xav

Xav Elixir wrapper over FFmpeg for reading audio and video files. See an interview with FFmpeg enthusiast: https://youtu.be/9kaIXkImCAM Installation Make sure you have installed FFMpeg (ver. 4.x - 7.x) development packages on your system (see here for installation one-liners) and add Xav to the list of your dependencies: Controlling FFmpeg log output FFmpeg's underlying libraries (libavcodec, libswscale, ...) print to stderr at the AVLOGINFO level by default. This is usually fine but can produce informational noise such as when libswscale falls back to a generic colorspace conversion path. These are not errors — decoded frames are bit-exact — but they can clutter test output and logs. You can raise the threshold from Elixir: Or set it once at application start by configuring your application env: Xav.Application reads this on boot and applies it before your supervision tree starts. Valid atoms are :quiet, :panic, :fatal, :error, :warning, :info, :verbose, :debug, and :trace. An integer FFmpeg level is also accepted.
