java - Efficient Webcam Library -

-

i need extremely efficient webcam library (i'll explain later) works on platforms.

basically there 2 webcams , need alternate between them @ fast rate (a least 50fps, has fluid video still)

anybody have experience in field , have suggestions?

while developing webcam capture project i've tested several frameworks , decided use part of openimaj framework. had extract part of core-video-capture subproject , refince code remove necessary dependencies has. when included refine code in project able stream 250 fps (edit: due bug in windows impl) 50 fps bufferedimage objects (on windows xp, without painting, fetch image webcam). can recommend since compatible operating systems - windows (x86 , x64), linux (x86, x64 , arm), mac os. if interested, can find refined code here.

jmf fast, pretty outdated , not maintained more. it's not portable - when want use it, have install jmf.

i don't recommend javacv, require huge opencv installation package (~100mb), have no java documentation , it's not portable.

lti-civil / fmj outdated, not being maintained more.

vlcj work correctly on linux (since using v4l4j) , have have vlc installed on pc (not portable).
