Camera & Video Support?

[jtkeyva]

Does the rpi camera module or a usb camera work with this? Can it record and playback videos at 4k?
thanks!

I started a private project to port
https://github.com/caprica/picam
https://github.com/caprica/picam-native
to dart using FFI. But this port will only support still images.

Video playback works via omxplayer_video_player, but there's no plugin for camera playback right now.

But I think it's possible to get working with a workaround. On newer raspbian, the pi cam or any other camera should be present as a /dev/video0 file. Some other people tried to get omxplayer to playback that file: https://www.raspberrypi.org/forums/viewtopic.php?t=69322

So if we take the first one as an example:

mkfifo /tmp/out.raw
mplayer tv:///dev/video0 -dumpstream -dumpfile /tmp/out.raw

And then, instead of invoking omxplayer with omxplayer <some path or URL>, you initialize your VideoPlayerController with:

VideoPlayerController.file("/tmp/out.raw")

This is not particularly optimal though, maybe there's delay or high CPU usage because so much memory will be copied, so it'd still be cool to have a real camera plugin

Btw, omxplayer_video_player is just a backend of video_player. So for docs on how to use it to play video you actually need to look at the video_player package, or you use some higher level video player like Chewie :)
