 Summary of the bug:

 When processing a video with an audio track with fpcm encoding (produced
 via QuickTime), ffmpeg always produces the following error

 {{{
 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x123104280] Unsupported 'chnl' box with
 version 1, flags: 0error reading header
 [in#0 @ 0x6000018e4000] Error opening input: Invalid data found when
 processing input
 Error opening input file AssetVideo_original.mov.

 }}}

 How to reproduce:
 1. Open a video with an audio track in QuickTime
 2. Trim the video using the built-in QuickTime tools
 3. Save the video
 4. The resultant video has an fpcm Audio codec
 5. Attempt to load the video using `ffmpeg -i [PATH TO VIDEO]`
 6. FFMPEG produces the error message described above
