Deinterlace

[levsh]

Hi!
Is it possible to run vlc with deinterlace filter but without transcode and vcodecs? Only raw data and deinterlace. Source tv-tuner, destination display.

Code: Select all

vlc --vout xv v4l2:// :v4l2-vdev="/dev/video0" :v4l2-input=2 --sout' #transcode{vcodec=mp2v,vfilter=deinterlace{deinterlace=yadif}}:duplicate{dst=display}'

this works fine but i don't need transcode.

Help, what is a right cmdline?

vlc ver. 2.0.1
OS Linux.

Yes of course.

But probably not with the stream output mode.

Sorry for my stupid but how without stream output mode? If i make Open Capture Device from GUI and Video->Deinterlace on, i got "Failed to create video filter2 'deinterlace' Failed to add filter 'deinterlace' " and hence image still interacle.

Ah then maybe deinterlacing does not work with the chroma coming from your camera. I guess it's the evil YUY2...

yes

You should force I420 as the capture chroma: vlc --v4l2-chroma I420 --v4l2-use-libv4l2
