nvh264enc doesn't handle NV12 frames

[Aniket Hande]

Trying to save MPEG2 TS as an MP4 file. The source codec is mpeg2 and not
H264 so explicitly converting mpeg2 to raw and then trying to encode ot
H264 to save it as an MP4. I'm using nvdec and nvh264enc for decoding and
encoding.

Pipeline as follows:
udpsrc  --> rtpbin  --> depayloader  --> parser  --> queue  --> decoder
--> glcolorconvert  --> format=RGBA  --> gldownload  -->
videoconvert,format=NV12  -->  nvh264enc  --> h264parse  -->  mp4mux  -->
filesink

I'm getting issue with the colorspace conversion, perhaps I'm
doing something wrong?

Debug logs attached.
