@tee thank you, updated.

switch to using untrunc-anthwlock-cli-git which is an improved and updated fork https://github.com/anthwlock/untrunc.

The PKGBUILD fails to build libav:

libavfilter/avfilter.c: In function ‘ff_filter_frame’:

It seems we need this patch[1].

libav no longer builds:

./libavcodec/x86/mathops.h: Assembler messages:  
./libavcodec/x86/mathops.h:125: Error: operand type mismatch for `shr'  
./libavcodec/x86/mathops.h:125: Error: operand type mismatch for `shr'  
./libavcodec/x86/mathops.h:125: Error: operand type mismatch for `shr'

There is issue in line 2 in prepare():

tar xf ../libav-${libav_version}.tar.gz

In other words, unpack .tar.gz, not .tar.xz.

@SR-G replaced the libav URL with the source package from their github mirror:

I fear it's not working anymore, as the online libav URL is not accessible :(

thanks for commenting your PKGBUILD fix, @Qwerty-Space.
