PROCESSOR-SDK-DRA8X-TDA4X: AR0233 in built ISP + TDA4X JPEG Capture Decode usecase issue

Prashant A

Part Number: PROCESSOR-SDK-DRA8X-TDA4X

Hi,

I am trying to develop an application with JPEG input to TDA4X from AR0233 in built ISP sensor and decode JPEG on TDA4X and dump YUV data.

I referred test_video_decoder.c testSingleStreamProcessing and created own application in vision_apps. I am able to decode H264 frame but Not able to decode JPEG frame.

I am getting below error for JPEG stream:

915408.791392 s: VX_ZONE_ERROR:[tivxAddKernelVideoDecoderValidate:166] Decoder param 'bitstream_format' should be: TIVX_BITSTREAM_FORMAT_H264

Note is there in j7_video_decoder.h file : \note Only \ref TIVX_BITSTREAM_FORMAT_H264 format supported in this release.

I am using psdk_rtos_auto_j7_07_00_00_11 version of SDK. Is there any release where I can get JPEG decoder support?

Prashant

Hi,

In TDA4X TRM, it is mentioned that JPEG decoder is supported.

Hi Prashant,

Yes, TDA4 Decoder HW supports JPEG Decoding, however RTOS SDK Video decoder driver doesn't support it.

Here is the Video decoder user guide from SDK that lists down all the supported features in driver and OpenVX:

https://software-dl.ti.com/jacinto7/esd/processor-sdk-rtos-jacinto7/latest/exports/docs/video_codec/docs_decoder/user_guide/rtos_docs/index.html

Please check if you can use ARM based MJPEG decoding for your use case.

Thanks & Regards,

Sunita.
