Hi, I am using Leopardboard and streaming live video. I am using NTSC/PAL camera as input. The output video on the client is deinterlaced but I do not want to use the default deinterlacing method since the method is not good. I want to try various other deinterlacing options provided by gstreamer - "deinterlace" plugin but somehow it does not work. My pipleline is as follows: gst-launch -e v4l2src input-src=composite always-copy=FALSE chain-ipipe=FALSE ! video/x-raw-yuv,format=\(fourcc\)UYVY,width=640,height=480 ! deinterlace mode=1 method=1 ! dmairesizer ! dmaiaccel ! dmaiperf print-arm-load=true ! dmaienc_h264 encodingpreset=2 targetbitrate=1000000 ratecontrol=2 intraframeinterval=23 idrinterval=46 ! queue ! mpegtsmux name=mux ! queue ! udpsink port=3001 host=192.168.1.102 sync=false enable-last-buffer=false The pipeline just does not seem to work. It hangs at the following log: system error: Invalid argument Setting pipeline to PLAYING ... New clock: GstSystemClock Also, to note, If I use IPIPE in continuous mode and make "chain-ipipe=TRUE" then the output remains as it was before i.e. it makes use of default deinterlacing method. If I use the above pipeline without the "deinterlace" plugin or remove "mode=1" from "deinterlace" plugin then I get an interlaced video. But I want to deinterlacing using some other method before encoding. How can I do it? Also, wanted to understand where exactly does the default deinterlacing happen. Is it the IPIPE doing it or encoder or gstreamer? Can I remove or disable the original deinterlacing option or change the deinterlacing method in the hardware? <div>Thanks, Maz </div>
