    initial v1  
    1 The bug is still there. -pixel_format is needed to set the pixel format again already selected by v4l2-ctl before.

    33And for the worse, this will in turn reset some other settings done by v4l2-ctl. For example, exposure mode is changed on some cameras. It seems that the format decision is assumed to take place prior to the other settings. The format can only be changed in close state, while the controls can be changed while capturing. So it may be incorrect to change the pixel format by ffmpeg without the ability to reapply the control settings.
