How to reduce load CPU while stream one flow to two out, one as is, other cropped?

[reeshkov]

I want one stream video from webcam, to two out video, one full and other cropped.

I was try followed command lines, but it is not worked:

Code: Select all

cvlc -vv v4l2:///dev/video0:chroma=YUYV --v4l2-width 1600 --v4l2-height 1200 --sout '#transcode{vcodec=mp2v}:duplicate{dst="rtp{mux=ts,sdp=rtsp://:8888/parking}",dst="transcode{vfilter=croppadd{croptop=650,cropbottom=150,cropleft=200,cropright=900}}:rtp{mux=ts,sdp=rtsp://:8888/moto}"' cvlc -vv v4l2:///dev/video0:chroma=YUYV --v4l2-width 1600 --v4l2-height 1200 --sout '#transcode{vcodec=mp2v}:duplicate{dst="rtp{mux=ts,sdp=rtsp://:8888/parking}",dst="transcode{croptop=650,cropbottom=150,cropleft=200,cropright=900}:rtp{mux=ts,sdp=rtsp://:8888/moto}"'

Now solution is one of next:

Code: Select all

cvlc -vv v4l2:///dev/video0:chroma=YUYV --v4l2-width 1600 --v4l2-height 1200 --sout '#transcode{vcodec=mp2v}:duplicate{dst="rtp{mux=ts,sdp=rtsp://:8888/parking}",dst="transcode{vcodec=mp2v,vfilter=croppadd{croptop=650,cropbottom=150,cropleft=200,cropright=900}}:rtp{mux=ts,sdp=rtsp://:8888/moto}"' cvlc -vv v4l2:///dev/video0:chroma=YUYV --v4l2-width 1600 --v4l2-height 1200 --sout '#duplicate{dst="transcode{vcodec=mp2v}:rtp{mux=ts,sdp=rtsp://:8888/parking}",dst="transcode{vcodec=mp2v,vfilter=croppadd{croptop=650,cropbottom=150,cropleft=200,cropright=900}}:rtp{mux=ts,sdp=rtsp://:8888/moto}"}'

Is there other solution(s) for subject?
