I'm trying to convert a file using the following command
ffmpeg.exe -i .\kme9le9xeaa31.png -c:v apng .\kme9le9xeaa31.png.cpy
But ffmpeg yields the following error that it is unable to determine output file format
Unable to find a suitable output format for '.\kme9le9xeaa31.png.cp'
.\kme9le9xeaa31.png.cp: Invalid argument
Considering that filename is just metadata and should not be taken at face value, should ffmpeg not interpret it? If not, how do you disable such behavior?
