Comment:

 Replying to [ticket:6421 sandersd]:

 For future tickets: Please remember to always provide an as-simple-as-
 possible ffmpeg command line that allows to reproduce the issue together
 with the complete, uncut console output, do not report issues against
 ffprobe if they are reproducible with ffmpeg.

 > In the three cases reported above (7001A.mp4, MVI_5623.mp4, and
 nonFormattedMetaData.mp4), the first frame in presentation order is not
 the first frame in decode order. The metadata correctly records this.
 However, FFmpeg is reporting that the first frame in decode order is at
 time 0

 > (therefore the first frame in presentation order has a negative
 timestamp).
 Why do you think this is an issue?

 I only found 7001A.mp4 and nonFormattedMetaData.mp4, where can I get
 MVI_5623.mp4?

 I cannot reproduce negative timestamps with nonFormattedMetaData.mp4, if
 there is an issue for 7001A.mp4, it is a regression since
