[SDL] "Xlib: unexpected async reply" with Mplayer embedded‏

[vijayendra.agrawal at wipro.com]

This happens because the Xlib seem to be not thread-safe.
 
You would need to only ensure that the display updates happens only from the main thread only, you would not face this issue. 
 
>From the thread receiving asynchronous message, you need to signal the thread waiting under the context of main thread as and when asych message arrives and the main thread should do the job of display updates.
 
Hope this helps.

Hi Everyone,

I have an SDL application which has a Mplayer embedded. I often get the error: "Xlib: unexpected async reply". I found in mail-list there are a lot of discussions about "Xlib: unexpected async reply" problem. Based on these discussions, I guess, this problem is because Xlib functions are called in two threads(one is my main thread, i think there is another one in Mplayer). For my case, I can't combine two threads into one, what should I do to avoid this problem? Any suggestion would be very appreciated.

Thanks
