Please help me to process each using one line of ffmpeg (Windows) code to convert all files at once to uncompressed .avi files that are at a pixel dimension of 704x480. This codes is working nice, but I faced that. When I type (y). the output file is remove the past file (input _double_high) and create a new one with the same name. The code doesn't convert all of them. I hope to convert all of them at the same time. Could you help editing this code: forfiles /p 264s /m *.264 /c "cmd /c ffmpeg -f h264 -i @file -vf scale=704*480 input_double_high.avi" Thanks -- View this message in context: http://ffmpeg-users.933282.n4.nabble.com/convert-all-files-at-once-to-uncomp...
