please allow me know if question doesnt belong stackoverflow can move accordingly.

objective: i) want convert mp4 mov , vice versa. ii) want create thumbnail video iii) rotate thumbnail if needed ( looking @ meta info information of image)

solution tried until now: i) (http://www.xuggle.com/xuggler/ - thumbnail ii) https://www.ffmpeg.org/ - convert video formats. iii) rotation : java code.

i able perform accomplish objectives using above solution in above solution reading stream 3 times , hence causing performance issues.

is there single library or solution of them doesn't slow downwards , cause performance issues?

the libav library satisfy requirements. library behind ffmpeg, building own tool on top of library can accomplish 3 steps in 1 read of source stream. wikipedia entry library has improve overview description project homepage.
