Auto Renaming Prompting to rename any input file (s) with non-ASCII filenames to be compatible with command-line processor. Drag & Drop Drag and drop your file (s) from your system to be processed quickly. It seems that 1 file has 2 input formats (1 m4a, 1 image2), I think ffmpeg should be able to do the same thing by itself instead of using a separate tool to add cover image, but I haven't figure out how. FFmpegGUI currently supports File, DirectShow, Blackmagic Decklink, NewTek NDI or URL inputs.

I use ffmpeg -i track.flac track.m4a to convert between these two formats but I notice that the resulting ALAC files are much smaller than the original ones. Stream #0:0(und): Audio: aac (mp4a / 0圆134706D), 44100 Hz, stereo, fltp, 238 kb/s (default) Both ALAC and FLAC are lossless audio formats and files will usually have more or less the same size when converted from one format to the other. I thought about writing her some batch scripts, but I'm assuming someone knows of a good Windows GUI front end. I tried mp4art, after adding the cover, the information from FFmpeg is like this: stream 0, timescale not set I use ffmpeg in Linux in the command line (and love it) but I've got a windows only client looking for a good video encoder.

Mp4art from mp4v2 can also do this: mp4art -add cover.jpg track.m4a
