Resolve video playback issue on linux by bundling libavformat and so on with the package

Tested on Ubuntu 20.04 and Ubuntu 19.10 with lazer version ≥ 20191113

Simply copy libavcodec.so.58 , libavformat.so.58 , libavutil.so.56 and libswscale.so.5 into “AppDir/usr/lib/<arch>-linux-gnu/” then rename them to the correct filename.

On ubuntu 20.04 x86_64(64 bit), execute the following commands to copy:

cp /usr/lib/x86_64-linux-gnu/libavformat.so.58 ./libavformat.so &&cp /usr/lib/x86_64-linux-gnu/libavcodec.so.58 ./libavcodec.so &&cp /usr/lib/x86_64-linux-gnu/libavutil.so.56 ./libavutil.so &&cp /usr/lib/x86_64-linux-gnu/libswscale.so.5 ./libswscale.so

I created the symlink libavformat.so , libavutil.so , libavcodec.so and libswscale.so to their origin libs (libavformat.so.58 , libavutil.so.56 , libavcodec.so.58 and libswscale.so.5) then run lazer , the problem disappeared.

I tried a few versions available and found none that would reliably work cross-distro. We’d likely have to build our own.
