  • The Pros and Cons of Software Decoding for Publishers and Viewers

    3 weeks ago | streamingmediaglobal.com | Jan Ozer

    A recent paper from Friedrich-Alexander University benchmarks energy consumption and compression efficiency for six video codecs across software and hardware decoders. While the study uses VP9 as a reference, the more relevant comparisons for today’s streaming environment are between H.264 and HEVC in hardware, and AV1 and VVC in software, reflecting real-world deployments.

  • Software Decoding and the Future of Mobile Video

    1 month ago | streamingmedia.com | Jan Ozer

    With AV1 hardware decode on mobile devices stuck in the mid-to-low teens as of 2025, and with VVC at zero, it’s clear that the race to supplant H.264 and HEVC will be contested with software-only decoding. As we sit here in 2025, we know that Meta has aggressively started distributing AV1 streams for software-only playback and has even co-created an open source project called VCAT (Video Codec Acid Test) to help benchmark mobile devices.

  • x265 and WPP: What’s Fast Isn’t Always Efficient

    1 month ago | streaminglearningcenter.com | Jan Ozer

    If you’re optimizing x265 for speed, enabling Wavefront Parallel Processing (WPP) looks like a no-brainer. Table 1 shows a staggering 7.3x improvement in encoding time. A 3:15 encode with WPP turns into a painful 23:51 without it. The quality penalty? Negligible. VMAF drops just 0.19, with the low-frame VMAF off by only 0.77  (low-frame is the lowest VMAF score of any frame in the video, a predictor of transient quality issues).
