Convert SWF to video

i=in.swf; dump-gnash -1 -j 1280 -k 720 -D "${i%.*}".bgra@12 -A "${i%.*}".wav "${i}"
This will dump a raw BGRA pixel stream and WAV which must then be converted to video: ffmpeg -f rawvideo -c:v rawvideo -s 1280x720 -r 12 -pix_fmt bgra -i "${i%.*}".bgra -c:v libx264 -preset veryslow -qp 0 -movflags +faststart -i "${i%.*}".wav -c:a libfdk_aac -b:a 384k "${i%.*}".mp4 ; rm "${i%.*}".bgra "${i%.*}".wav Our example generates an x264/720p/12fps/AAC best-quality MP4. To get dump-gnash, first install the build-dependencies for gnash (this step is OS-specific). Then: git clone http://git.savannah.gnu.org/r/gnash.git ; cd gnash ; ./autogen.sh ; ./configure --enable-renderer=agg --enable-gui=dump --disable-menus --enable-media=ffmpeg --disable-jemalloc ; make

What Others Think

I don't think it likely I'd use this command, but... . You've picked the greedy variable substitution when you need the non-greedy version. X=hello.world.txt; echo ${X%%.*} hello . Whereas you only want to chop off one segment, so you need: X=hello.world.txt; echo ${X%.*} hello.world
