Hi,

In order to solve the jag of PAL, I test the demo(..\ti_tools\hdvpss_01_00_01_37\packages\ti\psp\examples\common\vps\m2m\m2mDeiScale\M2mDeiScale_main.c).But one question still confuse me, In yuv420 mode I send a filed to DEI , a frame come out . In my mind , maybe two fileds(even and odd ) sent to DEI, one frame come out. So the DEI module double the frame rate ? But why ?

    Hello,

    What is the software release that you are using here?

    Could you try with progressive video are you observe the same problem?

    In EZSDK software release when gstreamer is used the the dei-scaler element(s), by default outputs at twice the framerate for interlaced content. For progressive content the default output framerate is the same as input framerate. For example, if the input is 1920x1080i 30 frames per second (or 60 fields per second) - the deiscaler element outputs 60 frames per second. To control the output framerate coarsely, the deiscaler element(s) provides the framerate-divisor property.
