camera capture BA81 format



  • {linux kernel 3.19 QT5.6} QT V4L works perfect.... if I run camera example receive these error

    CameraBin error: "Device '/dev/video0' cannot capture in the specified format"
    CameraBin error: "Could not negotiate format"
    libv4l2: error set_fmt gave us a different result then try_fmt!
    CameraBin error: "Device '/dev/video0' cannot capture in the specified format"
    CameraBin error: "Could not negotiate format"
    

    I know BA81 issue for uvcvideo driver in linux... but in newest kernel I think is solved .... (V4L works very well) .... there is some possibility to set the right format conversion in QT5.6??

    Hi,

    You should also check with GStreamer directly to see if it works. Qt's multimedia backend is GStreamer on Linux.



  • linux ubuntu ba81/gstreamer is not supported ... I install it but the result is the same ... program that use gstreamer return bad input format ....

    Therre is some trik or must use v4l.cpp and buffered image with de-bayer protocol??

    regards
