Kajan001 0 Posted March 28 I have a tinkerboars r2 (and a TB 2s) with recommended OS. I have attached a picamerav2 (8MP imx219) and it works with gstreamer but I have yet to learn that. I cannot get ffmpeg working, I just get the message: [video4linux2,v4l2 @ 0x810f7610] Not a video capture device. /dev/video1: No such device Using: ls /dev/video* I get: /dev/video0 /dev/video1 /dev/video2 /dev/video3 /dev/video4 so clearly the camera is recognised by the system Has anyone got ffmpeg working on TB os?

tooz 20 Posted March 28 hello @Kajan001, which command did you execute for using the cameras? Share this post Link to post Share on other sites
tooz 20 Posted March 29 somebody reported the issue to ffmpeg: [FFmpeg-user] Can FFmpeg Record Video On Linux Using V4L2 in V4L2_CAP_VIDEO_CAPTURE_MPLANE Mode? Looks that the mplane format is currently not supported when capturing from a v4l2 device at the moment. If you have time, please create a ticket on https://trac.ffmpeg.org/report Share this post Link to post Share on other sites
Kajan001 0 Posted April 5 In short: ffmpeg can be used to capture audio but not video because the current libraries are not compatible with the setup. Share this post Link to post Share on other sites
