segfault with h,264 encode

[david3a]

tried the following, logging turned on after seeing seg fault

./ffmpeg -loglevel debug -f lavfi -i testsrc2=s=1920x1080,format=nv12 -c:v h264_rkmpp -b:v 4M -profile:v high -level 4.1 -g:v 100 -vframes 5000 -y tmp.mp4

gets this, any ideas?

@david3a Please build install the latest MPP runtime and try again.

https://github.com/nyanmisaka/ffmpeg-rockchip/wiki/Compilation#important

Important

Make sure you have built and installed the latest MPP runtime and headers. Otherwise undefined behavior may occur, such as segmentation fault. Be careful if you use MPP deb packages from a vendor/BSP image, these packages are likely to be out of date.

[david3a]

looks better, though I had done that, is had to change

make install

to

sudo make install

[nyanmisaka]

Any other issues after running with sudo?
