  libavcodec/x86/vvc: Add AVX2 DMVR SAD functions for VVC - Stone Chen git.videolan.org Git - ffmpeg.git/rss log
  libavcodec/x86/vvc: Add AVX2 DMVR SAD functions for VVC Implements AVX2 DMVR (decoder-side motion vector refinement) SAD functions. DMVR SAD is only calculated if w >= 8, h >= 8, and w * h > 128. To reduce complexity, SAD is only calculated on even rows. This is calculated for all video bitdepths, but the values passed to the function are always 16bit (even if the original video bitdepth is 8). The AVX2 implementation uses min/max/sub. Additionally this changes parameters dx and dy from int to intptr_t. This allows dx & dy to be used as pointer offsets without needing to use (...)

  How to stream lossy audio in chunks? [closed] - Adam Newest 'ffmpeg' Questions - Stack Overflow
  On the client side, I'm collecting periodically received audio slices into a circular buffer during the playback to avoid having to receive the entire file at once, only a small portion of its size. On server side I tried splitting MP3/M4A/OGG into frames, but even with ffmpeg, a gap is created in the chunk (usually at the beginning/end), which prevents me from validly concatenating them on the client side. Not even when I encoded the MP3 to PCM beforehand and then split the WAV file into MP3 chunks. Of course, split to WAV chunks there is no gap, but one slice is larger than (...) --

  Generating timestamps in webm transport stream with ffmpeg - Vlad Feinstein Newest 'ffmpeg' Questions - Stack Overflow
  I am recording screen capture of my Electron app to a file, as suggested here: Save captured video to file in Electron It works great, but the file is a “transport stream”. I can play it in Chrome browser, but can’t adjust the time slider. The suggestion was to use ffmpeg to post-process the file. The simplest, straight-forward command I found is: ffmpeg -fflags +genpts -i in.webm out.webm I thought that this simply generates timestamps. However, the out.webm file is 15 times smaller than in.webm! I don’t see any change in the quality. The downside is - the (...)

  PHP/ffmpeg (Windows 7): - Permission Denied. Tried everything, but still doesn't work - user365465 Newest 'ffmpeg' Questions - Stack Overflow
  I have a command-line PHP script that, when given the folder name as an argument when executing the script, will find all images in said folder and resize them using FFmpeg.

The q is however shown in the terminal (...)
