Dear nxp,

I have board IMX8MP processor and I found the problem like this thread

Re: IMX8MP and accellerated jpeg decoder - NXP Community

After I compiled and use linux-imx 5.15 and try to use gstreamer with packge gstreamer1.0-plugins-imx, libimxvpuapi2

It found error after test

gst-launch-1.0 -e -v multifilesrc location=/root/temp/image%04d.jpg start-index=0 stop-index=100 loop=true \ caps="image/jpeg,framerate=\(fraction\)1/1" \ ! jpegparse \ ! imxvpudec_jpeg \ ! fakesink OMX JPEG ! HantroHwDecOmx_decoder_create_jpeg JpegDecInit error openmax_il/source/decoder/codec_jpeg.c:1045

In that thread NXP TechSupport replied this

I would like to know how to modify package gstreamer to support jpeg decoder and encoder using VPU

Regards

Hello,

You can modify:

https://github.com/Freescale/gstreamer-imx

but the VPU comes in binary form.

Thanks for your reply,

Do you have suggestion or example code for gstreamer to send image/jpeg to process decode with VPU on IMX8MP?

Regards

Hi @thepnimit

Did you ever solve this? I am also in need of JPEG encode/decode using VPU.

Thank you!
