DMAI 1.20.00.06 has BUG in non-accel framecopy for YUV420PSEMI data. Instead of
framecopy we will use regular memcpy() to copy upstream buffer in circular
buffer. This helps on enabling videotestsrc on DM6467 platform. And this
be removed once move to later version of DMAI for DM6467.
The below pipeline should work just fine:
gst-launch videotestsrc num-buffers=400 ! 'video/x-raw-yuv,format=(fourcc)NV12'
! TIVidenc1 codecName=h264enc engineName=encode ! filesink
