问题 I keep hoping some code will appear on the internet, but getting nowhere ;) WebRTC incoming I420Frame object seems to have 3 arrays of yuvPlanes A typical Android camera app gets PreviewCallback.onPreviewFrame byte[] as a single array of bytes. Can someone help me in how to convert I420Frames yuvPlanes to a single byte[] array like PreviewCallback.onPreviewFrame byte[] YCbCr_420_SP (NV21)? For reference, VideoStreamsView.java has this code to render to OpenGL - but I just want it like camera

问题 Ok guys, this may sound dumb, but I have been banging my head against the keyboard for some time now trying to figure out why this will not refresh. the basics: I have a little sample app that i am testing to see if i can rotate an image around a point a X amount of degrees, and show it one degree at a time to make a smooth animation. So I have a great sample i found that works great with a slider bar, basically setting the images rotation to a point on the slider bar, great! but.... when i

问题 I'm dealing with a random problem which related to camera usage. Before I call camera intent - I generate UUID to store file with this name. I store this UUID in private variable like so: private String requestedFileName; When camera done - I'm processing this file, looks something like this: public void onPictureTaken(int index) { //First of all - remember picture in database for reference.
