Safari 17: Gets stuck when trying to convert video to png sequence in Multi-thread mode #628

Describe the bug When using Safari 17, trying to convert a video to a png sequence in multi-threaded mode, it gets stuck before finishing

To Reproduce

  1. Open the browser 'Safari' version 17
  2. Open https://ffmpegwasm.netlify.app/playground/
  3. Click 'Use multi-threading'
  4. Click 'Load sample files'
  5. Enter the following arguments: 
    [
"-i",
"video.webm",
"frame%04d.png"
]
  6. Observe the log. It gets stuck at 'video:40913kB audio:0kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: unknown'

Expected behavior Should complete the transcoding and output the png sequence in the virtual file system.

Desktop (please complete the following information):

Additional context It works fine when converting to video. It works for converting to png sequence if not in multi-threaded mode. Multi-threaded mode seems to be causing issues everywhere as it doesn't work at all (not even video to video conversion) in Chromium-based browsers as noted in #597.
