Import videos from Android internal/sd memory

[leonecaramanica]

Hi, sorry for the question but I can't figure it out what I'm doing wrong, It's 2 days that I'm looking for examples and trying to import a .mp4 video from sd card path but each time the file can't be found. The path is checked without errors, is it possible to import external videos or I made a big mistake?

Here's the code, but as I said, openVideo returns null, so I can't get the frame number

Hate to break the bad news but you're trying to use a method designed for Desktop only use on Android. I'll see if I can figure out some way to make it fail in such a way that you know what's going on! What i think is happening is that it can't find a codec to open the file so it returns null. It's been a few years since I've tried to process video on Android. There's a way you can do it with FFMPEG but there might be better ways to do it now.

So I was just looking at the FFMPEG used in BoofCV. There's actually a chance you could do a special build and get it to work. You can specify which native architectures you wish to support using a command line argument. native_arch what that will do is attempt to download precompiled libraries from bytedeco.javacpp-presets which has builds of the library for Android. I've never tested though...
