Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
LruClockCache
- Is 180 million lookups per second performance ok for an asynchronous cache written in C++ running on FX8150? (has cache-coherence and runs only 1 consumer thread as back-end)

Is Python Interpreter optimized enough for low-latency caching algorithm?
Is it feasible to write a fast caching library for Python in pure Python codes or does its function calling overhead limit the performance of cache access? What about linking a C++ caching function to Python environment to be called? Does it cause worse latency or better latency than the pure-Python version? (I'm considering converting my C++ caching tool to Python: https://github.com/tugrul512bit/LruClockCache which has performance between 50M - 2B lookups per second depending on use-cases)
- 2D Direct Mapped Cache Is Much Better Than Normal Direct Mapped Cache In 2D Access Patterns
- What is the absolute fastest way of using mmap for read-only random-access pattern?

Does C++ have a feature like optionally producing same pointer value from allocation with help of an integer key?
Hi, I implemented a multi-level LRU+direct mapped cache (https://github.com/tugrul512bit/LruClockCache/wiki/How-To-Do-Multithreading-With-a-Read-Only-Multi-Level-Cache) and it works as a single threaded read-write cache or multi-threaded read-only cache. Now I'm going to add cache-coherence to it (so it will be read-write multithreaded) but by using smart pointers as "value" cells. So, a get method will return shared_ptr and I can change its data by dereferencing and it instantly visible on other L1 caches in other threads. But there are some problems.
- Multi-Level Cache (Direct Mapped L1 + LRU approx L2 + guard_locked LRU LLC) does up to 400 million lookups per second in Gaussian Blur operation on FX8150 CPU.
-
Is 20 million lookups per second performance ok for a single threaded LRU cache written in C++? (CPU is fx8150 3.6GHz)
Implementation: https://github.com/tugrul512bit/LruClockCache/blob/main/LruClockCache.h

Mobile SRT stability
Is receiver side also using mobile internet? You could try to setup this on separate server and both sender and receiver connnect to it. https://github.com/Haivision/srt/blob/master/docs/apps/srt-live-transmit.md

Nginx + SRT streaming - I need a push in the right direction
Here is one example how to feed SRT stream to ffmpeg. Try streaming directly to this via OBS first and confirm it works before stacking more software between endpoints. https://github.com/Haivision/srt/issues/506

4 Different ways to Broadcast SRT Streams
SRT, or Secure Reliable Transport, is a type of streaming protocol that provides enhanced security and reliability for video streaming. SRT is becoming increasingly popular among broadcasters and streamers including industry stalwarts such as ESPN because of its ability to deliver high-quality content over challenging network conditions and for its ability to make contribution and stream ingestion easy. SRT streams provide improved security, low latency, and flexibility and is supported by a global community of developers all contributing to the open-source project. Because of the power of SRT streams, Dolby.io Real-Time Streaming has decided to launch support with an SRT open beta program.

SRT Streaming failing when adding audio
If it turns out to be an SRT/socket issue (rather than an audio issue) you can pump FFmpeg into https://github.com/Haivision/srt srt-live-transmit, and let that do the SRT. It is a very long time since I played with srt-live-transmit, but it did behave differently to both FFmpeg and TSDuck's SRT impementations when there were input issues. Obviously, putting more components in the chain may be disadvantageous, but component abstraction can help when debugging.

Video Streaming Protocols: What Are They & How to Choose The Best One
SRT is an open-source protocol developed by streaming technology provider Haivision. Known for its security, reliability, compatibility, and low-latency streaming it is the preferred protocol for members of the SRT Alliance. This protocol does not rely on a single codec, which allows developers to pair it with any audio and video codecs they desire.

Options for multicasting or streaming using AV1?
I've also looked at SRT, which to all intents and purposes ought to work, but doesn't?
