JPEG parameter struct mismatch

Autonomous Machines Jetson & Embedded Systems Jetson Xavier NX

Hi guys,

I have an issue when trying to use nvjpegenc from my C++ application.
When I run the app I receive immediately: “JPEG parameter struct mismatch: library thinks size is 584, caller expects 728”

But, when I ran the same pipeline from the same Nvidia jetson NX (JP 4.6) Terminal it works fine!

gst-launch-1.0 nvarguscamerasrc ! ‘video/x-raw(memory:NVMM), width=1920, height=1080, format=NV12’ ! nvjpegenc ! filesink location=test.jpg

Any thoughts?

Hi,
Please build the C++ application with the lib:

/usr/lib/aarch64-linux-gnu/tegra/libnvjpeg.so

And try again.

Hi,

I built the app with the library but it will won’t work on runtime. same error.
Here is my CMake link:

find_library(NVJPEG_LIBRARY
NAMES nvjpeg
HINTS /usr/lib/aarch64-linux-gnu/tegra)

if(NVJPEG_LIBRARY)
message(STATUS “Found NVJPEG library: ${NVJPEG_LIBRARY}”)
else()
message(FATAL_ERROR “Could not find NVJPEG library”)
endif()

Link the library to your target

target_link_libraries(Chimera ${NVJPEG_LIBRARY})

cmake print is: – Found NVJPEG library: /usr/lib/aarch64-linux-gnu/tegra/libnvjpeg.so

Hi,
Another possibility is the app is linked to both libnvjpeg.so and libjpeg.so. Please check this and remove linking to libjpeg.so.

Hi,

You are right, I have a link to libjpeg.so as well, but I can’t remove it because I use opencv in my code and it depends on it.

libnvjpeg.so and libjpeg.so can’t be linked together?
