Why doesn't this pipeline work? NvMMLiteBlockCreate : Block : BlockType = 279

Hey, Can jason@jaylin.com.au reach you?

yes

Update the offline discussion
“Could you help to replace the lib(seeing attachment) and create a simple pipeline with nvv4l2decoder ! fakesink and share me the result, would be better if you can capture the runtime log.”

Pls share your result on the topic again.

Hi @bcao - I’m unable to find the existing lib ‘libnvmmlite_video.so’ on my jetson nano. Therefore I can’t replace it with the copy you sent.

Where should I place this lib to test or is it not for a nano and meant for xavier or something else???

could you check the dir /usr/lib/aarch64-linux-gnu/tegra/ ?

ok found the file in /usr/lib/aarch64-linux-gnu/tegra/ but don’t know why “find” won’t find it.
Now if I replace it with the version you sent me (which is much larger) then everything in deepstream just hangs. For example the deepstream-app hangs with this output:

Hey customer,
I would suggest to wait for DS 4.0.2 release 2 weeks later.
