I have at least two use cases for this:

  • Media classification as part of the user upload processing pipeline of a public file hoster (flagging potentially unwanted media to assist moderation)
  • Automatic description suggestions for alt-text in a social media server software (accessibility, moderation)

It’d be nice to have one of the DNN backends in libavfilter, but feel free to reject/disable by default if this dependency is hard to justify.

I’d be wary of it because OpenVINO is a bit heavy and fragile for something as critical as FFmpeg to depend on, and comes with the usual problems you might know from other packages under the science: prefix, including but not limited to:

  • CMake build system woes
  • API/ABI instability
  • Strictly requires specific and very old versions of some dependencies (which also have no API stability)
  • Might not build correctly with the default compiler (it currently builds explicitly with GCC 13 in openSUSE)

I reverted this. Factory would not take it: the build-time dependency chain has become too long, considering ffmpeg is a ring1 package (rather than "leaf").

The only way out I see here is if ffmpeg upstream were to develop a mechanism to (a) support building codecs a-posteriori, which implies (b) supporting dlopening such codecs.
