I have had a rough time trying to build a pipeline that will capture/encode and display at the same time. This is the pipeline I'm trying to build that should work:
gst-launch -v v4l2src always-copy=false queue-size=12 num-buffers=2000 ! 'video/x-raw-yuv-strided,format=(fourcc)YUY2,width=1920,height=1080,framerate=(fraction)30/1' ! omxbufferalloc numBuffers=12 ! tee name=t ! queue ! gstperf ! v4l2sink show-preroll-frame=false sync=false min-queued-bufs=2 t. ! queue ! omx_noisefilter ! omx_h264enc force-idr-period=300 i-period=100 bitrate=5000000 ! filesink location=/data1/v4l2cap_again.h264
It outputs/fails as:
root@dm816x-evm:~# gst-launch -v v4l2src always-copy=false queue-size=12 num-buf
fers=2000 ! 'video/x-raw-yuv-strided,format=(fourcc)YUY2,width=1920,height=1080,
framerate=(fraction)30/1' ! omxbufferalloc numBuffers=12 ! tee name=t ! queue !

eue ! omx_noisefilter ! omx_h264enc force-idr-period=300 i-period=100 bitrate=50
00000 ! filesink location=/data1/v4l2cap.h264

Any ideas why omx_noisefilter seems to keep failing? I can capture/encode OR capture/display but I cannot do both concurrently. I have tried with and without queues and moved the tee around but the failure is always he same (or simply cannot connect pads depending on where the tee is at).
Does someone have a working pipeline example to capture/encode/display using v4l2 and gst-launch?
Thanks,
