Crazy regex for matching acceptable video inputs for AWS Elemental MediaConvert:

I got the error trying to convert a gif image.

BadRequestException: /inputs/0/fileInput: Should match the pattern:

This js code should expand the player to the width/height of the browser window.
window._fs__hbo_timeout;
window._fs__hbo = function(){
document.querySelector("#ifp").parentNode.setAttribute("style", "position:fixed;top:0px;left:0px;width:100vw;height:100vh;background-color:#000;z-index:2147483648;");
document.querySelector("#ifp").parentNode.setAttribute("id", "flvideo");
document.querySelector("#ifp").parentNode.parentNode.parentNode.parentNode.parentNode.parentNode.style.top = "0px";
document.querySelectorAll(".default").forEach(function(e){
var style = window.getComputedStyle(e);
if(e.getAttribute("id") != "flvideo" && style.position == "fixed"){ e.style.opacity = 0; e.style.zIndex = 1; }

dudewheresmycode / FFMPEG Scene Detection.md
Last active March 4, 2024 10:06
Notes on scene detection with FFMPEG

Basic ffmpeg scene detection:

ffmpeg -i input.flv -filter:v "select='gt(scene,0.4)',showinfo" -f null -

scene (video only) value between 0 and 1 to indicate a new scene; a low value reflects a low probability for the current frame to introduce a new scene, while a higher value means the current frame is more likely to be one (see the example below) https://ffmpeg.org/ffmpeg-filters.html#select_002c-aselect

Set the scene change detection threshold as a percentage of maximum change on the luma plane. Good values are in the [8.0, 14.0] range. Scene change detection is only relevant in case combmatch=sc. The range for scthresh is [0.0, 100.0].
