Question by Aresx · Jun 08, 2018 at 09:20 AM · slow threads picture jpg encode

EncodeToJPG is too slow. Blocking main thread.Is there new way alternative？

     private byte[] EncodingJPG(Texture2D texture2D)
     {
         byte[] bytes = texture2D.EncodeToJPG(20);
         return bytes;
     }

EncodeToJPG is too slow. Blocking main thread.I have already tried Coroutine,but still very slow.If I need to execute this method continuously,What should I do？

Coroutines run on the main thread as well, so that won't help. You would need to run it on a separate thread for it to not block, but I'm not sure Unity will allow to access the memory of a Texture2D on a separate thread.
It seems there is a newer API call ImageConversion.EncodeToJPG(). $$anonymous$$aybe that is faster?

From what I have seen, you can't put EncodeToJPG in another thread. $$anonymous$$aybe there is an other way to to do this, maybe it is faster. Try what @Harinezumi suggested, it might be faster.
