libjpeg-turbo on imx7 problem

Contributor II

Hi, I need to install libjpeg turbo on my imx7 board, I am using the CL-SOM-imx7 board but I am compiling  yocto adding the next lines to local.conf:

IMAGE_INSTALL_append +="libjpeg-turbo kernel-modules"

PREFERRED_PROVIDER_jpeg = "libjpeg-turbo"

PREFERRED_PROVIDER_jpeg-native = "libjpeg-turbo-native"

and using:

DISTRO=fsl-imx-x11 MACHINE=imx7dsabresd source -b build-x11

bitbake fsl-image-gui

And then I burn my sd card from the .sdcard file but the files for libjpeg-turbo are not there, so searching in the output I found the compiled lib at:


So, I have copied the files manually to my target and the library is working but the conversion time is not good, I think that may be I am on libjpeg (non turbo) or may be it is because the version is not the later, I had tested the version 9 on a imx6sx with better results.

btw I use the application cjpeg.

So, how can I get installed the libjpeg-turbo in my target at compiling time?

How can I get the latest version?

Could you advice?

Thanks in advance,

Hi Aaron

one can post it on meta-fsl-arm mailing list, so that someone familiar with

software for that board and libjpeg libraries could try to assist you.

Note, i.MX7 and i.MX6SX have not vpu and conversion time may be not good,

depending on algorithm.

Best regards
