About JPEG Decode in i.MX6Dual Lite with Linux BSP

Dear all,

 

We want to make application of JPEG Decode using VPU.

- OS is Yocto Linux BSP(fsl-yocto-3.14.28-1.0.0) of NXP.
- Board is MX6DL-SABRE-SDP.

 

We have the following questions.
May I have advice?

 

[1]
Files of different size and format cannot be decoded in succession.
When some JPEG files of the different size are decoded in succession,
Is there the method to decode in succession without performing Open/Close of VPU_Decoder?

If it is possible, may I have advice about a setting method?

 

[2]
A "JPEG decode result" changes by file format(before decoding).
(JPEG file => decode => YUV420 or YUV444 format)

Is there the method to fix the format of the decoded file?
(For example, formats are only YUV444.)

If it is possible, would you tell me the method with a format as RGB?

 

May I have advice?

 

Best Regards,
Yuuki
