(Copy-pasted from Doom9, as I think it might be easier to track it here.)
When loading an input file, it shows two "delays" for any track.
According to https://sourceforge.net/p/gmkvextrac...read/ee13f7e1/ the first delay is relative to 0 timestamp and the second one is relative to the video.
The original comment only mentions audio track, so what about the video track?
Is the second delay still relative to the video (itself), or to the audio?
Either way, it doesn't seem to match with the behavior.
I made two videos to test: one with audio delayed for 2sec, one with video delayed for 2sec.
The first one (audio delay):
The video's second delay says "0ms", so it means it's NOT delay relative to audio, because otherwise it would be "-1978ms".
The second one (video delay):
Now, here video's second delay says "2000 ms", which means it's indeed relative to the audio. This is inconsistent with example 1.
Summary:
In both cases, the first delay of video track is consistently shows the delay relative to 0 timestamp.
In both cases, the first delay of audio track is consistently shows the delay relative to 0 timestamp.
In both cases, the second delay of audio track is consistently shows the delay relative to the video track.
However, the second delay of video track is inconsistent, it shows the delay relative to the audio in one, but not in another (it is not consistently relative to the video, either.)
