Recording video on Android using JavaCV (Updated 2014 02 17)
25 septembre 2014, par Fabio BergmannI’m trying to record a video in Android using the JavaCV lib.
I need to record the video in 640x360.I have installed everything as described in README.txt file and I followed the example as below :
https://code.google.com/p/javacv/source/browse/samples/RecordActivity.java
In this example, the video size is this :
private int imageWidth = 320 ;
private int imageHeight = 240 ;In my case, I need to record a video in 640x360 H.264.
(UPDATE) I have reverted my code and kept exactly like in the example, just changing imageWidth and imageHeight to 640x360.
Now I’m getting the video like this image :
