Clean up code added during merge
Corrects the SC player script URL by removing a duplicated version prefix. mmpVersion already contains v, resulting in vv2.x.x/main.js → 404. Updated to v2.x.x/main.js so main.js loads properly.
Updates Stripchat JS chunk detection to match the new hashed chunk naming. Replaces the hard-coded Doppio lookup with a hash-based pattern so getInitialData() can locate the correct chunk and initialize properly again.
Fixes a regression in SC HLS playlist handling. Ensures playlist parameters are correctly applied to variant URLs, restoring proper segment resolution and ffmpeg startup behavior.
Adds support for Mouflon v2 (psch=v2) HLS playlists on SC. Implements URI-based segment decoding, including reversed encrypted segments and EXT-X-MAP init handling, while preserving existing Mouflon v1 FILE-based logic.
Added updated decryption keys to fix promotional video download issue. Changes: - Added two new decryption keys - Kept existing key for backward compatibility
SC decided to rename their api fields nd broke everything lol changed `features` → `featureSettings` so it actually works now tested: doesn't crash anymore
img.doppiocdn.com is dead for the player assets, they quietly moved everything to mmp.doppiocdn.com. Same version, different subdomain. - hardcoded origin was pointing to the old img. subdomain → 404 on main.js - updated MMPExternalSourceOrigin to mmp.doppiocdn.com one line fix, took longer to debug than to patch lol
…MMP player version from homepage
## Problem
Stripchat removed both `featuresV2` and `mmpVersion` from their static
config API (`/api/front/v3/config/static`). This caused a hard crash on
startup with:
Exception: 'featuresV2' not found. Available keys: [...]
## Root Cause
`getInitialData()` relied on `static_data["featuresV2"]["playerModuleExternalLoading"]["mmpVersion"]`
to build the MMP player base URL. That entire key hierarchy no longer
exists in the API response.
## Solution
- Read `mmp_origin` from `featureSettings.MMPExternalUnitedSourceOrigin`
(still present in the API), with a known-good CDN URL as default.
- Auto-detect `mmp_version` by scraping the stripchat.com homepage for
the MMP script src URL pattern. Falls back to a hardcoded constant
`_MMP_FALLBACK_VERSION = "v2.6.0"` if scraping fails (e.g. rate limit,
geo-block).
- Added `_MMP_FALLBACK_VERSION` class constant for easy manual updates
when the player version changes in future.
## Files Changed
- `streamonitor/sites/stripchat.py`
## Testing
Verified the static config API response no longer contains `featuresV2`
or `mmpVersion`. Confirmed `v2.6.0` is the current MMP version via
DevTools network inspection on stripchat.com.

Performance Improvements
Added LRU caching for frequently computed operations:
Pre-compiled regex patterns at class level instead of compiling on every use
Optimized string operations:
Improved network handling:
Better memory usage:
Robustness Improvements
Multiple fallback patterns for finding doppio.js file:
require()pattern and new chunk-based patternAutomatic proxy support from environment variables (HTTP_PROXY, HTTPS_PROXY)
