H.264 decoder fails to run with HEVC encoder

Hi,

In my transcoder I can't run multicore H.264 decoder (2 or 4 cores mode) with HEVC encoder simultaneously.

All works good when:

1) H.264 decoder runs in single-core mode with HEVC

or

2) H.264 decoder's process calls are not executed simultaneously with HEVC process calls.

or

3) When I use H.264 decoder with other than HEVC encoders (i.e. multicore or singlecore H.264 encoder).

But when I run H.264 multicore decoder simultaneously with singlecore or multicore HEVC encoder it hangs.
 HEVC encoder runs on core 4, H.264 decoder runs on cores 0-3.

Have you ever run transcoding: H.264 decoder with HEVC encoder?

I use H.264 decoder 01.01.04.00 and 01.01.04.02.

I use HEVC encoder from MCSDK Video 02.02.00.42 and 02.02.00.41
