This build of `ffmpeg` will support splitting previoiusly-produced webm video into png frames: ```sh $ ffmpeg -i video.webm frames%03d.png ``` This patch: - adds `matroska` demuxer and `libvpx` decoder to parse webm videos - adds `png` encoder and `image2` muxer to output frames - enables `zlib` since its a dependency for png This increases the build size on Mac from 3.1MB unzipped to 3.3MB unzipped.
