[FFmpeg-user] Compiling ffmpeg with an output device (Blackmagick Decklink)

[David Di Biase]

Carl, my apologies for not including config.log. I've attached a copy here.
I also managed to get through most of the issues I was having however I
have one final issue regarding running the mak file. Here's the command I'm
using:

*cd ~/ffmpeg_sources && *
*wget -O ffmpeg-snapshot.tar.bz2
https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
<https://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2> && *
*tar -xjvf ffmpeg-snapshot.tar.bz2 &&*
*cd ffmpeg && *
*PKG_CONFIG_PATH=$PKG_CONFIG_PATH:"$HOME/ffmpeg_build/lib/pkgconfig"
./configure --prefix="$HOME/ffmpeg_build" --pkg-config-flags="--static"
--extra-cflags="-I$HOME/ffmpeg_build/include*
*-I$HOME/Decklink" --extra-ldflags="-L$HOME/ffmpeg_build/lib*
*-L$HOME/Decklink" --extra-libs="-lpthread -lm" --bindir="$HOME/bin"
--enable-gpl --enable-version3 --enable-nonfree --enable-libfdk_aac
--enable-fontconfig --enable-libfreetype --enable-libmp3lame
--enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264
--enable-libx265 --enable-decklink --enable-librtmp --enable-openssl &&*
*PATH="$HOME/bin:$PATH" make &&*
*make install &&*
*hash -r*

At the tail of that command as it's confirming the build files I get the
following:

*License: nonfree and unredistributable*
*config.h is unchanged*
*config.asm is unchanged*
*libavutil/avconfig.h is unchanged*
*libavfilter/filter_list.c is unchanged*
*libavcodec/codec_list.c is unchanged*
*libavcodec/parser_list.c is unchanged*
*libavcodec/bsf_list.c is unchanged*
*libavformat/demuxer_list.c is unchanged*
*libavformat/muxer_list.c is unchanged*
*libavdevice/indev_list.c is unchanged*
*libavdevice/outdev_list.c is unchanged*
*libavformat/protocol_list.c is unchanged*
*ffbuild/config.sh is unchanged*
*ffbuild/config.mak:6: *** missing separator.  Stop.*

I attempted tracking down the issue and found this ticket on the ffmpeg
tracker: https://trac.ffmpeg.org/ticket/1209. I'm not using the git pull,
instead I'm just unpacking the source tar.

Hopefully someone has experienced this before and knows where I should look
for a solution.
