QuickTime Movie Header Atom Poster Time
Hi, Using the latest ffprobe version 4.4 I am trying to print the poster time from the mvhd. Here is the data structure https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/QTF.... As I see from the code in https://github.com/FFmpeg/FFmpeg/blob/f40e9b13554d88cbdd6cd2b4a3da2cbea9590f... poster time is there, but I am not sure of the ffprobe args that will log poster time, current time etc to stdout. I should note that exiftool does log to stdout the poster time. i.e. exiftool POSTERFRAME_YES_995968260_h1.mov | grep Poster Poster Time : 7.32 s How can I have ffprobe also print out the poster time or all the values in the mvhd? Thank you. Bryce Chester Newman | Principal Developer p: +12069255045 |

Nothing is done with that data - it's not exported. I'll send a patch to write many of those fields out as metadata, but I expect that to take some time as many regression unit tests will have to be changed. Regards, Gyan
Hi Gyan, Thank you! Can this patch be included in future stable versions of ffprobe?

All features added to the master branch will make it to a future release. Gyan
Hi, Is there a way I can correlate which version of FFprobe this change the patch might be applied? Thank you.
