FFmpeg configure options and what do they add

Most external libraries manually turned on configuration time are only actually needed for encoding or certain filters.

Can be removed if format support is not needed

--enable-amf (enabled by default) (needed for AMD hardware encoding)
--enable-schannel (enabled by default) (needed for https support)
- alternative is --enable-gnutls or --enable-openssl but the latter needs --enable-nonfree since it has a license incompatible with GPL
--enable-libilbc (needed for iLBC decoding support)
--enable-libmfx (needed for Intel QuickSync encoding/decoding)
--enable-libopencore-amrnb and --enable-libopencore-amrwb (AMR codecs support)
- FFmpeg has a native decoder for both variants, but missing some features like comfort noise generation
--enable-libspeex (needed for speex support)
--enable-libxml2 (needed for DASH demuxing)
--enable-nvenc (enabled by default) (needed for Nvidia hardware encoding)

Can be removed if encoding for these formats is not needed since FFmpeg has a native decoder for them

--enable-libfdk-aac (High quality AAC encoder that supports LC and HE profiles)
- Needs --enable-nonfree
- FFmpeg's native encoder is considered better or as good from 96kbps onward, but it still has no support for HE profiles
--enable-libgsm (GSM encoder)
--enable-libkvazaar (HEVC encoder)
--enable-libmp3lame (MP3 encoder)
--enable-libopencore-amrnb (AMR Narrowband encoder)
--enable-libopus (Opus encoder/decoder)
--enable-libsnappy (Snappy compressor needed for Hap encoding)
--enable-libtheora (Theora encoder)
--enable-libtwolame (MP2 encoder)
--enable-libvo-amrwbenc (AMR Wideband encoder)
--enable-libvorbis (Vorbis encoder)
- consider using --disable-encoder=vorbis if using this since FFmpeg's native encoder is shit
--enable-libvpx (Google VP8/VP9 encoder)
--enable-libwebp (WebP encoder)
--enable-libx264 (H.264/AVC encoder)
--enable-libx265 (HEVC encoder)
--enable-libxavs (XAVS encoder)
--enable-libxvid (MPEG-4/XviD encoder)
- FFmpeg's native mpeg4 encoder is high quality too so this isn't needed

All can be removed from ffmpeg_options.txt if not needed

--enable-chromaprint (chromaprint muxer)
--enable-cuda-sdk (scale_cuda filter)
- needs --enable-nonfree, MSVC 2015, and CUDA SDK installed to compile and run
--enable-frei0r (frei0r filter)
--enable-libass (ass and subtitles filters)
--enable-libbs2b (bs2b filter)
--enable-libebur128 (loudnorm filter)
--enable-libfreetype (drawtext filter)
- --enable-fontconfig to enable font fallback and font option
- --enable-libfribidi to enable text_shaping option (needed for bidirectional text)
--enable-librubberband (rubberband filter)
--enable-libtesseract (ocr filter)
--enable-libvidstab (vidstabdetect and vidstabtransform filters)
--enable-libzimg (zscale filter)
--enable-libmysofa (sofalizer filter)
--enable-libbluray (bluray protocol)
--enable-librtmp (rtmp protocol)
- FFmpeg has native support for the same protocols as librtmp
- native rtmp(t)e needs --enable-gmp or --enable-gcrypt if using GnuTLS or SChannel
--enable-libssh (sftp protocol)
--enable-decklink (decklink IO device)
--enable-libcaca (caca output device)
--enable-libcdio (libcdio input device and Audio CD support in mplayer and mpv)
--enable-opencl (enables opencl optimizations in deshake and unsharp)
--enable-opengl (OpenGL output device)
--enable-sdl2 (SDL output device and ffplay.exe)
- Enabled by default, needs --disable-sdl2 or --disable-ffplay to be disabled

All can be removed from ffmpeg_options.txt if not needed

All can be removed from ffmpeg_options.txt if not needed

--enable-libflite (flite source filter)
--enable-libopenh264 (alternative h264 encoder/decoder)
--enable-libopenjpeg (JPEG 2000/J2K video support)
- FFmpeg has a native decoder and encoder
--enable-libsoxr (alternative resampler engine for swresample)
--enable-libwavpack (alternative WavPack encoder/decoder)
- FFmpeg has a native decoder and encoder but is probably slower
