Hi Amit,

I appreciate you sending this in. People have asked about Jetson
support a few times.

Is there any plan to enable the normal nvdec/nvenc APIs on jetson?
There is support on 'normal' ARM systems.

More specifically to this change, we already have a v4l2m2m driver. Why
is this completely separate? Can it share code? Can it be written to
just conditionalise the parts that are different? What are those parts?

What is the problem with mpeg4 containers? Is this the annex b thing?
if so, you need to enable the bitstream filter.
