To convert a .caf file to an .opus file without re-encoding the content, use the following command:
ffmpeg -i input.caf -c copy output.opusReplace input.caf with the name of your .caf file, and output.opus with the desired name of the .opus file. The -c copy option tells FFmpeg to copy the existing audio codec without re-encoding it.
Step 4: Verify the Conversion
To verify that the conversion was successful, you can use a media player that supports .opus files, or you can use the ffprobe command, which is included with FFmpeg:
ffprobe output.opusYou should see output similar to the following:
Input #0, opus, from 'output.opus': Duration: 00:00:03.04, bitrate: 128 kb/s Stream #0:0: Audio: opus, 48000 Hz, stereo, fltp- FFmpeg is a powerful, open-source multimedia framework that can handle a wide variety of audio and video formats.
