Problem about LAD
I'm developing a video encode/decode system on evm6446. Encoder and decoder are different processes.
Both process call the same x64P loopbackCombo.x64P which is from DVSDK. The version Codec Engine is 2.10
I read the article about the LAD (http://wiki.davincidsp.com/index.php?title=Link_Arbiter_Daemon) and start lad.x470MV before any CE process.
If I run Encoder or decoder alonely, everything works OK. If I run Encoder/decode rat the same time, the later started process will fail
with calling of Engine_open with error code is 4. Could anyone help me?
I paste .cfg of my application and log.txt of lad.x470MV here.
