Optimize stripchat.py performance with caching & improved request handling by medi0x1 · Pull Request #268 · lossless1024/StreaMonitor

medi0x1 · 2025-11-29T16:22:40Z

Summary

This PR optimizes stripchat.py implementation to improve performance & reduce resource usage. The changes focus on reducing redundant computations, improving network efficiency, nd adding better fallback mechanisms.

Changes

Performance Improvements

Added LRU caching for frequently computed operations:
- Hash computations (SHA256)
- Key extractions from doppio.js
- M3U8 decoding operations
Pre-compiled regex patterns at class level instead of compiling on every use
Optimized string operations:
- Using list append + join instead of string concatenation
- Direct string search for simple patterns instead of regex
Improved network handling:
- Connection pooling for reusing HTTP connections
- Enabled gzip compression for API responses
- Reduced timeouts for faster error handling
Better memory usage:
- Using frozenset for status lookups (faster than lists)
- Reduced unnecessary object allocations

Robustness Improvements

Multiple fallback patterns for finding doppio.js file:
- Handles both old require() pattern and new chunk-based pattern
- Compatible with changes from PR Attempt at workaround for broken stripchat #263
Automatic proxy support from environment variables (HTTP_PROXY, HTTPS_PROXY)
Improved error handling with proper exception catching

Code Quality

Added type hints for better code clarity
Cleaned up unnecessary debug statements
More consistent code style

Performance Impact

Testing shows significant improvements:

Initial data fetching: ~3-5x faster
M3U8 decoding: ~5-10x faster
Status checks: ~2-3x faster
Overall responsiveness: Much improved

Compatibility

Fully backwards compatible
No breaking changes to existing functionality
Works with existing configurations
No new dependencies required

Testing

Tested with live StripChat streams
Verified proxy support (SOCKS5)
Compatible with both old and new StripChat JavaScript structures
No issues found during testing

how to solve this ??

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.

how to solve this ??

You can fix the issue by removing the extra v since mmpVersion already contains it:

- mmp_base = f"{mmp_origin}/v{mmp_version}"
+ mmp_base = f"{mmp_origin}/{mmp_version}"

This corrects vv2.x.x → v2.x.x and resolves the 404.
PR is now updated nd the problem is fixed if you want to pull the latest changes.

Error while trying to add a model from SCVR

2025-12-15 23:54:36,854 - INFO - manager_cli: Failed to add: StripChat.init() takes 2 positional arguments but 3 were given

Same error from both cli and web frontend.

Fixed by removing the roomid artifact in the stripchat_vr.py file and using the same as in your version of stripchat.py

def init(self, username):
super().init(username)

instead of

def init(self, username, room_id=None):
super().init(username, room_id)

any idea how to fix? Thanks!

Maybe

#_DOPPIO_INDEX_PATTERN = re.compile(r'([0-9]+):"Doppio"')
_DOPPIO_INDEX_PATTERN = re.compile(r'(\d+):\s*"([a-f0-9]+)"')

#doppio_url = f"{mmp_base}/chunk-Doppio-{hash_match[1]}.js"
doppio_url = f"{mmp_base}/chunk-{hash_match[1]}.js"

It works correctly. Thanks

medi0x1 · 2025-12-19T19:16:41Z

Just to keep scope tight: this PR only touches stripchat.py.
No VR code, no stripchat_vr.py, no resolution/FPS changes.

If VR stuff is breaking, that’s a separate issue.
Test this PR on a clean clone with only the files changed here .

Zivlosos · 2025-12-19T20:22:05Z

For the record, I do not experience the resolution or fps issue with VR on my end after making the necessary changes to fix stripchat based medi0x1's build and the additional fix I provided for stripchat vr file.

Seems indeed unrelated.

Interesting, sorry i thought sc and scvr was intertwined.
So you dont get low resolution? I downloaded a fresh PR from the last of medi0x1's build. I will try again then.
Ty for the information.

Kurosaki22 · 2025-12-23T16:26:52Z

seems like they just changed something again.
Directly after the record starts it gets ended.
It will then start the record again which gets directly ended again.
This repeats to infinity

#params = f"{'&' if '?' in variants[0]['url'] else '?'}psch={psch}&pkey={pkey}"
params = f"{'&' if '?' in variants[0]['url'] else '?'}psch=v1&pkey={pkey}"

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.

works for me again

CorleoneAlCapone · 2025-12-31T13:26:54Z

Aweseome work man, StripChat itself works perfectly again!

But to get StripChat-VR working it still needs a small fix inside stripchat_vr.py like already mentioned earlier in this post by someone else.

From:

    def __init__(self, username, room_id=None):
        super().__init__(username, room_id)

To:

    def __init__(self, username):
        super().__init__(username)

medi0x1 · 2025-12-31T13:40:52Z

Appreciate the confirmation. This PR is limited to stripchat.py; VR is a separate topic.

If I remove every SC model the Downloader runs again and if I try to add a SC model I get "Failed to add features" error

SC decided to rename their api fields nd broke everything lol changed `features` → `featureSettings` so it actually works now tested: doesn't crash anymore

updated, test if it works on ur side.

Works perfectly again :) Thanks

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

RikaCelery · 2026-03-07T10:56:03Z

Hardcoding _mouflon_keys may not be a good idea.
