mchehab: Bom dia! moikka! I guess I'm doing something wrong here because the process just stucks at: __v4l2_ctrl_s_ctrl_int64(sensor->ctrls.pixel_rate, pixel_rate); which is within s_ctrl ... any ideas? hello I have installed mjpegtools but didnt found lavrec and the --playback of lavplay does not show H or C for zoran it seems it uses linux/videodev.h which is V4L1 right ? montjoie: I guess you have a better chance of an answer if you try to write a mail to the mailinglist of the mjpegtools project. regarding my last question... I locked myself out :) ... happens in real life too...
