Kajan001 0 Posted March 28, 2023 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 47 Posted March 28, 2023 hello @Kajan001, which command did you execute for using the cameras? Share this post Link to post Share on other sites
tooz 47 Posted March 29, 2023 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 March 29, 2023 Thanks! I'll do that! Share this post Link to post Share on other sites
Kajan001 0 Posted April 5, 2023 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
