A journey to First Frame with Vulkan Video - I wrote up the first part of my recent foray into bringing hardware accelerated video decoding to my R&D engine, Island:

Just released the latest version of Island - with this, Island becomes one of the very few open source graphics engines supporting Vulkan Video Decode - and possibly the first hot-reloading framework doing so 😜

Looks like all the tail chasing was good for something in the end:

Seems that I can't bank on the timestamps calculated by minimp4, but need to factor in out-of-order frames using the pictures' PictureOrderCount. I'm re-calculating the timestamp once i've re-ordered pictures from the stream - this won't fly in a streaming scenario, but it works for now...

I'm ending the week quite pleased, with a smoothly playing video. I shall happily go home & feed the protagonist. \o/

Progress, and lesson learned: if a picture says it isn't a reference picture, this needs to be respected. Now I need to figure out how to correctly calculate PTS (presentation time stamps) for frames which are encoded out-of-order...

On to the next challenge: decode a slightly more complex mp4. here is Milo chasing his tail ... looks like video decoding is rather elusive ... as are tails 🙈

We have a foreman who's pausing and playing, and animating at the correct framerate whilst looping seamlessly \o/
