TDA2PXEVM: Compression Decompression Feature in Vision SDK

NEPHIL SEBASTIAN P J

Part Number: TDA2PXEVM

Hi All,

We are using vision SDK v3.07

I would like to use Compression and Decompression to store/retrieve LUT's.

Is there any Compression Decompression feature available in Vision SDK

Regards,

Nephil

Use Encode & decode link

Can we compress data using Encode link?? if yes,Is there any sample usecase using Encode link to compress data available?

Refer the below use-case:

C:\PROCESSOR_SDK_VISION_03_02_00_00\vision_sdk\apps\src\hlos\adas\src\usecases\lvds_vip_multi_cam_vpe_enc_null\

Hi,

I have created a use case as below.

NullSource (A15) -> Decode -> VPE -> Encode -> Null (A15)

How to verify that Decode and Encode is working Properly and data is compressed/Decompressed??

How to calculate the compression ratio achieved by encode link??

Hi Nephil,

compression ratio depends on encoder settings like encoding bitrate, quality factor setting etc.

are you able to get the bitstream output from NULLsink? You can compare the frame size with the original size used in NullSrc.

Thanks

Hi Ramprasad,

encoder settings like encoding bitrate, quality factor setting etc i have given the values in

C:\PROCESSOR_SDK_VISION_03_02_00_00\vision_sdk\apps\src\hlos\adas\src\usecases\lvds_vip_multi_cam_vpe_enc_null\

What possible values can be given to achieve Good compression ration.

are you able to get the bitstream output from NULLsink?

i was not able to run the apps.out since i am getting error Attaching to [IPU2} while running apps.out

I will update once i am able to run and check the output

Thanks,

Nephil
