OpenVINO bloat

[tadejsv]

Comment:

Is it really necessary to bundle in OpenVINO? It significantly increases the size of this package, for a feature that 99.99% of the users will not need.

hmm, this is a fair question.

@ilya-lavrenov can you help us understand all the different intel solutions:

• OpenVINO
• VAAPI
• Intel Quick Sync

@ilya-lavrenov I know ffmpeg supports many "hot" plugins. Can we have openvino as a "soft" dependency similar to how the cuda dependency will "gracefully fail" if cuda isn't installed on the end user system?

Regarding:

for a feature that 99.99% of the users will not need.

Much of FFMPEG's strength comes from its great flexibility. Each users likely only uses 1-2 features, but FFMPEG makes them all interoperable.

It seems that compiling with openvino makes it a hard dependency:

conda uninstall --force libopenvino --offline --yes
ffmpeg -hide_banner -f lavfi -i nullsrc=s=256x256:d=8 -vcodec libopenh264 -f null -
ffmpeg: error while loading shared libraries: libopenvino_c.so.2440: cannot open shared object file: No such file or directory
