Can somebody please let me know whether OpenCv can be used for applying effects like greyscale, sepia, emboss, sharpness, increase or decrease brightness etc to a video retrieved from sdcard in android. It would be a great help if somebody could help me out with some sample code if it's possible as I am new to OpenCV. Thanks in advance.

first: no, you can neither read nor write video files with opencv (on android / java. camera or single images - no problem). you will have to come up with your own solution for that.

then, if you're searching for some image effect processing samples, - look around on this page,try the search-box above, you will find plenty. (almost anyone on android seems to start like that ;-])

@Namarata, look back a page or two, there was someone recommending a mp4 lib, that looked easy.
