Thanks for the succinct explanation of the problem, a lot of this now falls into place and makes sense, but something still doesn't add up here. I have tried approaching the Cygwin mailing lists with this but the response I got was that Cygwin wasn't the problem, but maybe coming to them with a more specific solution will change that. Interesting, I suppose I assumed that FFmpeg can only build from the features of the sources that it builds from - my knowledge of compiling isn't too great. FFmpeg likely will hit the exact same roadblock, making it imperative on Cygwin to fix their header if you want this to be possible without editing stuff yourself. The proper fix is that Cygwin's windows.h header needs to include wtypes.h a stop-gap would be to edit x264's local input/avs.c and insert the wtypes.h include before the include for extras/avisynth_c.h before you compile it. The problem lies in Cygwin's w32api headers not including wtypes.h in the correct place. The SO answer by Missy tells you exactly what's needed to make x264.exe compile with AviSynth under Cygwin. Making AviSynth enabled in FFmpeg is its own option given to FFmpeg's configure script, -enable-avisynth. It does absolutely nothing to libx264 (which has no input modules), FFmpeg uses libx264, and FFmpeg doesn't care at all whether x264's CLI program has AviSynth enabled. disable-avs is what x264's configure script uses to disable AviSynth support in the x264 CLI program. You're confusing which parts make which input active and for which program. What's the problem here and how can I solve it? The errors go away and the compilation works when I include -disable-avs, but I don't want the version of FFmpeg that I build to come without AVS/Avisynth support.
#HOW TO INSTALL FFMPEG CYGWIN WINDOWS#
The error immediately before the one above is the HMODULE error here:Īnd in that question the OP and another answer are trying to follow the very same guide I am while using Cygwin on the same 64-bit Windows 7. bindir="/usr/local/bin" -enable-static -enable-pic & PATH="usr/local/bin:$PATH" make -j4 & make installīut at the configure stage of this command, I get a few errors and lots of warnings, but the final error is this one: & cd x264 & PATH="/usr/local/bin:$PATH" PKG_CONFIG_PATH="/ffmpeg_build/lib/pkgconfig". So I'm now trying to build x264 from source with the following command:Ĭd /ffmpeg_sources & git -C x264 pull 2> /dev/null || git clone -depth 1
I've sorted many of the dependencies to get it to work on Cygwin, and thankfully I didn't need to build most of the packages in that guide from source because they were included in the Cygwin repository, but there are 2 or 3 that are not, including x264 and x265.
I'm trying to follow the FFmpeg wiki's guide here to build FFmpeg from source with the most superior codecs it can make use of, like libfdk-aac and libopus:
