• FFMPEG + HW Acceleration + Kepler GPU Lossless encoding not supported ?

  11 juillet 2022, par user2522885

  I'm curious about FFMPEG and GPU hardware acceleration. My Windows 10 system uses the Asus / nVidia GTX 760 graphics card and Intel i5-2500K CPU. My graphics card claims to be of the Kepler architecture with CUDA 3.0 as shown here.

  


  Instead of going through the hassles of compiling FFMPEG with hw acceleration support i downloaded a pre-compiled binary from here and here.

  


  Next, i tried running a test with hw acceleration options as recommended here :

  


  ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -i "input.mkv" -c:a copy -c:v h264_nvenc "output.mp4"


  


  I then received the error message :

  


  [h264_nvenc @ 000001c34eeda8c0] Lossless encoding not supported
[h264_nvenc @ 000001c34eeda8c0] Provided device doesn't support required NVENC features
Error initializing output stream 0:0 — Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

  


  What am i doing wrong ? For the record i install the CUDA setup file but it made no difference. I am using the latest nVidia drivers.

  


  UPDATE

  


  ffmpeg -h encoder=h264_nvenc

• Matomo Celebrates 15 Years of Building an Open-Source & Transparent Web Analytics Solution

  30 juin 2022, par Matthieu Aubry — About, Community

  Fifteen years ago, I realised that people (myself included) were increasingly integrating the internet into their everyday lives, and it was clear that it would only expand in the future. It was an exciting new world, but the amount of personal data shared online, level of tracking and lack of security was a growing concern. Google Analytics was just launched then and was already gaining huge traction – so data from millions of websites started flowing into Google’s database, creating what was then the biggest centralised database about people worldwide and their actions online.

  So as a young engineering student, I decided we needed to build an open source and transparent solution that could help make the internet more secure and private while still providing organisations with powerful insights. I aimed to create a win-win solution for businesses and their digital consumers.

  And in 2007, I started developing Matomo with the help from Scott Switzer and Jennifer Langdon (who offered me an internship and support).   

  All thanks to the Matomo Community

  We have reached significant milestones and made major changes over the last 15 years, but we wouldn’t be where we are today without the Matomo Community.

  So I would like to celebrate and thank the hundreds of volunteer developers who have donated their time to develop Matomo, the thousands of contributors who provided feedback to improve Matomo, the countless supportive forum members, our passionate team of 40 at Matomo, the numerous translators who have translated Matomo and the 1.5 million websites that choose Matomo as their analytics platform.

  

  Matomo has been a community effort built on the shoulders of many, and we will continue to work for you. 

  So let’s look at some milestones we have achieved over the last 15 years.

  Looking back on milestones in our timeline

  2007

  Our efforts continue

  While we’ve seen incredible growth over the years, our work doesn’t stop there. In fact, we’re only just getting started.

  Today over 55% of the internet continues to use privacy-threatening web analytics solutions, while 1.5% uses Matomo. So there are still great strides to be made to create a more private internet, and joining the Matomo Community is one way to support this movement.

  There are many ways to get involved too, such as :

  • Submitting feature requests
  • Developing for Matomo 
  • Leaving Matomo a review on sites like Capterra, TrustRadius, G2 Crowd, alternativeTo, SaaSworthy, Siftery, Open Hub
  • Translating Matomo
  • Joining our Security Bug Bounty Programme
  • Sharing Matomo with your peers
  • Talking about Matomo on social platforms

  So what comes next for Matomo ?

  The future of Matomo is approachable, powerful and flexible. We’re strengthening the customers’ voice, expanding our resources internally (we’re continuously hiring !) and conducting rigorous customer research to craft a tool that balances usability and functionality.

  I look forward to the next 15 years and seeing what the future holds for Matomo and our community.
