Re: [Opalvoip-user] Application recording use 100% cpu when receiving call

[VEYSSIERE N. <nic...@th...>]

Update : because I was able to update to v3.14.1 (static link, see my other post), I can confirm that even the latest stable use 100% on somes call, and the generated wave file is empty (not really, it contains the wave riff header).

What can cause this ?

Objet : [Opalvoip-user] Application recording use 100% cpu when receiving call

Hello, I try to develop an application recording calls, I used the record sample application as example.

Because sometimes my soft is using 100% cpu power when a call is received (sip or h323). When this happens, the file is created but no data is written to it.

Because I tried to find if it is a problem in my code, I tried to use the opal record sample application to find if it happens also.


And because the sample application is doing the same thing, I would like to know if it is normal and have been corrected.


Here is the stack of the thread using 100% cpu :

Any help appreciated.
