Downloading .LRV and .GPR files from gopro camera #24

Open yuval-herman opened 3 years ago

yuval-herman commented 3 years ago

Currently the RPD software does not handle lrv and gpr files and writes a line in the error log. Is it possible to allow downloading unrecognized files in the preference menu? or even better to download them to another folder, the same way it is possible to download raw and jpg files to different folders?

I don't know what a LRV or GPR file is. I don't own a GoPro camera. Please either link to the documentation that describes exactly the their purpose, or describe it yourself. Without this information there is nothing I can do.

I have no plans to have Rapid Photo Downloader download unrecognized files.

yuval-herman commented 3 years ago

I see, the LRV extension stands for Low Resolution Video and is just a preview of the captured video. The LRV file is actually of less importance and I understand if you don't want Rapid Photo Downloader to download it. The GPR file however stands for General Purpose Raw and is an extension of the DNG format for action cameras. You can find more information about it here as well as it's GitHub repository here.

Thanks for that. Do both Exiv2 and ExifTool read and correctly report the GPR file metadata? At least one of these tools must be able to read the image metadata correctly. Please test this and carefully verify the results are correct.

I would happily test for that but I'm not going to be in front of a computer for the next week at least... In the mean time if you want to test that yourself there are GPR file samples in the GPR repository, as for LRV files, it's no big deal so when I get back I will do whatever tests you need or provide sample files. Also for when I get back home in case that you can't test that yourself, what exactly do you mean by reading the metadata correctly? I know exiftool can read GPR metadata no problem as I have used it in my projects before.

I just downloaded exiftool 12.25 (current version) and it fully supports the GPR file to read the metadata. Sample output from exiftool below:

Please consider one of the following:

  1. Submitting a pull request that contains the code that addresses the issue, preferably by relying on Exiv2 before ExifTool (Exiv2 is much faster).
  2. If you can't write the required code, sponsoring a developer to do the work for you.

Thanks.

Hello, would you have an example for another raw import that could serve as a base to implement the downloading of the .gpr files ?
