Body: <p>I am trying to add chapters to a .mp4 file.
  When I tried extracting the metadata using the following command:</p>
  <p><code>ffmpeg -i INPUT.mp4 -f ffmetadata FFMETADATAFILE.txt</code></p>
  <p>I got an output file as follows:</p>
  <pre><code>;FFMETADATA1
  major_brand=mp42
  minor_version=0
  compatible_brands=isommp42
  encoder=Lavf60.15.100
  </code></pre>
  <p>So now I try to add some chapters as such</p>
  <pre><code>[CHAPTER]
  TIMEBASE=1/1000
  START=0
  END=424510
  title=mytitle1
  
  [CHAPTER]
  TIMEBASE=1/1000
  START=424511
  END=941600
  title=mytitle2
  
  [CHAPTER]
  TIMEBASE=1/1000
  START=941601
  END=1227260
  title=mytitle3
  </code></pre>
  <p>I use the <code>ffmpeg -i INPUT.mp4 -i FFMETADATAFILE.txt -map_metadata 1 -codec copy OUTPUT.mp4</code> command to encode the metadata to my video file, and for some reason I only ever get 'Chapter 0', 'Chapter 1', and 'Chapter 2'.</p>
  <p>I tried using the <code>-map_chapters 1</code> argument as well but results have been unchanged.</p>
  <p>I am using the <code>Latest Auto-Build (2023-10-14 13:02)</code> Windows build by BtbN. Thanks in advance for the help.</p>

  (Asked by: username_0 on 2023-10-15)
  
  I am trying to add chapters to a .mp4 file.

  `ffmpeg -i INPUT.mp4 -f ffmetadata FFMETADATAFILE.txt`
  
  I got an output file as follows:

  I use the `ffmpeg -i INPUT.mp4 -i FFMETADATAFILE.txt -map_metadata 1 -codec copy OUTPUT.mp4` command to encode the metadata to my video file, and for some reason I only ever get 'Chapter 0', 'Chapter 1', and 'Chapter 2'.
  
  I tried using the `-map_chapters 1` argument as well but results have been unchanged.
  
  I am using the `Latest Auto-Build (2023-10-14 13:02)` Windows build by BtbN. Thanks in advance for the help.

  Turns out the latest version by BtbN and gyan.dev **does** have an issue, because the chapters encoded just fine when I used the version 5.1.2 build by gyan.dev.
  
  I previously tried using the release version 6.0 but it had the same problem, so the solution is to simply use release version 5.1.2.
