Can more threads access DSP server concurrently

Manjur49555

Hi,

We are using DM6446 board with h264 codec. We saw in the demo source code of DVSDK2.0 is that one thread is doing encode and decode both.

Is it possible to use one thread to encode h264 and another thread to decode h264? I found if two different processes access DSP codec server then they need to use LAD.

Is LAD needed for two separate threads to access DSP server?

Thank you

Manjur,

No, you don't need LAD for this. Each thread in a single process should call Engine_open() themselves (and not attempt to share an Engine_Handle from a single Engine_open()) and get a thread-specific Engine_Handle, and then they can each operate independently of each other.

Here's a link to a Wiki page that mentions pretty much the same thing that I said, you might feel more comfortable reading something "official"...
