Carl Eugen asked you to provide not only the complete command line you tried, but also the complete, uncut console output from the command. Getting back to your question: > how to change the 0x00FF code on the audio part of this movie extract ? > i want to see "mp4a" data instead of 0x00FF > > i have tried to extract audio before > ffmpeg.exe -i video.3gp -c:v copy -c:a aac -strict experimental %dir%\son.aac > -atag mp4a What were you expecting? How did you check the resulting file? What did you get? I can point out several errors at this point (but still want your complete, uncut output!) - The command line element "-atag mp4a" is not interpreted, as you put it after the output file name. Your ffmpeg should have warned you as such: "Trailing options were found on the commandline." - Copying the video stream with "-c:v copy" into an ADTS file (which ffmpeg automatically assumes as format when you give the output file the suffix ".aac") will result in an error, because video cannot be mapped into that file format. You are probably lucky because your 3GP file did not contain video in the first place. Use "-vn" (no video) or just omit "-c:v xxx". - You're not just "extracting" audio, you are converting it. Without your complete, uncut console output, we can't say whether this is a good or a bad idea. Depending on what you were expecting.
