The advantage anycodings_slideshow of this method is that you can control anycodings_slideshow which filter goes first ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf "fps=25,format=yuv420p" out.mp4 If your video does not show the frames anycodings_slideshow correctly If you encounter problems, anycodings_slideshow such as the first image is skipped or anycodings_slideshow only shows for one frame, then use the anycodings_slideshow fps video filter instead of -r for the anycodings_slideshow output framerate ffmpeg -r 1/5 -i img%03d.png -c:v libx264 -vf fps=25 -pix_fmt yuv420p out.mp4Īlternatively the format video filter anycodings_slideshow can be added to the filter chain to anycodings_slideshow replace -pix_fmt yuv420p like anycodings_slideshow "fps=25,format=yuv420p". The audio is reversed creating and finally the two streams ( + ) will merge and output as a new file, output.mp3: $ ffmpeg -i input.mp3 -filter_complex "asplit areverse amix=inputs=2" -map "" output.mp3ĭon’t worry if the above code looks intimidating, distinct linear chains are easy once the more you use them and get used to the syntax.See the Create a video slideshow from anycodings_slideshow images – FFmpeg The input.mp3,, will split into a temporary stream. Below is an example of a distinct linear chain.

Below is an example of a linear chain horizontally flipping a video and then inverting the colors: $ ffmpeg -i input.mp4 -vf "hflip,negate" output.mp4ĭistinct linear chains use secondary inputs or create temporary streams before creating the final output. Linear chains are filtering done on the input stream or virtual temporary streams but do not require an additional temporary stream before creating the output file. Linear chains are separated by commas while distinct linear chains are separated by semicolons. There are two types of filter chaining in FFMPEG Linear chains and distinct linear chains. It is possible to apply one filter at a time constantly referencing the last output file but ideally, chains are used to efficiently apply multiple filters. As you use FFMPEG one command might get the job done but at times applying multiple filters to a video is needed.
