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.

[mpv] openh264 on RedHat?
I've installed mpv but was unable to play any videos see this. Then I compiled and installed openh264 from github. Yet, I still have performance issues, video plays like a slide show..

Red Hat To Stop Shipping LibreOffice In Future RHEL, Limiting Fedora LO Involvement
The codecs are open source. Gstreamer. Ffmpeg. H264.

Do flatpaks have h264 hw acceleration
No, it is definitely using hardware acceleration on a number of platforms: https://github.com/cisco/openh264/tree/master/codec/encoder/core and https://github.com/cisco/openh264/tree/master/codec/decoder/core. However, the docs say it will fallback to C/C++. But I don't believe that's happening on popular platforms like x86, ARM, and Aarch64.

TikTok girl‘s hot dancing.
I found the extension but haven't been able to get it to work yet. It needs openh264 installed and I haven't been able to figure out where to put the binary for it yet, but if you figure it out let me know! Lol :D

firefox cant play h264 or 5 five videos
If you had the media.gmp.decoder.enabled pref flipped to true, I might have guessed that Firefox updated the OpenH264 plugin and downgraded it. You could try replacing the library from one at https://github.com/cisco/openh264/releases/tag/v2.3.1. Go to about:support, open your profile directory, and find the gmp-gmpopenh264/1.8.1.2 folder. Replace the binary with the one from the linked github page. Restart Firefox.
- Displaying streaming video, can it be done natively and using hardware decoding in vb.net ?
- proprietary software got installed after installing virt-manager which is opensource?
- Please restore our registers when you’re done with them

Shouldn't the free version of Resolve on Linux support mp4 natively?
Now that CISCO has released an Open Source H.264 Codec available on all major platforms what excuses does Blackmagic Design have left?

Uncommon and huge resolutions in h264
Outside of the hardware implementations, the other popular H.264 encoders are MainConcept (which I think Adobe licenses). There are a few others https://en.wikipedia.org/wiki/Advanced_Video_Coding#Software_encoders. Cisco's OpenH264 is free, but last time I checked was limited in profile support. The repo claims "Max frame size is 36864 macro-blocks".

Improve an algorithm performance step by step
I use samply to profile the Rust code. It has a nice integration with the Firefox Profiler. You can also share the profiling results with others by uploading them to the cloud. Here is an example of the C++ version profiling on GIST. The FlameGraph and CallTree are the most common views. Remember to grant the performance event permission and increase the mlock limit:
-
Long running tab (kiosk), 100% CPU
Probably your best bet is to use the Firefox Profiler once it starts hogging the CPU to try to see what it's doing. I'd be happy to take a look at the result although I don't have a lot of experience at diagnosing performance problems; hopefully the profile will make it obvious what's going on.

Slow Firefox Startup
I tried using the https://profiler.firefox.com/ and running with:

Definite tab bug affecting both Win/Linux intermittently
You can try to reproduce while taking a profile using the Firefox profiler, then share it in the #perf:mozilla.org room on Mozilla's Matrix instance.

Why does Firefox run slow
Run a profiling session for ~30 sec when you notice something is running slower than you expect, see https://profiler.firefox.com/. Share results here if you want help interpreting them.

Problems with Firefox non snap versions on Ubuntu 22.04?
Next time, send a SIGABRT to the main process (kill -6 $(pidof firefox)) and use the resulting backtrace (you will find a link to the crash report in about:crashes) to file a bug. A performance profile could be useful, but you'll need to know first what to capture. This seems like a graphics issue, so try the Graphics preset. Share a link to your report.

Dear Firefox, why are you so terrible at rendering Flutter web apps? It's like potato quality.
https://profiler.firefox.com will be useful if you can capture and share it to developers.
-
Webpages not loading or taking forever to load
If you can reproduce it in safe mode and a clean profile, capture a performance profile using the clean profile while trying to load a problematic webpage, don't remove any information from it, and share it here (although it's typically not easy for users to analyse them), or file a bug with it attached.

Firefox hangs on Facebook page
Next time, capture a performance profile using the Graphics preset, and kill the browser by entering kill -6 $(pidof firefox) in a shell. This will create a bug report (unless debian disables the crash reporter) that would indicate where Firefox is stuck at. You might need to use an official build to get useful results.
