ffmpeg pruduces 0 byte output if build with cmake

[nanake]

use this command ffmpeg -loglevel debug -filter_complex "smptehdbars=size=1280x720:rate=30:duration=10" -c:v libkvazaar -y out.hevc

libkvazaar with cmake, it produce 0 byte output file.

It works fine with autotools.

@fador indeed, cmake missed the cflags -Wa,-muse-unaligned-vector-move.

[Jovasa]

Is this issue still present at the current master?

[nanake]

The issue still persists.

But this build works.

fwiw, for cross compiling, the target os is Windows, not mingw. so, this check if(CMAKE_SYSTEM_NAME MATCHES ".*MINGW.*") won't work.

[Jovasa]

Hopefully this should be fixed in v2.3.1

[nanake]

I can verify this is fixed for me in commit f34f8a7.
