Convert your WebM to ProRes

Like many of you lucky enough to purchase a PS5, I have been enjoying my time with the new console. One feature I started playing with is the video game capture feature via the "Create" button. I have been capturing my favorite clips here and there and selected the best ones to include a video I want to share. Unfortunately, I ran into trouble. None of my video editing applications (FCPX, DaVinci) support the WebM container. My favorite clips were all captured using WebM.

If you like me have all your favorite clips stuck in WebM then I have a solution for you. FFmpeg! This free software includes a ProRes encoder that simple enough to use works on Davinci Resolve (free version available) and Adobe Premiere! (FCPX of course supports ProRes.) See links below.

MacOS (and Linux)

On the MacOS, you can use the following command (Bash) to convert all WebM files in the current directory to ProRes.

Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:

class AsyncBlockOperation: NSOperation {
    typealias Block = (Void -> Void) -> Void

    private let block: Block
    private var _executing = false
    private var _finished = false
    
    init(block: Block) {

Open In... - Dateien senden in iOS-Apps

Eine iOS-Anwendung kann eine Datei an eine andere App übergeben, z.B. damit diese angezeigt oder anderweitig verarbeitet wird. Die Datei wird dabei allerdings kopiert, weil iOS es nicht erlaubt, dass sich Apps Ressourcen teilen.

Hier ist ein Beispiel, wie es geht:

@interface ViewController ()

@property (nonatomic, copy) NSURL *URL;

spinogrizz

- (UIImage *) imageByTrimmingTransparentPixels {
	int rows = self.size.height;
	int cols = self.size.width;
	int bytesPerRow = cols*sizeof(uint8_t);
	
	if ( rows < 2 || cols < 2 ) {
		return self;
	}
	
	//allocate array to hold alpha channel
