Trying to use FFMPEG for android. Compiling but still not working
15 avril 2014, par Austin MuellerSo to start off... Im trying to use ffmpeg to compile an array of images into a video on Android.
I have followed a variety of tutorials online and have gotten as far as being able to compile the lib for Android and still have to project run.
The repo im now using can be found here : https://github.com/Batterii/android-ffmpeg-x264I made a couple tweaks to the setttings.sh just to correct ndk location. Besides that, I followed the instructions and it seemed to work flawlessly.
After that, I converted the "Project" project into an Android stdio library module.
I am not getting any compile errors, nor am I getting any runtime errors, or any other errors that I can detect... Nothing on logcat... But I am definitely not getting any video called out.mp4.
In an onCreate of a particular activity, I am running this code :Videokit vk = new Videokit();
vk.run(new String[]{"ffmpeg", "-r", "1/5", "-i", "%d.jpg", "-c:v", "libx264", "-r", "30", "-pix_fmt", "yuv420p", project.getProjectDirectory() + "/out.mp4"});This command is taken from the command line example found here :
https://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20imagesThank you in advance for anyone taking the time to look through this post... I am pretty baffled at this point, as there are no errors I can find and no video...
Thanks======================================================================
Update
Turns out it is not actually compiling correctly... but i have found a few things.
here is the make file from the Eclipse version of the projectLOCAL_PATH := $(call my-dir)

Total time: 8.184 secsI've been messing around with it for a couple hours now and pretty much every time, i get gradle yelling at me about the fact that it can't find some file. I'm beginning to think that maybe it is because my LOCAL_LDLIBS aren't in the same order as the original...? Im not entirely sure... Does anyone else have any ideas...?

Android simple video editor app [on hold]
30 mars 2014, par gopgopI am working on a small android project..
The goal of the app is to pull video files from the library or images and combine those into a video and save it into the library.
I already have made the part where it pulls the images and videos, now I am stuck..
How would you go about combining the images and videos to make one video file using java and android ?
Can someone please guide me ?
I have looked around and did not find any clear winner,
I'd prefer not to use FFmpeg as its not pure java..Thanks.
