<blockquote style='border-left:2px solid #CCCCCC;padding:0 1em' style="border-left:2px solid #cccccc;padding:0 1em" class="gmail_quote"> I have same issue with my notebook
webcam. When you run GST_DEBUG=4 gst-launch v4l2src !
xvimagesink it should print out <br>
<br>
v4l2
gstv4l2object.c:2729:gst_v4l2_object_get_caps:<v4l2src0>
probed caps: video/x-raw, format=(string)YUY2,
width=(int)1280, height=(int)720,
pixel-aspect-ratio=(fraction)1/1,
interlace-mode=(string)progressive, framerate=(fraction){
10/1 }; video/x-raw, format=(string)YUY2, width=(int)960,
height=(int)544, pixel-aspect-ratio=(fraction)1/1,
interlace-mode=(string)progressive, framerate=(fraction){
10/1 }; ... and much more<br>
<br>
one of the caps is "video/x-raw, format=(string)I420,
width=(int)1280, height=(int)720,
pixel-aspect-ratio=(fraction)1/1,
interlace-mode=(string)progressive, framerate=(fraction){
30/1 }"<br>
<br>
so first caps which is printed is YUV2 format but only
10fps. but there is I420 which enable 30fps. So try run your
piepline with GST_DEBUG=4 so you find out all supported caps
to find suitable format.<br>
