I use example code as following to try open MP4 video file and put some text to video file but open result always return failed.

extern "C" { .... something code............

const char* arrURL = "mnt/sdcard/Download/VID_20140317_104750.mp4"; string source(arrURL);

VideoCapture inputVideo; // Open input //inputVideo.open(source);

if (!inputVideo.open(source)) -> alway return false here... { env->ReleaseStringUTFChars(URL, arrURL); env->ReleaseStringUTFChars(sInputText, arrInputText); return; } ....

i used eclipse CDT - juno, NDKr9, OpenCV 2.4.8 do everyone can help me answer some questions? - VideoCapture can not be supported on android? - Do you know any other solution on android? (not FFMPEG lib)

Thanks
