  configure : check SDL2 function with a header
  SDL2 uses SDLCALL to specify a calling convention. On OS/2, it's defined
  
  to `_System' which is similar to `_cdecl' but does not prepend '_'.
  After all, without a header, a function is used without `_System'. And
  
  linker will try to `_func' but fail because the function is `func' not
  
  `_func'.

• Async function doesn't pop off a second time

  9 août 2020, par Chris

  I'm creating a button to record a canvas using FFMPEG. Here's the code that finalizes the download process.

  


  const recordButton = document.querySelector("#record")
recordButton.addEventListener('click', function () {
function startRecording() {
const { createFFmpeg } = FFmpeg;
const ffmpeg = createFFmpeg({
  log: true
});

var transcode = async (webcamData) => {
  var name = `record${id}.webm`;
  await ffmpeg.load();
  await ffmpeg.write(name, webcamData);
  await ffmpeg.transcode(name, `output${id}.mp4`);
  var data = ffmpeg.read(`output${id}.mp4`);

  var video = document.getElementById('output-video');
  video.src = URL.createObjectURL(new Blob([data.buffer], { type: 'video/mp4' }));
  dl.href = video.src;
}

fn().then(async ({ url, blob }) => {
  transcode(new Uint8Array(await (blob).arrayBuffer()));
})

...

id += 1}


  


  The problem arises with the transcode variable. While the button works initially, every other attempt (on a single page load) fails just the async function. I'm not well versed enough in the function to know why it would only work once. That said, I do know it is the only bit of code that does not fire off upon second attempt.

  


  It could be a few things. This is borrowed code, and I've repurposed it for multiple uses. I may have messed up the declarations. It may be an async issue. I tried to use available values to rig up a secondary, similar function, but that would defeat the purpose of the first.

  


  I tried clearing and appending the DOM elements affected, but that doesn't do anything.

  ffserver_config : remove ffserver_apply_stream_config function
  This function became very short and can be logically merged with add_codec().
