I made a bash script that transfers audio or video metadata from one file to another, regardless of media container format, via FFMpeg. My problem is that FFMpeg consistently adds a 'ENCODER' tag.
Example:
Before running through FFMpeg:
File: track01.cdda.flac
Metadata:
ALBUM : Wish You Were Here
ARTIST : Pink Floyd
COPYRIGHT : 1975 Harvest Records
DATE : 1975
GENRE : Experimental Rock
TITLE : Shine On You Crazy Diamond
track : 1
After running through FFMpeg:
File: track01-iphone-alac.m4a
Metadata:
ALBUM=Wish You Were Here
ARTIST=Pink Floyd
COPYRIGHT=1975 Harvest Records
DATE=1975
GENRE=Experimental Rock
TITLE=Shine On You Crazy Diamond
track=1
ENCODER=Lavf55.12.100
So really, I want to either force FFMpeg to not add the 'ENCODER' tag, or I want to strip that tag off afterwards. Is there a way to do this? I really don't want to spend hours trying to compile FFMpeg again on my Pentium 4 HT - the only working computer I have at the moment. I'd prefer not to have to use another program unless it's related enough to FFMpeg or MPlayer/Mencoder that I won't have to install anything new if I have those installed.

The use of –probesize and –analyzeduration help FFMPEG to recognize the audio and video stream parameters of a file, and while they are by no means necessary, their use can help reduce input processing errors, especially when moving across codecs.
-t specifies the duration of the clip (same format). Recent ffmpeg also has a flag to supply the end time with -to . -c copy copies the first video, audio, and subtitle bitstream from the input to the output file without re-encoding them. This won't harm the quality and make the command run within seconds.
FFmpeg is an industry standard, open source, widely used utility for handling video. FFmpeg has many capabilities, including encoding and decoding all video compression formats, encoding and decoding audio, encapsulating, and extracting audio, and video from transport streams, and many more.
ffmpeg is a command-line tool that converts audio or video formats. It can also capture and encode in real-time from various hardware and software sources such as a TV capture card. ffplay is a simple media player utilizing SDL and the FFmpeg libraries.
Old question but in case someone needs it, I found this works to prevent the creation of the Encoder tag, at least on MP4 files.

Doesn't -metadata encoder='my encoder' command-line option work?
