I didn't know.
Thanks for that. I found it on FSL_MIRROR, and this time it seems that the recipe name matches the package name. I will try to build it with LTIB. I noticed there several changes comparing with gst-fsl-plugins-3.5.7-1.0.0.
I was not able to find release notes inside the pkg, I was used to read the pdf files in docs directory, but now there is just eula.txt there, any hints about where to look for?
