support for YU12 #187

I cannot get mjpg-streamer to work with Logitech QuickCam Zoom due to this:

# mjpg_streamer -i 'input_uvc.so -y -d /dev/video4'
MJPG Streamer Version: git rev: 43dc7a1413295de5b22868a2f49101064b2c5475
 i: Using V4L2 device.: /dev/video4
 i: Desired Resolution: 640 x 480
 i: Frames Per Second.: -1
 i: Format............: YUYV
 i: JPEG Quality......: 80
 i: TV-Norm...........: DEFAULT
 i: Could not obtain the requested pixelformat: YUYV , driver gave us: YU12
    ... will try to handle this by checking against supported formats. 
 Init v4L2 failed !! exit fatal 
 i: init_VideoIn failed

Any idea?

What does v4l2-ctl --list-formats show?

jose1711 commented 5 years ago 
$ v4l2-ctl --list-formats -d /dev/video4
ioctl: VIDIOC_ENUM_FMT
    Type: Video Capture

    [0]: 'PWC2' (Raw Philips Webcam Type (New), compressed)
    [1]: 'YU12' (Planar YUV 4:2:0)

this fork makes it possible to use this camera but having this feature merged into maintained mjpg-streamer codebase probably makes more sense. output from a simple test:

./mjpg_streamer -i './input_uvc.so -d /dev/video4 -y -r QVGA' -o './output_http.so -p 1234'

hi, I met the same problem, have you ever solved this problem? Does it because mjpeg-streamer not support YU12(YUV420P), what can I do?

jose1711 commented 4 years ago

Nah, I got rid of the camera.
