How to apply effects to video stored in sdcard in android
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 ;-])
Ok thanks berak.. No I am looking for video not image..
o_O where the hell did @berak talked about audio signals? You lost me there -_-
@Namarata, look back a page or two, there was someone recommending a mp4 lib, that looked easy.
