Then, the v4l2loopback kernel module needs to be inserted, since that will be used to make the video stream appear as a camera device (e.g. Sudo apt-get install gphoto2 v4l2loopback-utils I’ve been using OBS to capture videos from the 70D (including audio), which seems to work extremely well, but in principle any V4L2 compatible software should now be able to access the camera.įirst, I had to install a couple of packages:.dev/video2), so that other applications can access it the same way as a normal USB cam. The output of gstreamer is sent to a V4L2 loopback device (e.g.The output of gphoto2 is piped into gstreamer which does some data format conversion.Use gphoto2 to initiate video capture on the camera and receive the data in real time from USB and pipe it onwards via stdout.Connect the Canon 70D to the laptop via USB cable.One drawback to using the 70D this way is that it doesn’t seem to be possible to power it via the USB connector, so you either need to periodically recharge the battery or buy some kind of AC adapter that plugs into the battery compartment (I think devices like this are available, but I haven’t tried any of them). Anyway, I spent a while digging around to figure it, but the solution which finally worked for me (shown below) is basically straight from this post. However, although I think Canon provides some kind of software utility to support this kind of thing in Windows and Mac OS, it wasn’t immediately obvious how to do it in Linux. The quality of video from the 70D is super and it has a USB connector, so I thought this should be possible.
For a while now, I’ve been interested in using my Canon EOS 70D DSLR as a USB camera so that I can record (and potentially live stream) better quality tutorial videos.
