Hi, experts

I'm doing the  speed test, and I'm using

[Setup]

Processor: DM6467T

Test software: dvsdk_3_10_00_19/dvtb_4_20_10

[Test steps]

1. delete all the code relate to file read and display and repeatly decode a same I frame

2. Use h264dec2 algrithm library

3. Use h2641080p60vdec algrithm library

[Result]

2. The decode speed is 27 fps.

3. The decode speed is only 27 fps.

 

[problem]

 How can I get the decode rate up to 60fps?

    Hello,

    Please use the decode, encode and encodedecode demos in the dvsdk for performance testing, and make sure your media clips are on the HDD as NFS will impact your performance.

    DVTB is mostly for codec accuracy and regression testing, as one can manipulate the codec parameters using scripting.

    Hi,Niclas

        Yes you are right, I do a simple test and can see the speed is accelerated trimendously.

    My project is almost done and left only the speed thing that almost make me crazy.

    Thank you very much.
