Audio stream not detected in large file (24h)

[sandersaares]

Using v17.12 GUI, the following file does not show an audio stream: https://media.axprod.net/TestPattern/24h_TestPattern_B_420.mp4

This content is 24 hours long, which might be a contributing factor. Cutting the same content down to 1h makes the audio stream info show up.

Compare to FFprobe, which does show the audio steam:

With CLI, I see something like an error message at the head of the output:

Definitely a problem somewhere, weird that the 24-hour video is detected but not the audio part.
