  Bootstrapping an AI UGC system — video generation is expensive, APIs are limiting, and I need help navigating it all [closed] - Barack _ Ouma Newest 'ffmpeg' Questions - Stack Overflow
  I’m building a solo AI-powered UGC (User-Generated Content) platform — something that automates the creation of short-form content using AI avatars, voices, visuals, and scripts. But I’ve hit a wall with video generation and API limitations. So far, I’ve integrated TTS and voice cloning (using ElevenLabs), and I’ve gotten image generation working.

  swresample/rematrix: Use correct function pointer types for calls - Andreas Rheinhardt git.videolan.org Git - ffmpeg.git/rss log
  swresample/rematrix: Use correct function pointer types for calls Calling a function via a different function pointer type is undefined behavior (C11, 6.3.2.3 8); two pointer parameters of different type are not equivalent in this regard, although it happens to work in practice; the current code relies on this.

Up to that point, UA had long been the default analytics platform, despite its many limitations. This was mostly because everyone loved its free nature and simple setup. A Google account was all you needed — even a free legacy G-Suite account worked perfectly. Looking at the analytics for just about any website was easy. That all changed with GA4, which addressed many of UA’s shortcomings by introducing a completely new way to model website data. (...) -- collection limits in GA4, configuration limits, GA4 supports only two

  avcodec/mpeg4videoenc: Fix data race when using AC prediction The check for whether we can use the fast path to process AC coefficients used the qscale value belonging to a different slice; this worked in practice, because the predicted AC values are zero in this case, so it does not matter whether we use the fast or the slow path.

  Consent management platforms: Keys to compliance and user trust - Joe Piwik
  Today’s marketing managers and data analysts face a tricky balancing act: gaining meaningful customer insights while respecting user privacy. Finding ways to navigate the maze of complex privacy regulations while managing consent at scale can be daunting. Consent management platforms (CMPs) offer a solution.

  libavformat/rtpdec: Fix RTP timestamp wraparound in Producer Reference Time - Clément Péron git.videolan.org Git - ffmpeg.git/rss log
  libavformat/rtpdec: Fix RTP timestamp wraparound in Producer Reference Time The rtp_set_prft() function incorrectly calculates the timestamp delta when RTP timestamps wrap around the 32-bit boundary. The current code: delta_timestamp = (int64_t)timestamp - (int64_t)s->last_rtcp_timestamp; treats both timestamps as large positive values, causing wraparound to produce a large negative delta instead of the correct small positive delta. For example, with a 90kHz video clock: - last_rtcp_timestamp = 0xFFFFFF00 (near wraparound) - timestamp = 0x00000100 (after wraparound) - Current result: (...)

  ffmpeg failed - 455 Method Not Valid in This State - paty.r15 Newest 'ffmpeg' Questions - Stack Overflow
