libVLC on Ubuntu - No package 'libavcodec' found
Posted: 26 Jun 2020 08:47
Hi!
For a few days I've been trying to build libVLC for Android, unfortunately without any success.
I'm using an Ubuntu 20.04 live usb, and have been following instructions from https://wiki.videolan.org/AndroidCompile/
After solving many other issues, now I'm stuck at missing libavcodec problem.
The result of the is as follows:
From CMakeError.log I get
But I guess this one is solved by -mfpu=neon -mfloat-abi=softfp
I don't understand why libavcodec cannot be found. I've installed it separately using
and when I run I get 58.54.100
I've exported PKG_CONFIG_PATH to (this is where my libavcodec is located), but still I get this info that No package 'libavcodec' found
Any hint what may be the problem here? I'm rather a Ubuntu noob, so please use simple language
