Apple ProRes / apco support..? #75

Closed jahudka closed 3 years ago

jahudka commented 3 years ago

Hi, I have a bunch of files *_ftyp.mov files restored by photorec which I'm trying to recover using untrunc. I also have a sample file from the same camera; ffprobe reports that this file contains an Apple ProRes 422 video track (the codec tag string is apco). untrunc gives me this:

Info: unknown track 'apco' found -> fallback to dynamic stats
Error: bad track: 'apco'

Am I correct in assuming this means that the Apple ProRes codec isn't supported by untrunc? If I am, is there any chance that support could be added? I'd send the files, but they're both almost 20GB..

See #69

The reason I didn't merged it yet is that it I had to increase the upper sample-size limit to 16mb, which adds more false positives for some files. I plan to replace this strict upper limit with a more dynamic one, which takes the average sample-size of the reference file in account.
