Take for example a signal graph that looks like this: run()) API reference Complex filter graphsįFmpeg is extremely powerful, but its command-line interface gets really complicated rather quickly - especially when working with signal graphs and doing anything more than trivial. Or if you prefer a fluent interface: pythonimport ffmpeg( ffmpeg. Quickstartįlip a video horizontally: pythonimport ffmpegstream = ffmpeg.input('input.mp4')stream = ffmpeg.hflip(stream)stream = ffmpeg.output(stream, 'output.mp4')n(stream)
ffmpeg-python works well for simple as well as complex signal graphs. There are tons of Python FFmpeg wrappers out there but they seem to lack complex filter support. vf/-af/-filter and -filter_complex cannot be used together for the same stream.Python bindings for FFmpeg - with complex filtering supportįfmpeg-python: Python bindings for FFmpeg Stream #1:0: Video: png, rgba(pc), 200圆6, 25 tbr, 25 tbn, 25 tbcįiltergraph 'scale=w=trunc(iw*0.5/2) 2:h=trunc(ih0.5/2)*2' was specified through the -vf/-af/-filter option for output stream 0:0, which is fed from a complex filtergraph.

I am basically trying to do the same command from from this gist.
The video should render with the watermark png onto it. outputOptions ( '-pix_fmt yuv420p' ) Expected results
