I am quite new in OpenCV. I am working on a project to open/play a stored mp4/avi from the raw folder in android and detect faces in the video. For last many days i am touching many tutorial but unfortunately i am not able to get the same. Any suggestion, tutorial link etc will be appreciated. Thanks in advance. I am using OpenCV-3.4.0.

you're a bit out of luck with this idea.

on android (lacking a backend like ffmpeg or gstreamer) only mjpg encoded avi files are supported, so you cannot read arbitrary video files.

then you cannot read from the raw folder directly (because it is zipped within your apk), but you would have to copy your video to sdcard manually first.

Yeah, I was wrong, I am getting the video from gallery obviously that are stored in SD-Card. So, with out FFmpeg, we can't accomplish the task using openCv(cv::VideoCapture etc). Am I right?

yes, exactly. you're limited to mjpg/avi.
