My work just published a slide to our social media profiles on all the work I've done on the new video player and other upgrades I made that we offer. It mentioned all of the cool stuff, except for the a11y stuff like captions, descriptions, and keyboard controls. That made me sad, and then I realized that whatever we were using likely didn't convert any of the text in that image to alt text and so far I've been right (which surprised me about FB since I thought they had OCR for mostly-text images)
