Elecard MPEG-2 Video Decoder with DXVA Support

Our engineers have tested the Elecard MPEG2 Video Decoder performance on different kinds of platforms using DXVA and Overlay. We took the measurements of the average CPU usage with the Graph’s Clock option enabled (i.e. when a clip is played back with a required frame rate) and frame rate values with the Graph’s Clock option disabled (i.e. when CPU and VGA are used at maximum).

Based on the test results, we came to the conclusion that the DXVA mode usage decreased the processor loading up to 50% as well as increased the frame rate up to 50%.

The few results of our measurements are listed in table below:
