  Audio Copy Results in Different Audio

  Posted by Grant Mcnair on November 6, 2019 at 12:11 am

  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 a the audio properties, including the codec. MediaInfo also says the original audio is signed, and the new audio is unsigned.

  ffmpeg i Video1.mov -map 0:6 -c copy New video.mov
  Original Audio (stream 0:6): pcm_s32be (lpcm / 0x6D63706C), 48000 Hz, 2 channels, s32, 3072 kb/s (default)

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

  Any help is appreciated!
