Track layout issues with data track being first

[vish91]

Do we know of any bug where running mediainfo on a track which has data track as first in input source causing mediainfo call to hang ?

e.g

ffmpeg -i CBS_SURVIVOR_3614_3615_HD_R.mov

Making a mediainfo call just runs endlessly and doesn't finish or error

$ mediainfo CBS_SURVIVOR_3614_3615_HD_R.mov

mediainfo --version
MediaInfo Command line,
MediaInfoLib - v23.07

Sample file please. If can not be shared publicly, please send the link to info@mediaarea.net

@JeromeMartinez yeah sure thing.. its a huge file.. so let me try and clip a small sample making sure the layout remains the same or figure out what i can share .

[vish91]

@JeromeMartinez unfortunately can't share the source will have to get permissions from the Studio side etc.

1. I also tried to clip it with ffmpeg and keep same track order but wasn't able to reproduce the issue there.
   Anything from the above output that stands our for you ? or anything we can run internally and share that output ?

2. Apart from that does mediainfo have like a timeout param that we can set so even if the source is bad the process doesn't just hog up resources and we can end it and return back an error or empty resposne ?
