Build problem

[mincequi]

Hi, thanks for your feedback.
What‘s your build environment?
Are there more logs you can provide?

[mincequi]

Apparently, there had been issues with the Debian scripts. I did a quick fix. Please check again :)
Thanks a lot.

[mincequi]

Could you follow the non-debian Installation steps?
Using cmake (not dpkg-buildpackage)?

[macek-jm]

ok now we can see much more

Thanks again for testing.

Your are using an old kernel version(4.19.50-v7), that does not match you libavcodec and/or raspi firmware installation. So, you will also get this error when using libavcodec in another application.
Consider upgrading your kernel to at least 4.19.73.

Btw:
Why do you compile yourself? There are binary packages available for pi (arm).

[macek-jm]

Yeah, now is ok. Was my oversight.

i compile by myself for self-progress ;)

thnx a lot.
