tidus2020 commented 3 years ago

I want to play a swf ,10mb, it need 10sec to start. on some old android device even more than 30sec !

can this be optimized?

@tidus2020, many thanks for your issue report.

Unless you provide the Flash animation you have in mind, the rest of us doesn’t imagine which file you speak about 😅.

Testing may begin once you provided the file (or at least its address).

Many thanks for your help.

Many thanks for the address, @tidus2020.

Not sure what might be causing it, but could you check it with latest version (I wonder whether your version included 484bd2c11a628f17c9d0b52bb44a891da32b9f46 [and this might improve things a bit]).

@tidus2020,

I agree that http://main.miracle-cn.com/ruffle/lesson4.swf needs longer to be loaded with Ruffle that with Flash.

I don’t know whether this can be improved. But could you provide more information on how you use Ruffle?

  1. OS and version number.
  2. Processor architecture (32bit or 64bit).
  3. Browser and version number.
  4. How long does it take to open the same animation using the same browser with the Flash plugin?

I’m assuming that you are using a computer (desktop or laptop). Please, feel free to correct me, if I’m wrong.

Many thanks for your help.

On 20-12-2020, desktop, it was loading for like 7 sec first time, 4-5 seconds second time, on my computer, when Flash loads it immediatly indeed.

Windows 10 64bit

I'll put here links to flashes on z0r.de which are loading with delay on Ruffle.

https://z0r.de/6728 https://z0r.de/3987 https://z0r.de/2015

I left the info on them in the "z0r.de issues" issue I created: https://github.com/ruffle-rs/ruffle/issues/1766#issuecomment-744024317 https://github.com/ruffle-rs/ruffle/issues/1766#issuecomment-745517872

What they have in common is that they has "Unknown tag" errors littered in F12 console (Chrome). From what I've read here, it could be an obfuscation processing issues? Or those flashes do really have said unknown errorneous tags and Ruffle stutters a bit on them?

tidus2020 commented 3 years ago

I mainly in the mobile phone platform for the animation，and i do not need any as code.

This loads much faster now

ousia commented 3 months ago

@Lord-McSweeney, many thanks for all the optimizations.

As for me, http://main.miracle-cn.com/ruffle/lesson4.swf is loaded by Ruffle or by Flash equally fast.

@Diatonator and @tidus2020, could you confirm the improvements?
