Object.freeze() on all constants to prevent mutation - Enhanced argument validation to throw errors (not just warn) for unsafe characters - Improved dangerous character regex to catch more patterns (>&<\n\r) - Implemented retry logic - now properly called on conversion failures * Automatic fallback to simpler presets on failure * Original MKV always preserved on failure - Added HandBrake success/failure tracking arrays * goodHandBrakeArray and badHandBrakeArray similar to disc ripping * Results displayed in displayResults() method - Removed unused HANDBRAKE_STRICT_VALIDATION environment variable from docs - Updated integration test to expect new error-throwing behavior All 433 tests passing

Comment generated from AI: Thank you @Poisonite for the detailed code review! I've used GitHub Copilot to implement all the primary fixes you requested: ✅ Implemented Fixes: ✅ Reverted movie_rips_dir back to "./media" ✅ Clarified HandBrakeCLI is a SEPARATE download from the GUI (different installer/package) ✅ Retry code is now properly called in the convertFile catch block ✅ Deleted HANDBRAKE_STRICT_VALIDATION documentation since it wasn't implemented ✅ Changed from warning to throwing an error for unsafe additional arguments ✅ Re-added Object.freeze() to VALIDATION_CONSTANTS, HANDBRAKE_CONSTANTS, and all nested objects ✅ Added goodHandBrakeArray and badHandBrakeArray tracking |

@Poisonite - I (that is, GPT-5) also added a bunch of tests to increase code coverage. Here is what GPT-5-Codex said when reviewing the added tests: Quick recap of what’s new
Sanity check on the testsEverything looks consistent with the production code:

@Poisonite - Is there anything else you would like me (that is, GPT-5) to do? |

Hi @johnml1135 I'll take a look this weekend, sorry I haven't gotten back to you sooner. Super busy week for me haha |
|
No, rush - honestly I just made the updates for myself and I can use them as-is. I hope others can benefit from the work as well. |
- Consolidate duplicate validation: Use validateHandBrakeConfig() from handbrake-config.js in AppConfig.validate() instead of duplicating logic - Convert sync file operations to async: Replace fs.existsSync/statSync/openSync/readSync with fs/promises in validateOutput() - Add log verbosity control: Add Logger.debug() method and verbose mode toggle to reduce console noise - Convert verbose logging to debug: Change ~30 Logger.info() calls to Logger.debug() for detailed output - Add tests for Logger: Add 8 new tests for debug() and setVerbose()/isVerbose() methods - Update handbrake.service tests: Fix mocks for new async fs/promises implementation Coverage: 80.77% overall (473 tests passing)
