  • NAB 2019: Haivision Announces Peer-to-Peer Low-Latency Streaming for Its SRT Framework

    Prior to releasing SRT P2P to the open-source community, Haivision is seeking partners to collaborate and stress-test the technology at scale.

    [...]

    SRT P2P is the latest development for the SRT (Secure Reliable Transport) initiative that Haivision started in 2017 when the company open-sourced the SRT protocol and technology stack. SRT has been endorsed as a low-latency contribution and distribution streaming protocol by more than 200 companies across the broadcast and streaming industries. With a focus on video delivery, SRT P2P extends the SRT initiative to create a comprehensive framework for high-performance streaming from contribution through distribution and into delivery.

  • Netflix and Intel to Deploy AV1 CODEC For Content Streaming

    At The National Association of Broadcasters Show today, Intel and Netflix announced a new high-performance video codec that is available as open source and royalty-free to content creators, developers and service providers. Scalable Video Technology for AV1 (SVT-AV1) offers performance and scalability in video processing.

    AV1 is a royalty-free codec and offers improved compression compared to vp9 or hevc, the video bandwidth reduction can run upwards to 30 to 40 percent, without you seeing a difference. The best thing yet, this is a royalty-free model. 

  • NAB '19: Netflix and Intel Release SVT-AV1 Codec as Open Source

    This morning at NAB, Intel and Netflix together announced the SVT-AV1 codec which is capable of real-time 4K/60p 10-bit encoding when running on Intel Xeon Scalable processors and Intel Xeon D processors. To our knowledge, this is the first software-only AV1 implementation capable of real-time encoding and it represents an order of magnitude acceleration of AV1 encoding. The companies released SVT-AV1, or Scalable Video Technology for AV1, into the open source community for immediate availability.

Programming: Thread Synchronization, Python, C++

  • Thread Synchronization in Linux and Windows Systems, Part 1

    In modern operating systems, each process has its own address space and one thread of control. However, in practice we often face situations requiring several concurrent tasks within a single process and with access to the same process components: structures, open file descriptors, etc.

  • Intro to Black – The Uncompromising Python Code Formatter

    There are several Python code checkers available. For example, a lot of developers enjoy using Pylint or Flake8 to check their code for errors. These tools use static code analysis to check your code for bugs or naming issues. Flake8 will also check your code to see if you are adhering to PEP8, Python’s style guide.

  • Report from the February 2019 ISO C++ meeting (Library)

    Back in February, I attended the WG21 C++ standards committee meeting in rainy Kona, Hawaii (yes, it rained most of the week). This report is so late that we’re now preparing for the next meeting, which will take place mid-July in Cologne. As usual, I spent the majority of my time in the Library Working Group (for LWG; for details on the various Working Groups and Study Groups see Standard C++: The Committee). The purpose of the LWG is to formalize the specification of the C++ Standard Library, i.e. the second “half” of the C++ standard (although in terms of page count it’s closer to three quarters than half). With a new C++20 standard on the horizon, and lots of new features that people want added to the standard library, the LWG has been very busy trying to process the backlog of new proposals forwarded by the Library Evolution Working Group (LEWG). One of the main tasks at the Kona meeting was to review the “Ranges Design Cleanup” proposal. The cleanup involves a number of fixes and improvements to the new Ranges library, addressing issues that came up during the review of the previous (much larger) proposal to add the Ranges library, which is one of the biggest additions to the C++20 library (most of the other significant additions to C++20 affect the core language, without much library impact). In fact, I’d say it’s one of the biggest additions to the C++ standard library since the first standard in 1998. The Ranges library work overhauls the parts of the standard that originated in the Standard Template Library (STL), i.e. iterators, algorithms, and containers, to re-specify them in terms of C++ Concepts. This has been a multi-year effort that has now landed in the C++20 working draft, following multiple proposals and several meetings of wording review by LWG.

  • Save and load Python data with JSON

    JSON stands for JavaScript Object Notation. This format is a popular method of storing data in key-value arrangements so it can be parsed easily later. Don’t let the name fool you, though: You can use JSON in Python—not just JavaScript—as an easy way to store data, and this article demonstrates how to get started.

Raspberry Pi 4 and Raspbian Buster: Hands-On

In my previous two posts I looked at the Raspberry Pi 4 hardware and at the procedure for installing and booting the new Raspbian Buster Operating System on the Pi 4. With those basic steps out of the way, now it's time to look at both the hardware and software in more detail. The first thing I want to mention is that when I wrote the previous post about Raspbian, I had not noticed that there is an updated version of Raspbian Buster (2019-07-10) available. This version was released sort of quietly (without the usual blog post announcing and explaining it), although there are release notes for it if you are interested. This release is extremely good news, because it fixes some of the biggest problems that I mentioned in my previous post... Read more
