I have also facing the problem. ndk-build successfully build cvCreateFileCapture(filename). But unfortunately it returns the NULL value for a valid video filename staying in sdcard. Now my question is, is it possible to use cvCreateFileCapture() for capturing video or not or there are any other alternative.

Hi, I have a question about the openCV4Android:
I have a openCV program build on windows PC which uses the cvCreateFileCapture(filename) to open a video, and I wan't to port that program on android. Now I have successfully build with ndk-build and openCV4Android-2.4.2-native-sdk downloaded from , when I try to run on Android, the cvCreateFileCapture just return NULL while it's working on PC. I checked the video path is right, and tested cvLoadImage, that's working too.
I want to know whether the method is supported on Android? If not, Is there any way to create a VideoCapture from a Video not the Camera?
