No mdata with Canon EOS RP image files about canon_cr3 HOT 5 CLOSED

use https://github.com/lclevy/canon_cr3/blob/master/parse_cr3.py instead with extract flag. the Lib version is not finished. crx data can not be uncompressed by my tool as compression scheme is unknown.

Thank you for your answer.

Surprisingly, using the sample images on this repository (e.g. samples/IMG_0482_raw.CR3), I can extract some data in the mdat. It seems that the samples were taken with a Canon EOS R and not RP.

Ok, i'll check that

should be fixed now

Hi Laurent,
Thank you for the update. May I suggest the following correction:

def stsz(self, d, l, depth):
        version = self.get_long_be(d, 0)
        if l==0x14:
          size = self.get_long_be(d, 4)
          count = self.get_long_be(d, 8)
        else:  #0x18
          size = self.get_long_be(d, 12)
          count = self.get_long_be(d, 8)
        return size

Replace getLongBE()with self.get_long_be().
