Doom in the iPhone photos app (barely)

I recall many years ago I was able to extend a video by multiple minutes of a black screen, by extracting the timestamps (PTS?) of frames to a text file, then increasing the timestamp of the final frame (or end of video?) by a very large number. Sadly I'm unable to find the files or program I used to do it.

They played fine on my laptop, but would not scan as gifs in iOS. It was a nightmare of a problem to debug - what are your search terms here? The GIF specification, GIFs that work and those that don't, and a hex editor. Given all the other impressive work in this article, I'm surprised that wasn't an easy problem for them to debug --- the latter seems almost trivial to me (find the differences) in contrast to the amount of creative thinking required to figure out how to run Doom in iPhone Photos.

  I guess this shows how different skillsets are. Debugging gifs also sounds a lot easier to me than setting up a remote controlled doom and screencapturing it, but I guess it all depends on your prior experience.

If I’m reading this right, this is yet another example of people claiming to run Doom somewhere, but is actually only displaying Doom, while Doom is running somewhere else, on another system.

  Essentially a "VNC client in iPhone Photos App"

  I must admit that I was excited about the idea of reading how to take C code and translate it to iOS shortcuts. Sure it's slow, but it's a wonder that the pig sings at all. How disappointed I was when I read more of TFA.

I thought that this was going to be another article talking about how apple really messed up the photos app this time around.

Now I am left wondering if you can do interesting things in the Files.app with the WebDAV support, and quick previews.

This is boarder line a 'choose your own adventure' style thing. It is so stupid it had to be done!

  "border", not "boarder" Also it's "borderline" one word, not "border line". It's a compound word. A boarder is someone who boards at a boarding school. A border is an edge, a boundary.

A bit off topic but is there any good resources to get started and learn about iOS shortcuts?

eieio.games uses an invalid security certificate. The certificate is not trusted because it was signed using a signature algorithm that was disabled because that algorithm is not secure. Error code: SEC_ERROR_CERT_SIGNATURE_ALGORITHM_DISABLED
