Copying Audio Stream Results in Different Output

Post by vandalay22 » Wed Nov 06, 2019 9:37 pm

I have a video file from a ProRes recorder (Odyssey 7Q+) and when I copy an audio stream to a new file, ffmpeg seems to be changing the audio the codec. Also, MediaInfo also says the original audio is signed, and the new file audio is unsigned.

I am using:
ffmpeg i Video1.mov -map 0:6 -c copy New video.mov

ORIGINAL AUDIO:
Audio: pcm_s32be (lpcm / 0x6D63706C), 48000 Hz, stereo, s32, 3072 kb/s (default)

COPY AUDIO:
Audio: pcm_s32be (in32 / 0x32336E69), 48000 Hz, stereo, s32, 3072 kb/s (default)

Any help is appreciated!
