Transferring files off of most cameras to a Linux computer isn't all that
difficult. The exception is my GoPro Hero 4 Black. For 4th of July week I took
a bunch of video with the GoPro, approximately 20 MP4 files, about 3GB each.
The annoying thing about the GoPro's USB interface is you need additional
software to download everything through the cable. The camera doesn't just show
up as a USB filesystem that you can mount. The GoPro does have a micro-SD card
but I was away from home and didn't have any dongles or adapters. Both of these
solutions also mean taking the camera out of its waterproof case and off of its
mount. So here's what I did.
GoPro cameras, after the Hero 3, can open up an ad-hoc wireless network that
lets you browse the GoPro's onboard files through an HTTP server. This means
you can open your browser and scroll through the files on the camera at an
intranet address, `10.5.5.9`, and download them one by one by clicking every
link on every page. If you have a lot of footage on there it kinda sucks. So, I
opened up the manual for `wget`. I'm sure you could get really fancy with some
of the options but the only thing I cared about was downloading every single
MP4 video off of the camera, automatically. I did not want to download any of
the small video formats or actual HTML files. Here's what I used:
```sh
wget --recursive --accept "*.MP4" http://10.5.5.9:8080/
```
This tells `wget` to download all of the files at the GoPro's address
recursively and skips any that don't have the MP4 extension. Now I've got a
directory tree with all of my videos in it. And the best part is I didn't have
to install the dinky GoPro app on my laptop. Hopefully this helps if you're
looking for an easy way to migrate lots of footage without manually clicking
through the web interface or installing additional software. The only downside
is if you're moving a whole lot of footage, it's not nearly as quick as just
moving files off the SD card. So I'd shoot for using the adapter to read off
the card first and only use this if that's not an option, such as when the
camera is mounted and you don't want to move it.
Some things I would like to change/add:
- Download all image files as well; should be easy, just another `--accept`
- Initiate parallel downloads
- Clean up the directory afterwards so I just have one level of depth
I could probably write a quick and dirty shell script to do all of this for me
but I use the camera so infrequently that it's probably not even worth it.
