This may not be due to ffmpeg itself, but I would appreciate some help. Configure says that pkg-config can’t find fontconfig.pc, but it seems to be in the PKG_CONFIG_PATH. # ./configure --cc=/usr/bin/gcc \ --prefix=$TARGET \ --pkg-config-flags="--static" \ --extra-cflags="-I/usr/local/include"

I’ve been building ffmpeg on a Mac since 2017, and this is the first time I’ve run into this kind of problem. I pulled the latest git head today. After getting all the dependencies set up, I configure ffmpeg successfully like this: ./configure \ --prefix=${TARGET} \

Re: [FFmpeg-user] Buind ffmpeg-3.2.2 on Mac OS X

Moritz pinpointed the problem to missing/lost x264.h. In my mac system that is at /usr/local/include, so if you can find it, you could perhaps move it there. If that doesn’t work, I second the suggestion of Luke to use homebrew to install a lot of these dependencies and such. It works well

Oh, if you need to remove the metadata, assuming the rotation metadata belongs to the stream, add -map_metadata:s -1 to the command, or just -map_metadata -1 to remove all metadata, stream or global. On Wed, Dec 14, 2016 at 4:05 PM, Jim Worrall <conioph...@gmail.com> wrote: > I do

I’ve been using ffmpeg with libx265 to transcode Star Wars blurays to smaller files. Episodes 1 and 2 went perfectly. I made screenshots from identical points and they were virtually indistinguishable. When I did Episode 3, I noticed that the screenshots from the transcode were darker than
