Hi,
Try this pipeline. I hope that camera you are using will support UYVY format of
raw YUV frame.
gst-launch-0.10 v4lsrc device=/dev/video0 ! capsfilter
caps="video/x-raw-yuv,format=(fourcc)UYVY,width=(int)[16,352],height=(int)[16,288],framerate=(fraction)30/1"
! TIVidenc ! queue ! TIViddec ! TIDmaiVideoSink displayStd=fbdev
displayDevice=/dev/fb/3 videoStd=D1_NTSC videoOutput=COMPOSITE resizer=TRUE
accelFrameCopy=TRUE
With best regards,

Subject: USB Camera and H264 Encoder .....
Hi all,
I am using latest gstreamer dmai plugins, and trying to use video encoder
/decoder and USB Camera.
But I get " Count not negotiate the format" error. Has anybody tried using it
in following way..
USB camera->H264 encode ->H264 Decode-> DmaiVideoSink
(most) USB camera never works with v4l2src element.
Here is the actual pipeline and error message
gst-launch-0.10 v4lsrc device=/dev/video0 ! TIVidenc ! queue ! TIViddec !
TIDmaiVideoSink displayStd=fbdev displayDevice=/dev/fb/3 videoStd=D1_NTSC
videoOutput=COMPOSITE resizer=TRUE accelFrameCopy=TRUE
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4lSrc:v4lsrc0: Could not
negotiate format
Additional debug info:
gstbasesrc..c(2426): gst_base_src_start ():
/GstPipeline:pipeline0/GstV4lSrc:v4lsrc0:
Check your filtered caps, if any
Setting pipeline to NULL ...
FREEING pipeline ....
One reason I could see is , v4lsrc gives I420 format and encoder accepts UYVY ,
is that the reason ..?
Please let me know how to fix this.
regards
Purush
