[BUG?] Black bar detection & video analysis does nothing

(1/2) > >>

mattkhan:
for a small no of files in my library, these functions do nothing and return v quickly. The corresponding items are playable. The logs suggest the task does execute, for exmaple

in this case, Video Crop remains empty after execution.

Hendrik:
If its all Blu-ray structures, I wonder if its selecting a m2ts file thats just too short or something like that. I'll add some logging to tell us which file it picked, maybe that'll shed some light.

mattkhan:
not sure if related but where is HDR Average & Peak Luminence coming from? is it the on disc metadata for MaxFALL and MaxCLL? just wondering why some tracks have blanks in these fields

Hendrik:
Yes, average and peak is MaxFALL and MaxCLL respectively. Not all files have it. Its a bit more on the optional side of metadata, and JRVR for example doesn't use it at all for tone mapping (although it does pass it to the display if pass-through is on).

mattkhan:
I spent some time working through the "bad" files and eventually I worked out that a number of them actually were bad for various reasons

1) paths were wrong due to something that looks like a partial move done by MC, the index.bdmv was in one dir and the content was in another
2) some files which were not 3d but were flagged in MC as 3dbdmv
3) assorted DVDs (which I converted to mkv and reimported)

after all this, I am left with just 2 BDs, both of which play just fine and seem complete on disk. It would be nice to get them scanned and/or find out what's wrong with it but otherwise I guess I can probably just reimport as mkv.
