Hi,
I am working on DM8148 , ti-ezsdk / omx_05_02_00_46
My project is to capture pal/ntsc intelaced from CVBS channel and displaying using CVBS output channel + encode.
For this, I used the ti example capture_encode that uses the components:Cap, Dei, Enc, Dis and for displaying to CVBS
I added the component Noise Filter (between DEI (port0) and Dis components. Because 420 is needed for displaying cvbs.
when I worked with bit rate 1000000bps, it works well. but when when I work at 50000bps on the output (by skiping frames
by the capture component). The Display was not good.but when working without noisefilter i.e. output-hdmi low bitrate - It works O.K
