Does anyone have an idea of how I can put an image mask over the video without changing the audio & video codec?
I'm making different media files for testing purposes and I want control over my audio and video codecs used in a A/V container, now I need to put an image mask over a A/V file, without changing the audio and video codec.
ffmpeg -i video.avi -i image.png -filter_complex 'overlay' avi.mkv I can add
-acodec copy but not
-vcodec copy, this gives the error:
Streamcopy requested for output streaam 0:0, which is fed from a complex filtergraph. Filtering and streamcopy cannot be used together.
And when just using the above command FFmpeg encodes my streams to another format (MPEG-4 & MP3)
