Fail to compile with ffmpeg-4.0. *SOLVED*
Added by Peter Christy over 6 years ago
System: Slackware64-current, ffmpeg-4.0
After upgrading to ffmpeg-4.0, tvheadend failed to start. Recompiling the latest git version (cloned today, 12th June) gives the following error:
-------------------------------------------------------------------------------------------------------------------------------------------------
CC src/transcoding/transcode/video.o
src/transcoding/transcode/context.c: In function 'tvh_context_open_filters':

Any fixes?
TIA,

When you build, use make CFLAGS_NO_WERROR=yes. It's a temporary fix, but gets the job done.
YES! That worked, many thanks!
I take it from your comment about a temporary fix that a more elegant solution is in the works?
