H.264 Decoder hangs on close

Hello,

I currently have a problem after upgrading from IPP 7.0.4 to 7.0.7 and the related UMC samples. Now, the H.264 decoder hangs within the close routine. I know, that this should be fixed since 7.0.6 and therefor I'm a little bit confused.

I have tracked it down to vm_mutex_lock function in which the deadlock seems to be.

Do I have to take anything else int account? Any help would be appreciated.

Thanks in advance and regards,
Christoph

Hello,

some additional information:

I could get around these problems by setting the thread numbers explicitly to 1 or 2 befor initiating the decoder. After this, close finished properly. The former initiation used 0 (as this is the default value) as threadNum value.

After all, is this a known issue or do I have to do anything different?

Regards,
Christoph
