Description

We noticed that javacv's grab (method of ffmegframegrabberr) base on ffmpeg and running on x86 . But our hardware is runnig on ARM, when we try to use grab to decode image ,it'll spend about 30s，which is too slow. The Hardware manufacturer has their own packaged ffmpeg (support c/python)，which only cost 1s to docode per image. So,is there the way that we can use manufacturer's packaged ffmpeg by java,to improve the decode efficiency。

Contributor guide

Research direction
Look into loading custom native libraries in JavaCV, specifically replacing the bundled FFmpeg with a vendor provided ARM build. Check JavaCV's documentation on native library loading and consider using system property 'org.bytedeco.javacpp.platform' or custom classpath. Also, explore using JNI directly.
