This article details practical issues encountered when using Intel QSV hardware encoding with FFmpeg: H.264/H.265 video streams encoded with QSV only display keyframes on Hikvision DVRs, while P-frames fail to render properly. Through comparative testing, the author discovered that Nvidia NVENC hardware encoding doesn't experience this problem. The article provides an in-depth analysis of the root cause, along with complete code examples and solutions, including special parameter configurations for Intel QSV encoders such as forcing baseline profile usage, enabling CAVLC entropy encoding, and setting appropriate levels. These optimization measures effectively improve the compatibility of QSV-encoded video streams with Hikvision devices, addressing pain points encountered in actual development. For developers who need to use Intel integrated graphics for video encoding and stream to Hikvision devices, this article offers valuable reference material and practical solutions.

This article presents a disruptive perspective: AI's true power doesn't lie in creating content, but in consuming and understanding existing information. By connecting personal knowledge bases (like Obsidian) with AI, the author achieves deep analysis of years of accumulated notes, meeting records, and thoughts. AI can discover patterns difficult for humans to detect, connect seemingly unrelated ideas, and retrieve forgotten insights. This approach not only improves problem-solving efficiency but also helps make better decisions. The article emphasizes that the real transformation isn't viewing AI as a content generation tool, but as the ultimate reader of personal experience. Through continuous recording and AI analysis, everyone's knowledge can achieve compound growth, becoming a unique competitive advantage. This AI application model represents a shift from creation tool thinking to knowledge consumption thinking, providing new directions for personal knowledge management and AI application.

Mozilla's new CEO hinted in an interview that the company might block ad blockers in the Firefox browser, a move expected to generate an additional $150 million in revenue. The article's author expresses concern that this would undermine Firefox's core competitive advantage. As a long-time Firefox user, the author emphasizes that Mozilla's appeal lies in its commitment to open standards and the open web, as well as its powerful extension system. Ad blockers are not just user experience enhancements but crucial security features that prevent malicious ads. The article points out that removing this advantage would further alienate the core user base, who are often the source of technical advice for general users. The author calls on Mozilla not to forget its open-source mission and core values while pursuing commercial interests.
